radare2-mcp

MCP server exposing radare2 and Rizin binary analysis capabilities. Provides 85 tools covering static analysis, disassembly, decompilation, ESIL emulation, live debugging, vulnerability scanning, and exploit development -- all through structured JSON responses over the Model Context Protocol.

What it does

Static Analysis (19 tools)

Open binaries, list functions/imports/exports/strings/sections/classes, disassemble and decompile functions, read/write bytes, rename functions, add comments, find crypto constants, list PE resources and relocations.

Advanced Analysis (10 tools)

One-shot binary triage, deep single-function analysis, constraint extraction for crackmes, ESIL execution tracing, automated vulnerability pattern scanning, crackme solver, IOC extraction, exploit development assistant, binary diffing, file format parsing.

ESIL Emulation (10 tools)

Persistent ESIL VM sessions with register/memory read-write, single-step and run-to-address, raw ESIL expression evaluation. State is preserved across tool calls for multi-step emulation workflows.

RzIL Emulation (16 Rizin-based tools)

Typed bitvector emulation via Rizin's RzIL backend. IL AST lifting, individual CPU flag access, calling convention analysis, enhanced type and symbol queries.

Live Debugging (18 tools)

Three session patterns: cached sessions for static analysis (reused across calls, 5-min TTL), persistent debug sessions (UUID-identified, survive across calls), persistent ESIL/RzIL sessions (same pattern, for emulation state).

All user input is validated through sanitize.ts before being passed to r2. Binary paths are checked against ALLOWED_DIRS with symlink resolution. The r2_command tool restricts commands to a safe allowlist.

Security

  • No arbitrary command execution -- r2_command uses an allowlist

  • Path validation with symlink resolution and ALLOWED_DIRS enforcement

  • Comments are base64-encoded to prevent r2 command injection

  • Search queries are sanitized against shell metacharacters

  • Local only -- r2pipe spawns local processes, MCP runs over stdio

add_commentB

Add or update a comment at a specific address in the binary.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressYesHex address (e.g. "0x08048000")
commentYesComment text to add at the address
binary_pathYesAbsolute path to the binary file

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden of behavioral disclosure. It does reveal that the operation can both add and update an existing comment, but it does not explain side effects such as persistence, overwriting behavior, whether the binary file is modified, or any required permissions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence that is front-loaded with the core action and scope. Every word is useful and there is no redundant content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The schema fully covers the required parameters and the tool is conceptually simple, so the description is minimally adequate. However, the lack of behavioral context—especially whether the comment is stored as metadata or written into the binary—leaves an important gap for an agent deciding how to use the tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already documents all three parameters with 100% coverage. The description adds no extra semantic detail beyond what the schema provides, so the baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb, resource, and scope: 'Add or update a comment at a specific address in the binary.' It clearly conveys what the tool does and is distinguishable from all sibling tools, none of which are comment-related.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternatives, nor any mention of whether comments are persistent metadata or modifications to the binary file itself. The agent is left to infer the appropriate context for invoking it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

analyze_binaryB

Open and analyze a binary file, returning architecture, platform, entry point, and binary metadata as JSON.

ParametersJSON Schema
NameRequiredDescriptionDefault
binary_pathYesAbsolute path to the binary file
analysis_levelNoAnalysis depth level (aa=basic, aaa=standard, aaaa=experimental)aaa

TDQS

B3.2/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description says the tool opens and analyzes a file and returns JSON, which signals a read-oriented operation. However, with no annotations, it does not explicitly state side-effect-free behavior, whether a persistent session/project is created, or what happens if the path is invalid; this leaves some behavioral ambiguity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One focused sentence, front-loads the operation and states the return format. No filler or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Because there is no output schema and no annotations, and because the binary-analysis toolbox contains several overlapping tools, the description is not complete enough: it lacks selection guidance and explicit assurance about side effects/state changes. It does at least list the main returned fields, preventing the score from being 1.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the schema already documents binary_path and analysis_level with enum semantics and a default. The description adds no additional parameter-level meaning, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific action (open and analyze), a resource (a binary file), and the outputs (architecture, platform, entry point, binary metadata) returned as JSON. It stops short of explicitly contrasting itself with overlapping siblings like triage_binary or file_format_analyzer, but the output scope makes the tool's purpose clear.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given on when to use analyze_binary versus triage_binary, file_format_analyzer, binary_headers, or analyze_types. The description only states the operation with no exclusions or alternative routing, leaving tool selection to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

analyze_function_deepA

Deep single-function analysis: disassembly, decompilation, variables, xrefs, callers, callees, strings, and complexity metrics in one call.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoHex address of the function (e.g. "0x08048000")
binary_pathYesAbsolute path to the binary file
function_nameNoName of the function to analyze (e.g. "main")

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It does convey that this is a read-only aggregate analysis scoped to one function, which is meaningful context. But it omits how the target function is selected given that address and function_name are both optional in the schema, and it says nothing about output format, error conditions, or the potential cost of a deep analysis.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single dense sentence that front-loads the core purpose ('Deep single-function analysis') and then lists the value-adding specifics with a colon and comma-separated enumeration. No filler, no redundancy; every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description usefully inventories the returned data, which partially compensates for the missing output schema. However, this is a complex aggregator tool with no annotations, and the description leaves a genuine gap: only binary_path is required while address and function_name are optional, yet the tool is described as analyzing one function. Function identification precedence, failure behavior, and runtime cost are all unexplained.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all three parameters are already documented in the schema. The description adds only the framing that the analysis targets a single function; it does not clarify the relationship between address and function_name, which takes precedence, or whether either is effectively required. This stays at the baseline of 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and scope ('Deep single-function analysis') and enumerates the concrete deliverables: disassembly, decompilation, variables, xrefs, callers, callees, strings, and complexity metrics. The 'in one call' phrasing clearly distinguishes it from narrower siblings like disassemble, decompile_function, and get_xrefs.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'in one call' phrasing implies this is the tool to use when a comprehensive view of a single function is needed rather than making several individual calls. However, no alternative sibling is explicitly named and no when-not-to-use conditions are given, leaving the agent to infer when it should prefer disassemble or decompile_function for narrower queries.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

analyze_typesA

List type definitions from binary analysis including structs, enums, and typedefs.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
filterNoOptional substring to filter type names
offsetNoPagination offset (0-based)
binary_pathYesAbsolute path to the binary file

TDQS

A3.5/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description must carry the behavioral burden. 'List' clearly communicates a read-only operation, which is helpful, but the description adds no detail about output shape, ordering, filtering behavior, or pagination implications beyond what the schema already exposes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single, front-loaded sentence states the action, resource, and examples without filler. Every word earns its place, and the key scope terms 'structs, enums, and typedefs' appear immediately.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a fairly simple listing tool, and the schema documents all parameters, making the description mostly sufficient. However, there is no output schema, and the description does not clarify the returned structure or behavior, nor does it provide guidance relative to sibling tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema covers all parameters with descriptions, so the baseline is 3. The tool description does not add any parameter-level meaning beyond the schema, such as how 'filter' interacts with type names or how pagination relates to the listing.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description specifies a clear verb and resource: 'List type definitions from binary analysis' and explicitly enumerates structs, enums, and typedefs. It is specific enough to convey what the tool returns, though it does not explicitly differentiate itself from the similarly named sibling 'rz_types'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The intended use is implied by the description: an agent would invoke this when it needs type definitions from a binary. However, the description provides no explicit guidance about when to prefer this tool over alternatives, and no exclusions or context clues are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

binary_headersB

Show PE/ELF/Mach-O headers with detailed field information.

ParametersJSON Schema
NameRequiredDescriptionDefault
binary_pathYesAbsolute path to the binary file

TDQS

B3.3/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full behavioral burden. The verb 'Show' implies a read-only inspection and the description indicates it reads binary file headers, which is useful. However, it does not disclose behavior for invalid or unsupported binaries, error conditions, or whether any analysis is performed versus a simple header dump.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single informative sentence with no filler. It front-loads the core action, specifies the supported binary formats, and adds the detail-level qualifier, making it easy for an agent to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is adequate for a simple single-parameter read tool, but with no output schema and no annotations, it leaves the agent without information about the return structure or how this differs from overlapping siblings like file_format_analyzer. More context about output shape or intended use cases would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the single parameter binary_path is already well-described as 'Absolute path to the binary file'. The tool description adds no additional parameter context, but none is necessary given the schema already fully documents the only parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Show') and a clear resource ('PE/ELF/Mach-O headers') with a qualifier about detailed field information. It is unambiguous about what the tool does, but it does not differentiate itself from sibling tools like file_format_analyzer or analyze_binary that might also inspect binary formats.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given about when to prefer this tool over alternatives such as file_format_analyzer, analyze_binary, or list_sections. There are no stated exclusions or selection criteria, leaving the agent to infer usage solely from the tool name and description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_attachA

Attach the radare2 debugger to a running process by PID and return a persistent session ID.

ParametersJSON Schema
NameRequiredDescriptionDefault
pidYesProcess ID to attach to

TDQS

A3.8/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description carries the full burden. It discloses that a persistent session ID is returned, but omits material behavioral traits such as attaching typically suspending the target process, requiring OS-level permissions, and creating a session used by sibling debug_* tools. This is a meaningful transparency gap for a debugger attach operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single, well-structured sentence that front-loads the action, target, and return value with no filler. Every word contributes to the agent's understanding.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter tool with full schema coverage, the description provides the essential call information: what to attach to and what will come back. It lacks behavioral side-effect details, but those are already penalized under behavioral transparency; the tool is still invokable correctly with the information given.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%: the only parameter, 'pid', is fully documented as 'Process ID to attach to'. The description adds no additional parameter-specific meaning, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Attach'), a specific resource ('the radare2 debugger to a running process by PID'), and a clear outcome ('return a persistent session ID'). This distinguishes it from siblings like debug_launch and debug_detach without needing to inspect their schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'running process by PID' clearly signals the intended use case for already-running processes, contrasting implicitly with debug_launch for starting processes. It does not explicitly name alternatives or state when not to use it, but the context is clear enough for an agent.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_continueA

Continue execution of the debugged process until a breakpoint is hit, an address is reached, or the process exits.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idYesDebug session ID
timeout_msNoTimeout in milliseconds (default 5 minutes)
until_addressNoStop at this address (sets temporary breakpoint). If omitted, continues until next breakpoint or exit.

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the behavioral disclosure burden. It clearly explains the main loop and termination conditions, but it does not mention that the call blocks until a condition is met or timeout_ms expires, nor what side effects occur when the process exits (e.g., session state changes). These are meaningful gaps for a tool that can run for minutes by default.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Exactly one sentence with no filler. The core purpose is front-loaded, and each clause adds meaningful information about the stop conditions. This is an appropriately concise definition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple, the schema fully documents parameters, and the description covers the core behavior, so an agent can likely invoke it correctly. However, with no output schema or annotations, the description does not explain the return behavior, blocking semantics, or how the session state changes after exit or timeout, which would aid a less experienced agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description's 'until an address is reached' loosely mirrors the until_address parameter, but it adds no detail beyond the schema's own explanation. The timeout_ms and session_id parameters are not enhanced by the description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Continue execution'), a clear resource ('the debugged process'), and explicit termination conditions (breakpoint, address, exit). This distinguishes it from debug_step (single-step) and the esil/rzil run variants, which operate on emulated environments rather than a debugged process.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'Continue execution' implies the tool is used to resume a paused debug session, but it never explicitly states when to use it versus debug_step or other debug controls. No exclusions or alternative tools are named, leaving the agent to infer the proper context from the sibling list and schema.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_detachA

Detach from the debugged process, leaving it running, and close the debug session.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idYesDebug session ID returned by debug_launch or debug_attach

TDQS

A4.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the burden of disclosing behavior. It explains the core contract: the process survives the detach and the debug session is closed. This is the most important behavioral trait distinguishing it from kill/cleanup operations, though it does not discuss errors or post-conditions such as whether breakpoints are cleared.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single, front-loaded sentence with no filler. Every clause contributes: action, process outcome, and session outcome.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter tool with a fully documented schema and no output schema, this description is sufficient to invoke it correctly. It could add a note about error conditions or relation to debug_kill, but nothing essential is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already documents session_id with 100% coverage, including its source ('returned by debug_launch or debug_attach'). The description adds no additional parameter-level meaning, so it stays at the schema-coverage baseline of 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Detach'), the resource ('debugged process'), and the intended outcome ('leaving it running', 'close the debug session'). This clearly distinguishes it from sibling debug_kill, which would terminate the process.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'leaving it running' provides clear usage context: use this when you want to end debugging but keep the target process alive, as opposed to debug_kill. It does not explicitly name alternatives or exclusions, but the behavior is unambiguous for this debugger toolset.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_get_backtraceB

Get the call stack backtrace of the debugged process.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idYesDebug session ID

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full behavioral disclosure burden. It implies a read-only operation via 'Get', but it does not mention preconditions, error behavior, whether the process must be paused, or what happens if the session is invalid. The description is not misleading but is minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence with no filler. The core action and target are front-loaded, and every word contributes to the meaning.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter tool this is nearly adequate, but with no output schema the description does not hint at the return format or the kind of information a backtrace contains. It also lacks usage context, so an agent must infer when and how to invoke it beyond what the schema provides.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema already describes session_id as 'Debug session ID' and coverage is 100%, so the description does not need to add much. It adds no extra semantic detail beyond the schema, which is acceptable given how thoroughly the schema documents the only parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Get') and a specific resource ('call stack backtrace of the debugged process'), making the operation immediately clear. It is also distinguishable from sibling debug_get_* tools such as debug_get_registers or debug_get_threads because 'backtrace' is a unique and concrete resource.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool over alternatives. It does not mention prerequisites, such as an active or paused debug session, and does not contrast itself with sibling debug_get_* tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_get_infoA

Get debug session information including PID, status, executable path, and command line.

ParametersJSON Schema

session_idYesDebug session ID

TDQS

A3.8/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly indicates this is an information-retrieval operation and lists the returned fields, implying a read-only action. It does not disclose behavior for invalid or stale session IDs, or explicitly state that no state is modified.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, well-structured sentence with zero filler. It front-loads the action and resource, then immediately enumerates the meaningful return fields, earning every word's place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple one-parameter read-only tool, the description is largely complete: it names the tool's purpose and return content. It could be improved by mentioning that session IDs come from debug_list_sessions, but the core information needed to invoke and interpret the tool is present.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% because session_id is described as 'Debug session ID'. The description does not add extra detail about session_id format, how to discover valid values, or failure behavior, but the schema already documents the parameter adequately, so a baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Get') with a clear resource ('debug session information') and enumerates the exact data returned: PID, status, executable path, and command line. This clearly distinguishes it from sibling tools like debug_get_threads or debug_get_backtrace, which target different aspects of a debug session.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use the tool: when an agent needs details about an existing debug session identified by session_id. However, it does not explicitly mention alternatives, exclusions, or the prerequisite of first listing sessions via debug_list_sessions to obtain a valid session ID.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_get_mapsA

List memory maps of the debugged process with addresses, sizes, and permissions.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idYesDebug session ID

TDQS

A3.6/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description is the sole source of behavioral context. The verb 'List' implies a read-only operation and the output fields are mentioned, but it does not explicitly state that it does not modify state, that an active session is required, or how errors are handled. This is adequate for a simple getter but not richly transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no filler. It front-loads the action and includes only essential information: verb, resource, scope, and output content. Every phrase earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter, read-only listing tool with no output schema, the description covers what it does and what it returns. It lacks explicit mention of session lifecycle requirements and exact output structure, but the operation is simple enough that the definition is nearly complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already fully documents session_id with 100% coverage, so the baseline is 3. The description only adds a weak semantic link between the session and the debugged process, but does not provide additional parameter-level detail beyond the schema. No further compensation is needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('List') with a clear resource ('memory maps') and specifies the returned fields ('addresses, sizes, and permissions'). It is easily distinguished from siblings like debug_read_memory or debug_get_registers, making the tool's purpose unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no guidance on when to use this tool versus alternatives such as debug_get_info or debug_read_memory, nor does it mention prerequisites like having an active debug session. Usage is only implied by the name and one-line purpose, which is minimal guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_get_registersA

Read all register values or a specific register from the debugged process.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idYesDebug session ID
register_nameNoSpecific register to read (e.g. "rax", "eip"). If omitted, returns all registers.

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description carries the behavioral burden. The verb 'Read' makes the non-mutating nature clear and the all-or-specific behavior is disclosed. However, it does not mention active-session requirements, process-pause expectations, or error behavior. Acceptable but not rich.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence that puts the verb first, states the main behavior, then adds the optional narrowing and scope. There is no filler or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple two-parameter getter with no output schema, the description covers what is read and from where, and the schema covers parameter semantics. It does not describe return formatting or edge cases, but those are less critical for a register read tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%: session_id and register_name are already documented. The description adds only the 'all or specific' framing, which reinforces the schema's 'If omitted, returns all registers' note but provides no new parameter-level meaning. Baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific operation ('Read'), a resource ('register values'), a scope ('from the debugged process'), and the all-or-specific behavior. This clearly distinguishes it from debug_set_register (write operation) and from emulation-based register readers like esil_get_registers and rzil_get_registers.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'from the debugged process' provides clear context for selecting this tool over emulation-focused siblings. It does not explicitly name alternatives or state when not to use it, but the context is unambiguous enough that an agent can infer the appropriate use case.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_get_threadsA

List all threads in the debugged process with their status.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idYesDebug session ID

TDQS

A3.6/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the burden of behavioral disclosure. 'List' implies a read-only operation and 'with their status' hints at the return content, but it does not mention session requirements, error behavior, or cost/scale caveats. This is adequate but not detailed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is one short sentence with no filler. The core action and result are front-loaded and every word contributes to meaning.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter read-only listing tool, the description is nearly complete: it names the resource, scope, and status output. The only gaps are optional details like output format or failure conditions, which are less critical given the schema and simple operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the single required parameter (session_id) is already documented as 'Debug session ID'. The description adds no param-level detail, so the schema does the heavy lifting; baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('List') and identifies the exact resource ('all threads in the debugged process') plus the key output attribute ('with their status'). This clearly differentiates it from sibling debug tools like debug_get_registers or debug_get_backtrace.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no guidance on when to choose this over alternatives or what prerequisite conditions apply (e.g., an attached/running debug session). It neither names siblings nor states exclusions, so an agent must infer usage from the tool name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_killA

Kill the debugged process and close the debug session.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idYesDebug session ID returned by debug_launch or debug_attach

TDQS

A4/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full behavioral disclosure burden. It clearly states the destructive effect of killing the process and the session-state change of closing the debug session. It does not mention reversibility, but 'kill' inherently signals non-reversible termination.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single front-loaded sentence with no filler. Both the primary action and the secondary effect are communicated efficiently.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple one-parameter tool with no output schema, the description covers the action, the target, and the resulting session state. It could optionally point to debug_detach as a non-destructive alternative, but that is not essential for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The only parameter, session_id, is documented in the schema with a clear description referencing debug_launch and debug_attach, giving 100% schema coverage. The description adds no additional parameter semantics, but the baseline applies because the schema already handles it.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Kill') and resource ('the debugged process'), then adds the session-closing outcome. This clearly distinguishes it from related debug lifecycle tools like debug_detach and debug_continue.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies this is the termination action for an active debug session, but it does not explicitly say when to use it versus debug_detach or debug_remove_breakpoint. No alternatives or exclusions are mentioned, so usage guidance is only implied by the semantics.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_launchA

Launch a binary under the radare2 debugger and return a persistent session ID for subsequent debug commands.

ParametersJSON Schema
NameRequiredDescriptionDefault
binary_pathYesAbsolute path to the binary file to debug

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden of behavioral disclosure. It does state that the tool launches a binary under the debugger and returns a persistent session ID, which is the core behavioral contract. However, it omits useful details such as whether the launched process automatically pauses at the entry point, what side effects the launch has on the system, or what happens on failure. This is adequate but not rich.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, well-structured sentence that states the action, the target, and the return value without any unnecessary words. The most important information (launching and session ID) is front-loaded, making it easy to scan.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description explicitly communicates the essential return value (persistent session ID) and its role in subsequent debugging commands. The single-parameter input is fully covered by the schema. It would be slightly more complete with information about the expected session ID format or common failure modes, but for a launch tool of this simplicity it is largely adequate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema already provides 100% description coverage for the only parameter, binary_path, with a clear description. The tool description adds no additional parameter-level semantics beyond naming the binary. Baseline 3 is appropriate because the schema does all the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Launch'), identifies the exact resource ('binary under the radare2 debugger'), and states the key output ('persistent session ID'). This makes it easy to distinguish from sibling tools like debug_attach, which likely attaches to an already-running process rather than launching a new binary.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'for subsequent debug commands' clearly places this tool as the entry point for a debugging workflow, implying it should be called before tools like debug_continue or debug_get_registers. However, it does not explicitly contrast with debug_attach or mention any exclusions, so the guidance is strong context but not fully explicit alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_list_breakpointsA

List all active breakpoints in the debug session with their addresses and status.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idYesDebug session ID

TDQS

A3.6/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the behavioral disclosure burden. It does convey the read-only listing behavior and the scope of results ('active', with addresses and status), but it does not mention error behavior for invalid sessions, whether inactive breakpoints are excluded, or other side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no filler. The verb, scope, and result contents are all front-loaded, making it easy to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a low-complexity list operation with one required parameter, the description adequately covers what the tool does and what the response contains. It could add a note about requiring an active debug session, but the required session_id parameter and sibling context make that reasonably inferable.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% because session_id is described as 'Debug session ID'. The description adds no parameter-level detail beyond that, meeting the baseline but not enriching the agent's understanding of the parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('List') and resource ('all active breakpoints in the debug session'), and names the returned attributes (addresses and status). It clearly distinguishes from sibling tools like debug_set_breakpoint and debug_remove_breakpoint by being the read-only enumeration operation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance is given on when to use this tool versus alternatives, nor on prerequisites such as requiring an active debug session. The phrase 'in the debug session' implies prior setup but does not state it, leaving the agent without clear selection criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_list_sessionsA

List all active debug sessions with their session IDs, targets, and PIDs.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A4.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the burden of disclosing behavior. It clearly indicates a read-only listing operation and specifies the scoping ('active') and returned fields. For a simple list tool, this is sufficient behavioral transparency, though it does not explicitly say it never mutates state.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence with no filler. Every word contributes meaning: it states the action, the scope, and the return content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter list operation with no output schema, the description is complete. It tells the agent exactly what the tool returns and is unambiguous in context with the sibling tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool accepts zero parameters and the schema description coverage is 100%, so the schema already fully documents the parameter surface. The description has no need to add parameter semantics, matching the baseline for zero-parameter tools.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb ('List'), a precise resource ('active debug sessions'), and the exact output fields ('session IDs, targets, and PIDs'). This clearly distinguishes it from sibling tools like esil_list_sessions and rzil_list_sessions.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'active debug sessions' gives clear context for when the tool should be used, and the mention of PIDs reinforces that this is for native debug sessions rather than ESIL/RZIL sessions. However, it does not explicitly name alternatives or state when not to use this tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_read_memoryA

Read memory from the debugged process at a specific address, returned as hex string or formatted hexdump.

ParametersJSON Schema
NameRequiredDescriptionDefault
countNoNumber of bytes to read (default 64)
formatNoOutput format: "hex" for raw hex, "hexdump" for formatted dumphexdump
addressYesHex address to read from (e.g. "0x08048000")
session_idYesDebug session ID

TDQS

A4.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full behavioral burden and it does convey the key trait: this is a non-mutating read operation. It also tells the caller the two possible return representations. It does not cover error behavior for unmapped or inaccessible addresses, but that is a secondary concern for a simple read primitive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence contains the essential action, target, and return format with no redundant wording. It is front-loaded and immediately scannable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the rich schema covering address, count, format, and session ID, the description is adequate for invoking the tool correctly. Since there is no output schema, the description's mention of 'hex string' versus 'formatted hexdump' provides important return-shape context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All four parameters are already described in the schema, so schema description coverage is 100%. The description adds no parameter-specific detail beyond what the schema already provides, so the baseline score of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear action ('Read memory'), specifies the target ('debugged process'), the location ('specific address'), and the output forms ('hex string or formatted hexdump'). The 'debugged process' scoping clearly separates it from static file reads like read_bytes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description establishes the intended context: live debugged process memory rather than static binary contents. It does not explicitly name alternatives or exclusion cases, but the process-scoped wording makes the correct use obvious among the many debug/read siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_remove_breakpointA

Remove a breakpoint at the specified address or remove all breakpoints.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoHex address of the breakpoint to remove. Omit to remove all breakpoints.
session_idYesDebug session ID

TDQS

A3.9/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses the key destructive behavioral trait, including the 'remove all breakpoints' mode, which is important context. No annotations are provided, so the description carries the burden; it does not discuss error behavior, idempotency, or session state requirements, but for a simple debugger control tool the main side effect is covered.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One compact sentence front-loads the verb and clearly encodes both removal modes with no filler. Every word earns its place and the structure is immediately scannable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a low-complexity two-parameter tool with no output schema, the essential invocation facts are present: session_id is required and address is optional. However, it lacks explicit notes on active-session prerequisites, error handling, or return status, so it is adequate but not comprehensive.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with both parameters already described in the input schema. The description's 'specified address or remove all' mirrors the schema's 'Omit to remove all breakpoints' without adding new parameter-level detail, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('Remove a breakpoint') on a clear resource, with two explicit modes: by address or all breakpoints. This cleanly distinguishes it from related siblings like debug_set_breakpoint and debug_list_breakpoints.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context for when to use the tool: whenever a breakpoint needs to be removed, either a single one at a specified address or all breakpoints at once. It does not explicitly name alternatives or exclusions, but the usage context is unambiguous.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_set_breakpointC

Set a software breakpoint at the specified address in the debugged process.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressYesHex address for the breakpoint (e.g. "0x08048000")
hardwareNoUse hardware breakpoint instead of software
session_idYesDebug session ID

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only names the action without explaining that breakpoints persist, that software breakpoints patch process memory, that the hardware parameter changes the mechanism, or what happens with invalid addresses. For a mutating debugger operation, this is thin.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no filler, and the action and target are front-loaded. It is appropriately concise, though the omission of the hardware behavior means some useful information was sacrificed for brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no annotations, no output schema, and a state-changing operation, a one-sentence description is not operationally complete. An agent can fill the parameters from the schema but cannot predict return values, failure modes, session prerequisites, or cleanup behavior. Additional context about hardware mode and session state would be needed for a safe call.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description adds minimal parameter semantics: 'address' is already documented, and session_id and hardware are only described in the schema. It does not provide any additional context about how the parameters interact or when hardware should be true.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear verb and resource: set a breakpoint at a specified address in a debugged process, and it is distinguishable from debug_remove_breakpoint and debug_list_breakpoints. However, it says 'software breakpoint' while the schema exposes a hardware flag, so it narrows the tool's actual scope and could mislead an agent into thinking hardware breakpoints are unsupported.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit guidance on when to use this tool versus alternatives, nor any mention of prerequisites such as an active debug session. The phrase 'debugged process' and the session_id parameter imply a session must exist, but the description never states this or explains that breakpoints should be removed via debug_remove_breakpoint.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_set_registerB

Set a register value in the debugged process.

ParametersJSON Schema
NameRequiredDescriptionDefault
valueYesValue to set (hex string, e.g. "0x41414141")
session_idYesDebug session ID
register_nameYesRegister name (e.g. "rax", "eip", "rflags")

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden of behavioral disclosure. It fails to mention that setting a register mutates the debuggee's state, can affect execution flow, or requires an active debug session. The description is not misleading, but it is under-disclosing for a state-changing debugger operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, succinct sentence with no redundant content. It is appropriately front-loaded for a simple setter tool, though it sacrifices some useful behavioral detail for brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutation tool with no annotations and no output schema, the description is too sparse. It does not mention return values, failure modes, or side effects on the debugged process, and it assumes the user already knows to provide an existing debug session ID.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the parameter descriptions already provide examples and types for value, register_name, and session_id. The tool description adds no additional parameter-level meaning, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a clear verb+resource pair: 'Set a register value' in the 'debugged process'. It is unambiguous about what the tool does, but it does not differentiate it from sibling tools like esil_set_register or rzil_set_register, which also set register values in emulator contexts.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'in the debugged process' and the required session_id imply this is for live debug sessions, which is useful context. However, the description gives no explicit guidance about when to use this over alternatives such as esil_set_register, rzil_set_register, or debug_write_memory, and no exclusions are stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_stepA

Single-step the debugged process (step into or step over) and return the updated register state.

ParametersJSON Schema
NameRequiredDescriptionDefault
countNoNumber of instructions to step (default 1)
step_overNoStep over calls instead of stepping into them
session_idYesDebug session ID

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden of behavioral disclosure. It does clearly indicate that this tool advances (mutates) the debugged process's execution state and returns registers. However, it omits important behavioral context, such as the requirement for an active/paused debug session, the potential long-running effect when stepping over calls, and what happens at process exit.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single compact sentence that front-loads the core action, includes the key behavioral choice (step into/over), and states the return value. There is no fluff or redundancy, making it easy for an agent to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a stateful debugger operation with no annotations and no output schema, the description is adequate but sparse. It covers the main purpose and return value, but it does not explain prerequisites like an active paused session, the behavior when stepping over a call, or the structure of the returned register state. An agent familiar with debuggers can use it, but more context would reduce ambiguity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema covers 100% of parameters with useful descriptions (count, step_over, session_id), so the description does not need to add much. It reinforces the step_over meaning by saying 'step into or step over', but it does not provide any parameter semantics beyond what the schema already offers.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb and resource: 'single-step the debugged process', with explicit step into/step over behavior and a defined return value (updated register state). This clearly differentiates it from sibling tools like debug_continue (run freely), debug_get_registers (read-only register access), and esil_step/rzil_step (emulation-based stepping).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description states what the tool does but not when to choose it over alternatives such as debug_continue for continuous execution or the emulation stepping tools. Usage must be inferred from the tool name and the debugger context; there is no explicit when-to-use or when-not-to-use guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

debug_write_memoryC

Write memory in the debugged process at a specific address using hex bytes or a string.

ParametersJSON Schema
NameRequiredDescriptionDefault
dataNoString data to write (used when as_string is true)
addressYesHex address to write to (e.g. "0x08048000")
as_stringNoIf true, write data as an ASCII string; otherwise write hex_bytes
hex_bytesNoHex bytes to write (e.g. "90909090" for NOPs)
session_idYesDebug session ID

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full responsibility for behavioral disclosure. It states that the tool writes to debugged process memory, but it does not warn that this is destructive to the target process state, can crash the debuggee, or requires the debug session to be alive. The mutating and potentially harmful nature of the operation is under-communicated.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence with no redundant wording. It is front-loaded with the core action and resource, but it sacrifices important behavioral clarity for brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool that mutates process memory and has no output schema or annotations, this description is incomplete. It does not mention whether the write is immediate, whether it can corrupt execution, what the return value is, or that an active session is mandatory—all relevant for safe invocation by an agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so every parameter is already documented in the input schema. The description's mention of 'hex bytes or a string' mirrors the `hex_bytes` and `data`/`as_string` parameters but adds no extra semantic detail, such as how `hex_bytes` and `data` interact or what happens when both are provided.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear action ('Write memory in the debugged process at a specific address') and identifies the two data modes ('hex bytes or a string'). It is specific enough to understand the operation, though it does not explicitly distinguish this from the sibling `write_bytes` tool, which could also be interpreted as writing bytes somewhere.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given about when to use this tool versus alternatives like `write_bytes` or `debug_read_memory`. The description does not mention prerequisites such as an active debug session or caution about using it only when intentional memory modification is required.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

decompile_functionA

Decompile a function to pseudo-C representation using the available decompiler backend.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoHex address of the function (e.g. "0x08048000")
backendNoDecompiler backend: "auto" tries pdg (r2ghidra) first then falls back to pdc, "pdc" uses r2 native, "pdg" uses r2ghidraauto
binary_pathYesAbsolute path to the binary file
function_nameNoName of the function to decompile (e.g. "main")

TDQS

A3.6/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the burden of disclosing behavior. It does add the output type and mentions backend selection, but it does not state whether the operation is read-only, whether the binary must already be analyzed, or what happens when neither address nor function_name is provided.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence that conveys the core action and output without filler. Every word earns its place, and it is appropriately compact.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description leaves important operational context unsaid: how the function is identified (address vs. function_name), whether one must be supplied, what the pseudo-C output looks like, and whether there are prerequisites like prior analysis. With no output schema or annotations, this is a significant completeness gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all four parameters. The description adds little beyond the schema, but it does not need to compensate since the parameter meanings are fully covered in the input schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Decompile'), a specific resource ('a function'), and a concrete output form ('pseudo-C representation'), which clearly distinguishes this from siblings like disassemble or get_function_info. The action and output are unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The purpose implies when to use it: when a pseudo-C representation of a function is needed. However, it gives no explicit guidance on when not to use it or which sibling alternative to choose, such as disassemble, analyze_function_deep, or get_function_info.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

diff_binariesA

Compare two binary versions: find added, removed, and changed functions, imports, strings, and show instruction-level diffs for modified functions.

ParametersJSON Schema
NameRequiredDescriptionDefault
binary_path_aYesAbsolute path to the first (original) binary
binary_path_bYesAbsolute path to the second (patched) binary
max_function_diffsNoMaximum number of changed functions to show instruction-level diffs for

TDQS

A3.9/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It does reveal meaningful behavior: it finds several categories of differences and can produce instruction-level diffs for modified functions. However, it does not state whether the tool performs its own analysis, requires already-loaded binaries, is read-only, or has notable performance implications on large binaries.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, dense sentence that front-loads the core purpose and immediately lists the concrete outputs. Every clause adds useful information, with no filler or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The input schema is well-documented and the description lists the output categories, but no output schema exists and the description does not explain the return format or result structure. For a binary diffing tool of this complexity, an agent would benefit from knowing how results are organized and whether pre-analysis is required before invoking the tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline applies: the schema already documents binary_path_a, binary_path_b, and max_function_diffs clearly. The description's mention of 'instruction-level diffs for modified functions' loosely aligns with max_function_diffs but does not add substantial semantic value beyond what the parameter descriptions already state.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the tool as binary version comparison, with a specific verb ('Compare') and a concrete resource ('two binary versions'). It enumerates exactly what kinds of findings are produced: added/removed/changed functions, imports, strings, and instruction-level diffs, which clearly distinguishes it from analytical siblings like analyze_binary or list_functions.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description strongly implies the appropriate use case: when an agent needs to compare two versions of a binary to identify differences. It does not explicitly name alternatives or exclusion criteria, but the tool's purpose is distinctive enough among the sibling list that an agent can infer when to select it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

disassembleB

Disassemble instructions at the given address or function, returning assembly with opcodes and metadata.

ParametersJSON Schema
NameRequiredDescriptionDefault
countNoNumber of instructions to disassemble (used with address mode)
addressNoHex address to disassemble at (e.g. "0x08048000")
binary_pathYesAbsolute path to the binary file
function_nameNoName of the function to disassemble (e.g. "main")

TDQS

B3.3/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the behavioral disclosure burden. It does state the output format at a high level ('returning assembly with opcodes and metadata'), but it does not explain what happens if both address and function_name are supplied, if neither is supplied, or if the target is invalid. This is adequate but not rich.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no filler. It front-loads the action and resource, then states the return value. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the moderate complexity of disassembly, no output schema, and no annotations, the description provides a reasonable overview but omits key operational details: how address mode and function mode interact, the role of count, and what 'metadata' includes. An agent could call it correctly in common cases but might mis-handle edge cases.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the parameter meanings are already fully documented in the schema. The description only echoes 'address or function' and adds no new semantic detail beyond the schema, meriting the baseline score of 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear verb ('Disassemble'), a specific resource ('instructions at the given address or function'), and the output ('assembly with opcodes and metadata'). It is distinguishable from siblings like decompile_function and disassemble_bytes, though it does not explicitly name them.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies two modes (address-based and function-based) but gives no guidance on when to prefer this tool over the closely related disassemble_bytes, which likely handles raw bytes. No exclusions or alternative routing is provided, leaving the agent to infer usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

disassemble_bytesA

Disassemble raw bytes into assembly instructions without loading a full binary.

ParametersJSON Schema
NameRequiredDescriptionDefault
bitsNoAddress size in bits32
offsetNoBase offset for the disassembly listing0x0
hex_bytesYesHex-encoded bytes to disassemble
architectureNoTarget architecturex86

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the behavioral disclosure burden. It does state that no full binary is loaded and that bytes are converted into assembly instructions, but it does not explicitly disclose read-only behavior, output format details, or error handling for invalid hex input.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence that is front-loaded with the core verb and resource, with no filler or redundant restatement. Every word contributes to understanding the tool's function.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with a fully documented input schema and a clear one-line functional statement, the description is largely complete. It lacks explicit output schema or return-value details, but the phrase 'into assembly instructions' conveys the expected result well enough for an agent to invoke and interpret the tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the parameters are already fully documented in the input schema. The description adds minimal semantic value beyond the schema, only framing the operation as acting on raw bytes, which aligns with hex_bytes.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Disassemble') with a clear resource ('raw bytes') and output ('assembly instructions'). The phrase 'without loading a full binary' distinguishes it from sibling tools like disassemble and analyze_binary, making the purpose unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Clearly conveys the intended context: use for raw bytes that are not part of a loaded binary. It does not explicitly name an alternative tool or state when not to use it, but the 'without loading a full binary' qualifier provides clear situational guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

esil_destroyA

Destroy a persistent ESIL session and release its resources. Use this when you are done with an emulation session.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idYesESIL session ID returned by esil_init

TDQS

A4.3/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden. It clearly discloses that destruction occurs and resources are released, which are the key behavioral consequences. It could add that this is irreversible, but 'destroy' strongly implies that.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences with no filler. The primary action is front-loaded, and the usage guidance follows immediately. Every word serves a purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter cleanup tool with no output schema, the description fully covers what the tool does, when to use it, and what happens. Nothing essential is missing for an agent to invoke it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the schema already explains that session_id is the ESIL session ID returned by esil_init. The description adds no additional parameter context, but the baseline of 3 is appropriate because the schema handles it fully.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Destroy'), a specific resource ('persistent ESIL session'), and the outcome ('release its resources'). This clearly distinguishes it from other session-related tools like esil_step or rzil_destroy.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly says when to use it: 'when you are done with an emulation session.' It does not discuss when not to use it or explicitly name alternatives, but the usage context is clear enough for this cleanup operation.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

esil_expressionB

Evaluate a raw ESIL expression string and return the result. If session_id is provided, uses a persistent session; otherwise creates a fresh session.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoAddress (hex) to set as program counter before evaluating the expression
expressionYesESIL expression to evaluate (postfix/RPN notation, e.g. "1,2,+")
session_idNoPersistent ESIL session ID from esil_init. If provided, binary_path and address are ignored.
binary_pathNoAbsolute path to the binary file. Required when session_id is not provided.

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden of behavioral disclosure. It discloses session behavior (persistent vs fresh) but fails to mention that evaluating an expression can mutate VM state, registers, or memory. It also does not describe the return format or whether side effects persist. This is a significant gap for an execution tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two short sentences with no filler. The core action is front-loaded, and the conditional session behavior is placed second. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the basic action and session selection, but it omits return-value details, side-effect warnings, and guidance on how this differs from esil_step or esil_run. Given no output schema and no annotations, the agent is left without important context needed to use the tool safely and correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description adds a bit of context about session_id and fresh-session creation, but this largely restates the schema's existing parameter descriptions rather than providing new meaning. It does not clarify address or expression format beyond what the schema already includes.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's function: evaluate a raw ESIL expression string and return the result. It uses a specific verb and resource, making it distinct from session-management and stepping tools in the sibling list, though it does not explicitly differentiate itself from esil_step or esil_run.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives conditional guidance about session usage: if session_id is provided, a persistent session is used; otherwise a fresh session is created. However, it does not state when to prefer this tool over esil_step/esil_run or other ESIL-related tools, leaving tool-selection context implicit.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

esil_get_memoryA

Read memory contents from the ESIL emulated memory space at a given address. If session_id is provided, uses a persistent session; otherwise creates a fresh session.

ParametersJSON Schema
NameRequiredDescriptionDefault
sizeNoNumber of bytes to read (default 64)
formatNoOutput format: "hex" (raw hex bytes), "string" (ASCII), or "hexdump" (classic hex dump)hex
addressYesAddress (hex) to read memory from
session_idNoPersistent ESIL session ID from esil_init. If provided, binary_path is ignored.
binary_pathNoAbsolute path to the binary file. Required when session_id is not provided.

TDQS

A4.1/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the transparency burden. It discloses the main side effect: creating a fresh session when session_id is absent. However, it does not mention session cleanup (e.g., esil_destroy), error behavior for invalid addresses/sessions, or the implications of leaving a fresh session active.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no filler. The core read action is front-loaded, and the session logic is stated compactly without redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a moderate-complexity tool with no output schema and no annotations, the description covers the primary action and session choice, but omits cleanup obligations, failure behavior, and return value specifics. It is adequate but not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, giving a baseline of 3. The description adds value by explaining the behavioral difference: using a persistent session versus creating a fresh one, which goes beyond the schema's note that binary_path is ignored when session_id is provided.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb and resource: 'Read memory contents from the ESIL emulated memory space at a given address.' It clearly distinguishes this from debug memory reads and RZIL variants by naming the ESIL emulated space, and it also communicates the session behavior.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear conditional guidance: use a persistent session when session_id is supplied, and otherwise a fresh session is created. It does not explicitly name alternative tools or exclusions, but the session usage context is sufficiently clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

esil_get_registersA

Read all register values or a specific register from the ESIL virtual machine state. If session_id is provided, uses a persistent session; otherwise creates a fresh session.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoAddress (hex) to set as program counter before reading registers
session_idNoPersistent ESIL session ID from esil_init. If provided, binary_path and address are ignored.
binary_pathNoAbsolute path to the binary file. Required when session_id is not provided.
register_nameNoSpecific register name to read (e.g. "eax", "rip"). If omitted, all registers are returned.

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the transparency burden. It discloses that a fresh session may be created and that a persistent session is used when session_id is provided, which is useful. However, it does not mention that setting address modifies the program counter, nor does it describe any session lifecycle or cleanup behavior, leaving some behavioral gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences with no filler. It front-loads the core action and follows with the session-mode behavior. Every sentence contributes useful information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a getter with 100% schema coverage, the description plus schema provides enough to invoke the tool correctly: what it reads, how session_id changes behavior, and the required binary_path when no session exists. It lacks explicit return format and ignores the address-as-PC effect, but these are secondary given the schema already documents the address parameter.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description adds a small amount of context around session_id versus fresh session creation, but it does not meaningfully add semantic value beyond what the schema already documents for the parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb and resource: 'Read all register values or a specific register from the ESIL virtual machine state.' The ESIL scope clearly differentiates it from sibling tools like debug_get_registers and rzil_get_registers, and the all-or-specific distinction makes the tool's purpose unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context on when to use a persistent session versus a fresh one: 'If session_id is provided, uses a persistent session; otherwise creates a fresh session.' This helps an agent choose the right invocation path, though it does not explicitly mention alternatives or when not to use the tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

esil_initA

Initialize the ESIL virtual machine with stack memory and return a persistent session_id for subsequent ESIL tool calls. The session preserves ESIL state (registers, memory, PC) across calls.

ParametersJSON Schema

addressNoStart address (hex). If omitted, entry point is used.
stack_sizeNoESIL stack size in bytes (default 0x100000)
binary_pathYesAbsolute path to the binary file
stack_addressNoESIL stack base address (default "0x00100000")0x00100000

A3.6/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full disclosure burden and does add real value: it allocates stack memory, returns a session_id, and states that registers/memory/PC persist across calls. However, it omits the resource-lifecycle trait — sessions persist and accumulate and should eventually be cleaned up via esil_destroy — which is a relevant behavioral disclosure for an init tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with zero wasted words. The main action and return value are front-loaded in the first sentence, and the second sentence earns its place by explaining the persistence semantics that matter for all downstream ESIL calls.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema and no annotations, the description covers the essential contract: what is initialized, what is returned (session_id), and that state persists across calls. The remaining gaps — cleanup obligation (esil_destroy) and error behavior for invalid binary paths — are notable but the core call sequence is fully understandable.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all four parameters are already documented with defaults, hex formats, and minimums. The description's 'with stack memory' loosely contextualizes stack_size/stack_address and 'binary' maps to binary_path, but it adds no meaning beyond the schema — baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Initialize'), identifies the resource ('ESIL virtual machine'), and states the key output ('persistent session_id'). It clearly separates this from the rzil_* family by naming 'ESIL' specifically and from debug_launch by describing the emulation session model, though it doesn't explicitly name those alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'for subsequent ESIL tool calls' implies this is the entry point for the ESIL family and must be called before esil_step, esil_run, esil_get_registers, etc. However, it never explicitly states when to prefer ESIL over RZIL (rzil_init) or debug_launch, and provides no exclusion criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

esil_list_sessionsA

List all active persistent ESIL sessions with their session IDs, binary paths, and creation times.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A4.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of disclosure. It clearly describes a read-only listing operation and states the returned data fields (session IDs, binary paths, creation times), which is meaningful behavioral context. It does not explicitly state side-effect-free behavior, but 'List' naturally implies no mutation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is one concise sentence that leads with the action and resource, then lists the relevant output fields. Every word adds value and there is no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple zero-parameter list operation, the description is largely complete: it states the resource scope and the return fields despite the lack of an output schema. It could have clarified what 'persistent' means or how the result relates to esil_init-created sessions, but these are minor gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters and the schema is empty, so the baseline is 4. There are no parameters for the description to explain, and the schema coverage is complete.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('List') and resource ('active persistent ESIL sessions'), and specifies the output fields. It clearly identifies what the tool does and distinguishes it from debug_list_sessions and rzil_list_sessions by naming the ESIL session concept.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use the tool: when you need current active persistent ESIL sessions. However, it does not explicitly state when to prefer this over sibling tools like esil_init, rzil_list_sessions, or debug_list_sessions, nor does it mention any exclusions or prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

esil_runA

Run ESIL emulation until a target address is reached, a breakpoint is hit, or maximum steps are exceeded. If session_id is provided, uses a persistent session; otherwise creates a fresh session.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoStart address (hex) for emulation. If omitted, entry point is used.
timeoutNoMaximum time in seconds before stopping emulation (default 30)
max_stepsNoMaximum number of steps before stopping (default 1000)
session_idNoPersistent ESIL session ID from esil_init. If provided, binary_path and address are ignored.
binary_pathNoAbsolute path to the binary file. Required when session_id is not provided.
until_addressNoStop emulation when this address is reached (hex)

TDQS

A4.1/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the behavioral disclosure burden. It discloses the stopping conditions and the session reuse/fresh-session behavior, which goes beyond the schema. It does not mention side effects on the persistent session or error/return behavior, but the core execution behavior is transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two tightly written sentences. The primary behavior and termination conditions are front-loaded, and the session rule is stated without wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 6-parameter emulation tool with no annotations and no output schema, the description covers the core execution semantics but omits return value behavior, how breakpoints interact with the session, and an explicit distinction from rzil_run. The rich schema and sibling context help, but some important operational context is still missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already documents all 6 parameters with descriptions, so the baseline is 3. The description reinforces session_id semantics and stopping conditions but adds no new format or relationship details beyond what the schema already states.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('Run ESIL emulation'), the resource, and the exact termination conditions (target address, breakpoint, max steps). This clearly distinguishes it from siblings like esil_step (single-step) and esil_init (session setup), so an agent can tell what this tool does.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives explicit session guidance: use a persistent session when session_id is provided, otherwise create a fresh session. It does not explicitly compare against rzil_run or esil_step, but the context is clear enough for basic tool selection among the emulation siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

esil_set_memoryA

Write data to the ESIL emulated memory space at a given address. If session_id is provided, uses a persistent session; otherwise creates a fresh session.

ParametersJSON Schema
NameRequiredDescriptionDefault
dataYesData to write: hex bytes (e.g. "90909090") or a string if as_string is true
addressYesAddress (hex) to write memory to
as_stringNoIf true, write data as an ASCII string; otherwise write as raw hex bytes
session_idNoPersistent ESIL session ID from esil_init. If provided, binary_path is ignored.
binary_pathNoAbsolute path to the binary file. Required when session_id is not provided.

TDQS

A3.8/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description carries the behavioral disclosure burden. It does disclose the core mutation target (ESIL emulated memory) and the persistent-vs-fresh session behavior, which is useful context beyond the name. It does not mention return/error behavior or what creating a fresh session fully entails, but the primary side effect is stated.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One compact sentence placed the core operation first and the relevant session conditional second. There is no filler, no restating of schema fields, and every clause adds value toward correct invocation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With a fully covered schema and no output schema, the description covers the main invocation decision: persistent session vs fresh session. It could additionally mention that binary_path is required when session_id is absent and describe the return value, but those are either present in the schema or non-critical for a write operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents address, data, as_string, session_id, and binary_path. The description adds minimal extra meaning, mostly reiterating the session_id behavior already present in the schema; it does not materially clarify as_string or binary_path beyond their schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Write'), a clear resource ('ESIL emulated memory space'), and an argument ('at a given address'). The 'ESIL emulated' qualifier distinguishes it from sibling memory-write tools like debug_write_memory, write_bytes, and rzil_set_memory.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The session_id conditional is clearly explained: use a persistent session when session_id is provided, otherwise a fresh session is created. However, the description never names or contrasts alternatives such as debug_write_memory or rzil_set_memory, so an agent gets no explicit guidance on which sibling tool to choose.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

esil_set_registerA

Set a register value in the ESIL virtual machine. If session_id is provided, uses a persistent session; otherwise creates a fresh session.

ParametersJSON Schema
NameRequiredDescriptionDefault
valueYesValue to set the register to (hex string, e.g. "0x41414141")
addressNoAddress (hex) to set as program counter before modifying registers
session_idNoPersistent ESIL session ID from esil_init. If provided, binary_path and address are ignored.
binary_pathNoAbsolute path to the binary file. Required when session_id is not provided.
register_nameYesRegister name to set (e.g. "eax", "rip", "rsp")

TDQS

A3.9/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the behavioral disclosure burden. It discloses the persistent vs. fresh session behavior, which is valuable, but it does not mention side effects, return behavior, or what happens to the fresh session after the call.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences with no filler. The core action is front-loaded, followed by the conditional session behavior. Every sentence adds useful information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The schema already documents the parameters, and the description explains the session-mode distinction. However, with no output schema and no annotations, the description omits return semantics and the lifecycle of a freshly created session, which an agent would need for confident invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds meaning beyond the schema by clarifying what happens when session_id is absent: a fresh session is created. This supplements the schema's 'binary_path is required' hint with the actual session-creation behavior.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action and resource: setting a register value in the ESIL virtual machine. The explicit ESIL wording distinguishes it from sibling tools like debug_set_register and rzil_set_register, which target different execution contexts.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives a useful internal condition for session_id: persistent session if provided, fresh session otherwise. However, it does not explicitly compare this tool to alternatives such as debug_set_register or rzil_set_register, so when-to-use versus those siblings is left implied.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

esil_stepB

Execute one or more instruction steps in the ESIL emulator and return the updated register state. If session_id is provided, uses a persistent session; otherwise creates a fresh session.

ParametersJSON Schema
NameRequiredDescriptionDefault
countNoNumber of steps to execute (default 1)
addressNoStart address (hex) for emulation. If omitted, entry point is used.
step_overNoIf true, use step-over (aeso) instead of step-into (aes)
session_idNoPersistent ESIL session ID from esil_init. If provided, binary_path and address are ignored.
binary_pathNoAbsolute path to the binary file. Required when session_id is not provided.

TDQS

B3.3/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the behavioral disclosure burden, and it does add useful context: the tool steps instructions, returns updated registers, and reuses or creates a session based on session_id. However, it omits side effects on emulator/session state, cleanup behavior, and what happens when required inputs are missing.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, front-loaded with the core action and result, and the second sentence covers the central session distinction. There is no filler or redundant repetition of schema details.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 5 parameters and no output schema or annotations, this is minimally adequate: it states the action, result, and the session branch. It does not describe the structure of the returned register state, prerequisites for a fresh session, or how stepping differs from esil_run and rzil_step.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description adds one relationship not fully captured in the schema—session_id overriding other session context—but it does not enrich count, address, step_over, or binary_path beyond their schema text.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'Execute one or more instruction steps in the ESIL emulator' and names the observable result, updated register state. It is not a tautology and is clearly distinct from the debug and analysis tools, though it does not explicitly contrast with near-siblings like esil_run or rzil_step.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The only usage direction is the session_id conditional ('uses a persistent session; otherwise creates a fresh session'), which tells how the tool behaves but not when to prefer it over alternatives. There is no mention of esil_run, debug_step, rzil_step, or prerequisites such as needing esil_init first.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

exploit_hunterB

Exploit development assistant: analyze security mitigations, find dangerous functions, collect ROP gadgets, map input sources, and suggest exploitation strategies.

ParametersJSON Schema
NameRequiredDescriptionDefault
binary_pathYesAbsolute path to the binary file
gadget_searchNoROP gadget search depth: none=skip, basic=common gadgets, full=comprehensivebasic
target_functionNoSpecific function to analyze for exploitability

TDQS

B3.1/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the burden of explaining behavior. It does convey an analysis-oriented behavior via verbs like analyze, find, collect, map, and suggest, rather than a mutating operation. However, it does not disclose side effects, runtime/resource costs, whether the binary is executed, or what form the output takes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence beginning with the tool's role and then listing its capabilities. It is efficient and free of filler, though a second sentence clarifying output or usage would improve utility without sacrificing conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a complex multi-stage tool with no output schema and no annotations, yet the description gives no indication of what the tool returns, how comprehensive or expensive the analysis is, or how it differs from nearby analysis siblings. An agent invoking it would lack essential context about the result and scope of the operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already documents all three parameters with 100% coverage, including the gadget_search enum and default and target_function's purpose. The description adds little semantic detail beyond the schema, so it meets the baseline without exceeding it.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear role: an exploit development assistant that analyzes mitigations, finds dangerous functions, collects ROP gadgets, maps input sources, and suggests strategies. It is clear what the tool does, but it does not distinguish itself from overlapping siblings like find_vulnerabilities, triage_binary, and search_rop_gadgets, so it falls short of full differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus its many overlapping alternatives, and no when-not-to-use conditions are given. The phrase 'exploit development assistant' only vaguely implies an exploit-development context; given the large sibling set, an agent cannot reliably determine when this tool should be preferred.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

extract_iocsB

Extract Indicators of Compromise from a binary: IP addresses, URLs, domains, file paths, registry keys, email addresses, crypto wallets, and embedded payloads.

ParametersJSON Schema
NameRequiredDescriptionDefault
binary_pathYesAbsolute path to the binary file
scan_all_bytesNoSearch all bytes (slower) vs only data sections
include_contextNoInclude xref context for each IOC

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not state whether the operation is read-only, how performance is affected by scan_all_bytes, whether embedded payloads are extracted to disk, or what the output structure looks like. This is a meaningful gap for a tool that can potentially scan large binaries.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence that states the verb, resource, and deliverable in a compact list. Every word earns its place, and the IOC type enumeration is scannable and informative without being verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has no output schema and no annotations, so the description alone must orient the agent. It does well by naming the expected IOC categories, but it omits practical context such as default scanning behavior, output format, or potential side effects. This is enough for confident tool selection but not full invocation clarity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the parameters (binary_path, scan_all_bytes, include_context) are already documented. The tool description adds no parameter-specific meaning beyond the schema, which is acceptable given the high schema coverage baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Extract') and resource ('binary'), and enumerates concrete IOC types (IP addresses, URLs, domains, etc.), making the tool's purpose unmistakable. It is clearly distinguishable from siblings like list_strings or find_crypto_constants, which focus on different kinds of binary analysis.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. Sibling tools such as list_strings, search_strings, and find_crypto_constants overlap in the broad space of binary analysis, but the description does not mention any when/when-not conditions or alternative tools, leaving the selection entirely to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

file_format_analyzerA

Analyze binary file format structures: identify format via magic bytes, parse containers (RIFF/WebP, PNG, ZIP, JPEG, PDF), and show chunk hierarchy with offsets, sizes, and metadata.

ParametersJSON Schema
NameRequiredDescriptionDefault
file_pathYesPath to the file to analyze
max_chunksNoMaximum number of chunks/sections to parse
hexdump_sizeNoBytes to hexdump from each chunk header (0 to disable)

TDQS

A4.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full behavioral burden. It clearly states the analysis pipeline: identify format, parse containers, and expose chunk hierarchy with offsets, sizes, and metadata. The read-only nature of 'analyze' is strongly implied, covering the main safety concern for an agent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence packs the purpose, scope, supported container types, and output format without redundancy. It is front-loaded with the action and resource, and every phrase contributes to tool selection and invocation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only analysis tool with no output schema, the description sufficiently describes what the agent can expect to see (offsets, sizes, metadata). It does not mention behavior on unrecognized formats or error conditions, but the core invocation context is complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents all three parameters, including defaults and bounds. The description adds minimal parameter-specific meaning beyond hinting at chunk and offset output, which maps naturally to max_chunks and hexdump_size. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource ('Analyze binary file format structures') and immediately enumerates concrete deliverables: magic-byte identification, container parsing (RIFF/WebP, PNG, ZIP, JPEG, PDF), and chunk hierarchy with offsets, sizes, and metadata. This clearly distinguishes it from generic siblings like analyze_binary or binary_headers.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context for when to use the tool: whenever the task involves recognizing a file format or inspecting container/chunk structure. It does not explicitly name alternatives or state when not to use it, but the specificity of the listed containers and output makes the intended usage obvious.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

find_constraintsA

Extract comparisons, conditional branches, string references, and success/fail paths from a function — ideal for crackme and CTF challenge analysis.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoHex address of the function (e.g. "0x08048000")
binary_pathYesAbsolute path to the binary file
scan_calleesNoAlso scan functions called from this function for constraints
function_nameNoName of the function to analyze (e.g. "main")

TDQS

A4.1/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the behavioral disclosure burden. The verb 'Extract' communicates a read-only, non-mutating operation, and the description transparently lists what the tool will look for: comparisons, branches, string references, and success/fail paths. It stops short of describing output formatting or traversal behavior, but the core behavior is clear.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, tight sentence that front-loads the tool's primary behavior and output categories, then adds the relevant use case. Every word earns its place and there is no redundancy or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and no annotations, the description should compensate by explaining the result shape and any important selection constraints. It names the extracted artifacts but does not say how results are returned, nor does it address how function selection works when address and function_name are both absent (only binary_path is required). The schema fills in parameter details, but the overall invocation context has notable gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the input schema already fully documents all four parameters. The description adds no additional parameter-level meaning; it only reinforces that the tool works on 'a function,' which maps to address or function_name but adds nothing beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses the specific verb 'Extract' with a concrete resource ('from a function') and enumerates the exact output categories: comparisons, conditional branches, string references, and success/fail paths. This clearly separates it from generic siblings like disassemble or decompile_function, and even from analyze_function_deep, by focusing specifically on constraint-related artifacts.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'Ideal for crackme and CTF challenge analysis' provides a clear, explicit context for when this tool is appropriate. It does not explicitly name alternatives or state when not to use it, but the use case guidance is strong enough to route an agent correctly in most situations.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

find_crypto_constantsA

Detect cryptographic constants (AES S-boxes, CRC tables, RSA constants, SHA magic numbers) in the binary.

ParametersJSON Schema
NameRequiredDescriptionDefault
binary_pathYesAbsolute path to the binary file

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description carries the behavioral disclosure burden. The verb 'detect' implies a non-mutating scan, but the description does not disclose output format, whether detection is heuristic, possible false positives, or limitations with packed or obfuscated binaries. It provides basic transparency but not rich detail.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single focused sentence with the action front-loaded and concrete examples following. There is no filler, redundancy, or unnecessary detail, making it efficient for an agent to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The invocation context is clear for a single-parameter tool, and sibling names do not create ambiguity about the core purpose. However, with no output schema and no mention of return value structure, scan scope, or result presentation, the description is not fully complete for an agent trying to use the tool end-to-end.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The only parameter, binary_path, is fully described in the schema with its type and meaning ('Absolute path to the binary file'), resulting in 100% schema description coverage. The tool description adds no additional parameter semantics, so the baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific action ('Detect') and a specific target ('cryptographic constants'), reinforced with concrete examples like AES S-boxes, CRC tables, RSA constants, and SHA magic numbers. This makes the tool's purpose unambiguous and distinguishable from sibling analysis and search tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies this tool should be used when looking for cryptographic constants in a binary, but it does not explicitly say when to prefer it over alternatives such as search_bytes or list_strings. No exclusions or alternative tool references are provided, leaving some selection burden on the agent.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

find_vulnerabilitiesC

Scan a binary for common vulnerability patterns: dangerous API usage, buffer overflows, format strings, integer overflows, and missing bounds checks.

ParametersJSON Schema
NameRequiredDescriptionDefault
scan_depthNoAnalysis depth: quick=imports only, standard=imports+xrefs, deep=imports+xrefs+decompilestandard
binary_pathYesAbsolute path to the binary file

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It says 'scan' and lists patterns, but does not explain whether the scan is static or dynamic, whether it executes the binary, what side effects may occur, how long it might take, or what kind of output is produced.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence that front-loads the primary action and resource before listing specific vulnerability classes. It contains no filler, though the long pattern list could have been slightly condensed without losing value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no output schema, the description should explain what the tool returns or how the results are presented. This description only states what it scans for, not what the agent should expect afterward. It also does not address how it relates to exploit_hunter or whether findings are reported as a list, report, or severity-ranked results.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the input schema already documents binary_path and scan_depth, including the enum semantics for scan_depth. The description adds no additional parameter detail, so the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific action ('scan') on a specific resource ('a binary') and enumerates concrete vulnerability patterns it checks for. It does not explicitly distinguish itself from nearby siblings like exploit_hunter, but the pattern list gives enough specificity for basic differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided about when this tool should be used versus alternatives such as exploit_hunter, analyze_binary, or triage_binary. The context implies it is the natural choice for vulnerability scanning, but no explicit selection criteria or exclusions are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_callgraphC

Get the call graph for a function showing all callers and callees as a structured graph.

ParametersJSON Schema
NameRequiredDescriptionDefault
depthNoMaximum recursion depth for the call graph (default: unlimited)
formatNoOutput format for the call graphjson
addressNoHex address of the function (e.g. "0x08048000")
binary_pathYesAbsolute path to the binary file
function_nameNoName of the function (e.g. "main")

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, so the description carries the full behavioral disclosure burden. It states the high-level output but does not disclose recursion behavior, whether depth defaults to unlimited, error handling for missing functions, or any side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single front-loaded sentence with no filler. It efficiently states the main purpose without wasting tokens.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no annotations and no output schema, the description leaves critical gaps: it does not explain how to select the target function when both address and function_name are optional, does not describe the graph structure, and does not disambiguate from the closely related get_control_flow_graph sibling.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents each parameter. The description adds no real semantic value about how address vs function_name relate, or how depth and format interact with the graph.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear verb ('Get') and resource ('call graph for a function'), and clarifies the content as callers and callees. However, it does not explicitly distinguish itself from the sibling tool 'get_control_flow_graph', which could cause confusion.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternatives such as get_control_flow_graph, get_xrefs, or trace_execution. The description also does not mention whether the caller should provide an address, a function name, or both.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_control_flow_graphB

Get the control flow graph of a function as a JSON structure with basic blocks and edges.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoHex address of the function (e.g. "0x08048000")
binary_pathYesAbsolute path to the binary file
function_nameNoName of the function (e.g. "main")

TDQS

B3.2/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses the return shape—JSON with basic blocks and edges—which is useful given there is no output schema. However, with no annotations, it does not explain read-only behavior, precedence rules when both address and function_name are supplied, or failure cases such as an unresolved function.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, focused sentence that immediately conveys the operation and output format. It contains no filler and is appropriately front-loaded with the primary purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no annotations and no output schema, the description leaves important context missing: how to select a function via address versus name, which parameter is required in practice, and how this relates to alternative analysis tools. The core purpose is clear, but an agent lacks enough information to invoke it correctly in ambiguous cases.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all three parameters. The description adds no additional meaning to address, binary_path, or function_name, and does not explain the relationship or mutual exclusivity between the two optional function identifiers.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear verb and resource: it gets the control flow graph of a function. It also distinguishes itself from sibling get_callgraph by scoping to a function's CFG rather than a call graph. However, it does not explicitly differentiate itself from nearby function-analysis tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided about when to use this tool versus alternatives such as get_callgraph, disassemble, decompile_function, or analyze_function_deep. It also fails to clarify whether callers should provide address, function_name, or both, which is essential for correct usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_entropyB

Calculate entropy for the binary or specific sections to detect packed or encrypted regions.

ParametersJSON Schema
NameRequiredDescriptionDefault
sizeNoNumber of bytes to analyze for entropy
addressNoStart address for entropy calculation (hex)
binary_pathYesAbsolute path to the binary file

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

There are no annotations, so the description carries the full burden of behavioral disclosure. It only states that entropy is calculated, but does not disclose the return format, whether it is purely read-only, what range the entropy value has, or whether it requires an already-loaded binary session. This is a significant gap for a tool with no annotation metadata.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence that front-loads the core action and purpose. There is no wasted phrasing, though the meaning of 'specific sections' could have been made clearer without much additional length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that there is no output schema and no annotations, the description should explain return values and key behavioral context. It also fails to specify default behavior when size or address is omitted, which is critical for an agent to invoke the tool correctly. The description is adequate for grasping the general purpose but not sufficient for correct independent invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the parameters are already documented for binary_path, address, and size. The description adds the general concept of 'binary or specific sections' but does not clarify how address and size interact, what happens when they are omitted, or how they relate to section-based entropy calculation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Calculate entropy') and the target resource ('the binary or specific sections'), plus the purpose of detecting packed or encrypted regions. It is not a tautology and gives an agent a concrete idea of the tool's role, though 'specific sections' is somewhat ambiguous and does not explicitly differentiate it from sibling analysis tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use the tool: when you suspect packing or encryption and want to measure entropy. However, it provides no explicit guidance on when not to use it, nor does it mention alternative tools like analyze_binary or find_crypto_constants that could also be relevant.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_function_infoA

Get detailed metadata for a single function including cyclomatic complexity, stack frame, args, locals, and basic block count.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoHex address of the function (e.g. "0x08048000")
binary_pathYesAbsolute path to the binary file
function_nameNoName of the function (e.g. "main")

TDQS

A3.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden of conveying behavior. It clearly signals a read-only metadata operation via 'Get' and lists the kinds of data the agent can expect. It does not mention error cases or behavior when multiple selectors are provided, but the core behavioral traits are transparent and non-destructive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, tightly written sentence with no filler. The core action and scope are front-loaded, and the metadata list is concise yet informative.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description gives a useful preview of return contents, which partially compensates for the absence of an output schema. However, it does not explain how the target function is selected when address and function_name are both optional, nor does it describe the full output shape. An agent may attempt a call with only binary_path and be unable to resolve which function to inspect.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents address, binary_path, and function_name. The description adds no parameter-level meaning beyond the schema and does not clarify that binary_path alone may be insufficient to identify a single function. This keeps it at the baseline for high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Get') and the resource ('detailed metadata for a single function'), and it enumerates specific metadata fields such as cyclomatic complexity, stack frame, args, locals, and basic block count. It is clear enough to separate from list_functions, though it does not explicitly distinguish itself from analyze_function_deep.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given about when to choose this tool over alternatives like list_functions, analyze_function_deep, or get_control_flow_graph. There are no exclusions, prerequisites, or conditions stated. The description simply states what the tool does without advising on selection.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_xrefsA

Get all cross-references to or from a specific address, identifying callers, callees, and data references.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
offsetNoPagination offset (0-based)
addressYesHex address (e.g. "0x08048000")
directionNoDirection of cross-references: "to" (who references this) or "from" (what this references)to
binary_pathYesAbsolute path to the binary file

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It correctly implies a read-only query and describes the categories of results, but it does not disclose pagination behavior or the fact that the default limit may prevent returning truly 'all' cross-references, making the word 'all' slightly misleading.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single, front-loaded sentence with no filler. It begins with the verb and object, then adds the key output categories. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description combined with the fully described schema gives the agent enough to invoke the tool correctly (required binary_path and address, optional limit/offset/direction). The lack of an output schema is partially mitigated by the description's mention of callers/callees/data references, though a brief note on return structure would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 100% schema coverage, the baseline is 3. The description adds meaning beyond the schema by translating the direction enum into concrete output categories ('callers, callees, and data references'), giving the agent a richer understanding of what the address and direction parameters produce.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Get') and a precise object ('cross-references to or from a specific address') while clarifying what the results identify ('callers, callees, and data references'). This clearly distinguishes the tool from sibling graph/analysis tools such as get_callgraph or get_control_flow_graph.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies its use case: when an agent needs address-level cross-references, this is the tool. However, it provides no explicit when-to-use or when-not-to-use guidance, nor does it name alternatives or exclusions, leaving some interpretation to the agent.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

hash_binaryA

Compute cryptographic hashes of the binary or a specific address range.

ParametersJSON Schema
NameRequiredDescriptionDefault
sizeNoNumber of bytes to hash from address
addressNoStart address for range hash (requires size)
algorithmNoHash algorithm to usesha256
binary_pathYesAbsolute path to the binary file

TDQS

A3.9/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must carry the behavioral burden. It accurately conveys a read-only computation over the binary or a range, but it does not disclose output format, the default behavior when no address/size is provided, or algorithm default behavior. These are not contradictions, but they are notable gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single front-loaded sentence with no filler. It names both supported modes in a compact form, making it easy for an agent to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is adequate for a simple hash tool but leaves some behavior unspecified: whether hashing the whole binary is the default, whether range hashing requires both address and size, and what the return value looks like. The schema covers parameter semantics, but the absence of an output schema and annotations makes these gaps more significant.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the parameters are already well documented. The description adds only the general 'binary or address range' idea, which maps to binary_path and address/size but does not add meaning beyond the schema's own descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Compute') and a clear resource ('cryptographic hashes of the binary') while also identifying the optional address-range scope. This distinguishes it from siblings like read_bytes, get_entropy, and analyze_binary, which perform different operations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clearly conveys the intended use: computing hashes for either a whole binary or a specific address range. It does not name alternatives or exclusions, but the operation is narrow enough that an agent can infer when to select this tool; no misleading guidance is present.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_classesA

List classes and their methods from C++, Objective-C, Java, or Swift binaries.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
offsetNoPagination offset (0-based)
binary_pathYesAbsolute path to the binary file

TDQS

A3.8/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the burden of explaining behavior. It communicates a read-only listing operation and restricts scope to four binary language families, but it does not mention failure modes, dependencies, or whether prior analysis is required.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is one concise sentence with no filler. It front-loads the action, resource, and scope, and every word contributes to the tool's meaning.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one required parameter and a clear listing goal, the description covers the essential selection criteria and output domain. Explicitly noting output structure or the boundary with list_functions would improve completeness, but the current definition is sufficient for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all parameters are already documented with clear meanings: binary_path, limit, and offset. The description adds no extra parameter context, so the baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names the exact resource: classes and their methods, and specifies the supported source languages: C++, Objective-C, Java, or Swift. This clearly distinguishes it from sibling tools like list_functions or list_imports.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the use case: use this tool when class/method information is needed from supported binary types. However, it does not explicitly compare against alternatives such as list_functions or state when not to use this tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_exportsB

List all exported functions and symbols with their addresses and types.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
offsetNoPagination offset (0-based)
binary_pathYesAbsolute path to the binary file

TDQS

B3.4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the behavioral transparency burden. The verb 'List' strongly implies a read-only operation and the description discloses what is returned, but it does not clarify that 'all' may be constrained by the limit/offset pagination parameters, nor does it mention whether the binary must already be loaded or analyzed. It is acceptable but not richly transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence with no filler. It communicates the core purpose and output details efficiently without wasting words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a straightforward listing tool with a required binary_path and optional pagination parameters, the description adequately conveys what the tool does and what information it returns. There is no output schema, but 'addresses and types' gives a sufficient hint at the result shape. The main gap is the lack of differentiation from related listing tools, which is more a usage-guidance issue than a completeness issue.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already explains binary_path, limit, and offset effectively. The description adds no extra parameter context beyond the overall tool purpose, which matches the baseline score of 3 for high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('List') and the resource ('all exported functions and symbols'), and specifies the returned data ('addresses and types'). It is understandable and specific, though it does not explicitly differentiate itself from sibling tools like list_functions or list_imports.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives such as list_imports, list_functions, or rz_symbols. There are no exclusions, prerequisites, or conditions stated, so an agent must infer the appropriate context from the name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_functionsA

List all functions identified by radare2 analysis with their names, addresses, sizes, and call conventions.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
filterNoOptional substring to filter function names
offsetNoPagination offset (0-based)
sort_byNoSort functions by address, size, or nameaddress
binary_pathYesAbsolute path to the binary file

TDQS

A3.5/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the burden of behavioral disclosure. It adds useful context by stating that results come from radare2 analysis, implying the function depends on prior analysis rather than performing it directly, and it describes what output fields to expect. However, it does not explicitly state that the operation is read-only, whether analysis must already have been run, or what happens if the binary has not been analyzed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that immediately states the action, scope, and returned information without any filler. Every word contributes meaningful information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the core listing purpose and output fields, and the schema fully documents the parameters. However, with no output schema and no annotations, an agent still lacks guidance on prerequisites (e.g., whether the binary must first be analyzed with analyze_binary), how results are returned, and when list_functions is preferable to related tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all five parameters are already documented with descriptions, defaults, and constraints. The description adds no extra parameter-level meaning beyond restating the output fields, so the baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('List') with a clear resource ('all functions identified by radare2 analysis') and enumerates the returned attributes: names, addresses, sizes, and call conventions. This clearly distinguishes it from sibling tools like get_function_info, which targets a single function, and list_imports, which targets a different entity type.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no explicit guidance on when to use this tool versus alternatives such as get_function_info, list_exports, or analyze_binary. The intended use is only implied by the function name and the listing semantics, but no conditions, exclusions, or alternative routing are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_importsA

List all imported functions and symbols with their addresses and library origins.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
offsetNoPagination offset (0-based)
binary_pathYesAbsolute path to the binary file

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full transparency burden. The verb 'List' conveys a read-only, non-destructive operation and the output content is disclosed, but the description does not address prerequisites (e.g., whether the binary must first be loaded or analyzed given siblings like analyze_binary) or empty-result behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single 13-word sentence with zero filler; the verb, resource, and key output detail are all front-loaded. Every word contributes meaning and nothing is redundant.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple 3-parameter listing tool, the description plus schema adequately covers inputs and stated outputs. However, with no output schema, no annotations, and no mention of preconditions or when to prefer this over sibling listing tools, an agent is left to infer those details.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all three parameters (binary_path, limit, offset) are already documented with types, defaults, and bounds. The description adds no parameter-level detail beyond the schema, matching the baseline of 3 for high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb ('List') and names a precise resource ('imported functions and symbols') along with the key output fields ('addresses and library origins'). This inherently distinguishes it from siblings like list_exports, list_functions, and list_variables, so an agent can select the correct tool without inspecting the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit when-to-use guidance or alternative routing is provided; the description never mentions list_exports, list_functions, or the dependency-analysis context where import inspection matters. The intended use is only implied by the tool's name and purpose statement.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_relocationsB

List all relocations in the binary with their addresses, types, and target symbols.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
offsetNoPagination offset (0-based)
binary_pathYesAbsolute path to the binary file

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

There are no annotations, so the description must fully convey read behavior. The verb 'List' implies a read-only operation, but the phrase 'all relocations' conflicts with the schema's default limit of 100, and the description does not disclose pagination/truncation behavior or what happens on an invalid binary path.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single, front-loaded sentence with no filler. It communicates the operation, resource, and primary returned data efficiently.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description usefully names the return fields, but it omits important invocation context: the default limit means 'all' is not returned by default, and the relationship between pagination parameters and full enumeration is left to the schema. For a simple read-only list tool this is close to adequate but not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline applies; the schema already explains binary_path, limit, and offset. The description adds no parameter-level detail, but it does not need to given the complete schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb ('List') and a specific resource ('relocations in the binary'), and specifies the returned fields: addresses, types, and target symbols. It is unambiguous and clearly separated from sibling listing tools by resource type, though it does not explicitly contrast itself with list_imports/list_exports.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The intended use is implied: call this when relocation information is needed for a binary. However, the description gives no explicit when-to-use guidance, no prerequisites, and no alternatives or exclusions, leaving the agent to infer routing from the resource name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_resourcesA

List PE resources (icons, manifests, version info, embedded data) from the binary.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
offsetNoPagination offset (0-based)
binary_pathYesAbsolute path to the binary file

TDQS

A3.5/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the behavioral burden. 'List' implies a read-only operation, and the resource-category examples give some insight, but the description does not disclose behavior on non-PE binaries, error cases, or result shape. It does not contradict any annotations because none exist.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, compact sentence that front-loads the action and object. Every word adds value, and there is no repetition of schema information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and no annotations, the description should provide more context about what the agent can expect in the returned list. It clearly identifies the resource categories but does not describe the structure of returned items or error behavior. This is acceptable for a simple listing tool but not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already documents all three parameters with descriptions, including binary_path meaning and limit/offset pagination defaults. The description adds no parameter-specific semantics beyond the PE-resource context, so the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('List') and resource ('PE resources') with helpful examples (icons, manifests, version info, embedded data). This clearly distinguishes it from sibling list_* tools such as list_imports, list_exports, and list_sections.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance about when to use this tool versus alternatives, no exclusions, and no mention of prerequisites. The only contextual hint is 'PE resources,' which implies a Windows PE focus but does not help an agent decide among the many listing tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_sectionsA

List all sections and segments in the binary with addresses, sizes, and permissions.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
offsetNoPagination offset (0-based)
binary_pathYesAbsolute path to the binary file

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It discloses that this is a read-only listing operation and hints at return content, but it does not address pagination behavior, ordering, address formatting, or the apparent tension between 'all' and the limit/offset parameters. The core behavior is clear, but edge behavior is not.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence with no filler words. It communicates the resource, operation, and key output attributes efficiently.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple listing tool with no output schema and no annotations, the description is minimally adequate: it names the target and the returned attributes. However, it omits important context like pagination semantics, whether all results require multiple calls, and what happens with invalid or unanalyzable binaries, so it is not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already fully explains binary_path, limit, and offset. The description does not add input parameter semantics beyond what the schema provides; it mostly describes output fields, which is not a parameter concern.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific action (list) and a concrete resource (sections and segments in the binary), and it names the output fields (addresses, sizes, permissions). This makes it immediately distinguishable from sibling tools like list_imports, list_strings, and list_exports.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The use case is implied by the resource named in the description, but there is no explicit guidance on when to prefer this over sibling listing tools or when not to use it. An agent can infer it is the tool for section/segment metadata, but no alternatives or exclusions are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_stringsC

Extract printable strings from the binary with their addresses, sections, and lengths.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
offsetNoPagination offset (0-based)
min_lengthNoMinimum string length to include
search_allNoSearch all bytes (izzj) instead of only data sections (izj)
binary_pathYesAbsolute path to the binary file

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It reveals the output shape (addresses, sections, lengths) but does not disclose that this is a read-only operation, whether the binary must be analyzed before strings are indexed, or that search_all=true scans all bytes and is therefore slower and noisier. The 'izzj versus izj' behavioral distinction is left entirely to the schema parameter description.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single 13-word sentence with the action verb front-loaded and zero filler. Every word earns its place by conveying the operation and its output. It could carry slightly more content (usage or behavioral notes) without becoming bloated, but as written it is efficiently structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has 5 parameters, no output schema, and no annotations, so the description must do substantial work. It covers the core output fields, compensating for the missing output schema, but omits usage context, prerequisites, and behavioral caveats. For a tool with two search modes and pagination, this is thin.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all five parameters (limit, offset, min_length, search_all, binary_path) with descriptions and bounds. The tool description adds no parameter-level meaning beyond what the schema provides, so the baseline score of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb ('Extract'), a specific resource ('printable strings from the binary'), and the output fields ('addresses, sections, and lengths'). It is clear and unambiguous as a listing/extraction operation. It does not explicitly differentiate itself from sibling tools like search_string, but the output-schema detail makes the distinction largely inferable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided about when to use this tool versus alternatives such as search_string or search_bytes, nor about prerequisites (e.g., whether the binary must first be loaded or analyzed via analyze_binary). The intended context (binary reverse-engineering) is implied by the tool name and sibling set, but the description itself offers no explicit when-to-use or when-not-to-use direction.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_variablesB

List all local variables, stack variables, and arguments of a function.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoHex address of the function (e.g. "0x08048000")
binary_pathYesAbsolute path to the binary file
function_nameNoName of the function (e.g. "main")

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states a read-only listing operation but does not disclose dependencies such as debug symbols, behavior when no matching function is found, or whether prior analysis is required. The word 'all' is an unqualified promise that may not hold.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no filler. The action and scope are front-loaded, and every word contributes to understanding what the tool does.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is incomplete for practical invocation: binary_path is required, but address and function_name are optional, and the description does not clarify that at least one of these should identify the target function. There is no output schema and no behavioral context, so an agent may call the tool with only binary_path and receive an error.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents address, binary_path, and function_name adequately. The description adds no additional meaning, such as how the optional parameters relate to function selection, but the baseline of 3 is appropriate given the high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb (list) with a specific resource (local variables, stack variables, and arguments) scoped to a function. This clearly distinguishes it from sibling tools such as list_functions and get_function_info.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given for when to use this tool versus alternatives, and there are no exclusions or context notes. The description does not mention that the function must be identified by address or function_name, nor does it reference any sibling tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

r2_commandA

Execute a radare2 command directly and return the raw output. Only commands starting with these prefixes are allowed: a (analysis: aa, aaa, afl, af, ag, ax), p (print: pd, px, pf, pi), i (info: ij, iS, iE, ii, iz), s (seek), f (flags), / (search: /x, /R), e (eval/config), af (analysis functions), ag (analysis graphs), ax (analysis xrefs), CC (comments), dr (debug registers), om (open file map). Blocked characters: ; | > < ` ! ~ { } ( ) $ #!.

ParametersJSON Schema
NameRequiredDescriptionDefault
commandYesThe r2 command to execute (must be on the allowlist)
binary_pathYesAbsolute path to the binary file
analysis_levelNoAnalysis level to run before executing the commandaaa

TDQS

A3.6/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description carries the full burden. It discloses the allowlist, blocked characters, and raw output behavior, which is useful. However, it does not mention that some allowed commands (e, CC, dr, om) may mutate state, nor does it describe error handling on invalid commands. This is a moderate gap for a potentially side-effecting tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense and front-loaded, with no filler. It has some redundancy: the 'a' prefix already includes af, ag, and ax, but these are listed again separately. This is a minor structural wart in an otherwise efficient definition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has no output schema and no annotations, and the description covers purpose, constraints, and output. However, it omits error behavior, state-change warnings, and any guidance for choosing it over specialized siblings. Given the deliberate risk of raw command execution, a more complete description is warranted.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds value by enumerating the exact allowed prefixes and blocked characters, going beyond the schema's generic 'must be on the allowlist' for the command parameter. It also avoids needing to restate binary_path or analysis_level since their schema descriptions and defaults are sufficient.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific verb and resource: execute a radare2 command and return raw output. The allowlist further defines the tool's scope, making it easy to distinguish from specialized sibling tools like disassemble or list_functions.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus the many specialized siblings. The allowlist and blocked characters are invocation constraints, not usage routing. An agent is left to infer that this should only be used when no dedicated tool exists, which is not stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

read_bytesB

Read raw bytes from a specific address in the binary, returned as hex string or formatted hexdump.

ParametersJSON Schema
NameRequiredDescriptionDefault
countNoNumber of bytes to read
formatNoOutput format: "hex" for raw hex string, "hexdump" for formatted hexdumphex
addressYesHex address (e.g. "0x08048000")
binary_pathYesAbsolute path to the binary file

TDQS

B3.3/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description states the core behavior: reading raw bytes and returning them in one of two formats. No annotations are present, so the description carries the full behavioral burden; it is not misleading, but it does not clarify address semantics, end-of-file behavior, or whether the binary must be prepared/analyzed first.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single front-loaded sentence with no wasted words. It conveys the operation, target, and output format efficiently.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read tool with a fully documented schema, the description is mostly adequate. However, it lacks usage boundaries relative to debug memory reads and does not clarify whether 'address' means a virtual address, a file offset, or something else, which is important for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the parameters are already well documented. The description adds little beyond restating the output format choice and that an address is used, which matches the schema's own descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Read'), a clear resource ('binary'), and a specific target ('specific address'), and it names the return formats ('hex string or formatted hexdump'). It is clearly distinct from writing or searching, but it does not explicitly contrast with sibling debug memory reads.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance about when to use read_bytes versus debug_read_memory, disassemble_bytes, or search_bytes. The phrase 'in the binary' implies static file access, but with many related sibling tools, the description leaves the selection largely to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rename_functionA

Rename a function at the given address to a new user-defined name.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressYesHex address of the function (e.g. "0x08048000")
new_nameYesNew name for the function
binary_pathYesAbsolute path to the binary file

TDQS

A3.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description carries the full burden of behavioral disclosure. It states the intended action but does not reveal whether the rename persists to disk, only affects the current analysis session, overwrites existing user names, or how invalid addresses are handled. This leaves important behavioral uncertainty for an agent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence with no filler or redundant wording. It front-loads the verb and resource, then specifies the target name. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple and all three parameters are fully documented in the schema, but there is no output schema and no annotations. The description does not clarify return values, persistence, or failure behavior, leaving some context gaps. It is adequate for a straightforward mutation tool but not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already provides 100% description coverage, including the hex address format, the new name, and the absolute binary path. The description adds no additional parameter-level meaning beyond what the schema defines. The baseline of 3 is appropriate because the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'renames a function at the given address' to a new user-defined name. This clearly distinguishes it from sibling tools, which handle listing, analysis, debugging, or comments rather than renaming. No ambiguity remains about the tool's core purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the tool should be used when a function's name needs to be changed, but it does not explicitly state when to use it versus alternatives. There are no exclusions or mentions of related tools like get_function_info or add_comment. Guidance is therefore adequate but relies on inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rz_calling_conventionsA

List all calling conventions available for the binary architecture using Rizin afcl. Useful for understanding function signatures and ABI details.

ParametersJSON Schema
NameRequiredDescriptionDefault
binary_pathYesAbsolute path to the binary file

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the burden. 'List' implies a read-only operation, and the reference to 'Rizin afcl' gives a concrete mechanism, but it does not disclose output format, prerequisites, or potential side effects. This is adequate but not rich.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no filler. The primary action and scope are front-loaded, and the secondary utility statement is concise and informative.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a low-complexity list operation with one well-documented parameter, the description is largely complete. It could mention whether analysis must be run first or what the returned items look like, but these are minor for this tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for the single binary_path parameter, which is fully described as 'Absolute path to the binary file'. The tool description adds no extra parameter-level detail, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a precise action ('List all calling conventions') and the resource (binary architecture) plus the underlying mechanism (Rizin afcl). This clearly distinguishes it from sibling tools, none of which mention calling conventions.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides context on why this tool is useful ('understanding function signatures and ABI details') but does not explicitly state when not to use it or name alternatives. Since no sibling overlaps with this function, the contextual cue is sufficient for a 4.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rz_entrypointsA

List all entry points of the binary (program entry, TLS callbacks, etc.) using Rizin iej. Returns virtual address, physical address, and entry type.

ParametersJSON Schema

With no annotations, the description carries the behavioral burden. It states the operation is a listing via a read-only Rizin command and specifies the returned fields (virtual address, physical address, entry type). It does not exhaustively describe error behavior or unsupported formats, but 'list' and 'iej' sufficiently convey this is a non-mutating analysis.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no filler; the action and scope are front-loaded and the return values are stated in the second sentence. Every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple one-parameter listing tool this is nearly complete: the schema covers the argument, and the description covers the resource and return fields despite no output schema. It could be slightly more explicit about supported binary formats or failure cases, but nothing essential is missing for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%: the only parameter binary_path is already described as the absolute path to the binary file. The description adds no new parameter detail beyond that, so it meets the baseline but does not exceed it.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and object ('List all entry points of the binary'), gives concrete examples (program entry, TLS callbacks), and names the underlying Rizin command (iej). This clearly differentiates it from sibling listing tools like list_imports, list_exports, and list_sections.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It establishes a clear usage context: whenever the agent needs the binary's entry points and their addresses/types. It does not explicitly name alternatives or when-not-to-use, but no sibling tool provides this specific resource, so the omission is acceptable.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rzil_destroyA

Destroy a persistent RzIL session and release its resources. Use this when you are done with a Rizin emulation session.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idYesRzIL session ID returned by rzil_init

TDQS

A4/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the behavioral disclosure burden. It clearly discloses the destructive nature of the operation and the resource-release side effect. It does not mention whether the session ID becomes invalid or how missing-session errors are handled, but the core behavior is transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences with no filler. The action is front-loaded and the usage guidance is placed immediately after, making the purpose easy to scan and act on.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter cleanup tool with no output schema and no nested structures, the description is largely complete: it says what the tool destroys and when to use it. It does not describe return values or idempotency, but those are not critical for a done-with-session destroy operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single parameter has 100% schema description coverage and is already documented as the 'RzIL session ID returned by rzil_init.' The description adds no additional parameter detail beyond the schema, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Destroy') and a specific resource ('persistent RzIL session'), plus the resource-release side effect. It is clearly distinct from ESIL session tools like esil_destroy, though it does not name a sibling explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit trigger condition: 'Use this when you are done with a Rizin emulation session.' This clearly tells the agent when to call it. It does not spell out when not to use it or name alternatives, so it stops short of a 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rzil_get_memoryA

Read memory contents from the Rizin RzIL emulated memory space at a given address. Requires a persistent session from rzil_init.

ParametersJSON Schema
NameRequiredDescriptionDefault
sizeNoNumber of bytes to read (default 64)
formatNoOutput format: "hex" (raw hex bytes), "string" (ASCII), or "hexdump" (classic hex dump)hex
addressYesAddress (hex) to read memory from
session_idYesRzIL session ID returned by rzil_init

TDQS

A3.9/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the behavioral disclosure burden. It does signal read-only intent and the session-lifecycle requirement, but it does not describe error behavior for invalid sessions or addresses, nor does it disclose any output semantics beyond what the schema already indicates.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences with no filler: the primary action is stated first, and the critical prerequisite is second. Every word adds useful information, and it is appropriately sized for a simple read tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The schema covers all parameter semantics, and the description covers the tool's purpose and main prerequisite. However, with no annotations and no output schema, the agent still has to infer return shape and failure behavior, making the definition adequate but not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all parameters including address format, size bounds, defaults, and format enum. The description adds only the persistent-session context and does not need to explain parameter syntax further.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Read') and identifies the exact resource: 'memory contents from the Rizin RzIL emulated memory space' at a given address. This clearly distinguishes it from ESIL-based memory access and debug-memory reads without needing to inspect the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description states an explicit precondition: 'Requires a persistent session from rzil_init', which tells the agent to initialize RzIL first. It does not explicitly name alternative tools or when-not-to-use conditions, but the RzIL emulated-memory framing gives a clear context for when this tool applies.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rzil_get_registersA

Read all register values or a specific register from the Rizin RzIL VM. Returns typed values including individual CPU flags (zf, cf, sf, etc.) as booleans — superior to ESIL which packs flags into a single register.

ParametersJSON Schema
NameRequiredDescriptionDefault
session_idYesRzIL session ID returned by rzil_init
register_nameNoSpecific register or flag name (e.g. "rax", "rip", "zf", "cf"). If omitted, full VM state is returned.

TDQS

A4.3/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the behavioral disclosure burden. It explicitly states the operation is a read, describes the return shape (typed values, individual flags as booleans), and notes the optionality of register_name. This is sufficient for a non-destructive getter tool, though it does not discuss error behavior or pagination.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no filler. The main function is front-loaded, and the second sentence adds meaningful differentiation from ESIL. Every word contributes to the agent's ability to select and invoke the tool correctly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple two-parameter read-only tool with a complete input schema, the description provides enough context about the operation and return values. It explains the key behavioral distinction (flags as booleans) and the optional register_name behavior, so nothing critical is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema documents both parameters well. The description adds marginal semantic value by mentioning typed values and flag booleans, but the core parameter meaning is already fully covered in the input schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Read') and resource ('all register values or a specific register from the Rizin RzIL VM'). It also differentiates from ESIL by highlighting typed values and individual boolean flags, so an agent can distinguish it from sibling tools like esil_get_registers without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context for when to prefer RzIL over ESIL: it returns typed values and individual flags as booleans, whereas ESIL packs flags into a single register. It does not explicitly state when not to use this tool or name alternative siblings like debug_get_registers, but the RzIL-specific framing provides adequate guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rzil_il_astA

Get the RzIL intermediate language AST for instructions at a given address. Each instruction is lifted to a typed RzIL expression tree with bitvector operations. This is unique to Rizin — r2 ESIL only has flat string expressions.

ParametersJSON Schema
NameRequiredDescriptionDefault
countNoNumber of instructions to lift (default 5)
addressNoAddress to disassemble from (hex). Defaults to entry point.
binary_pathYesAbsolute path to the binary file

TDQS

A4.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the burden of behavioral disclosure. It explains that each instruction is lifted into a typed RzIL expression tree with bitvector operations, which meaningfully describes the tool's output and transformation behavior. It does not explicitly state side-effect-free behavior, but the 'Get' phrasing and AST framing make the read-only intent reasonably clear.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences with no filler. The first sentence front-loads the core action and target, and the second sentence adds valuable technical context about the return type and uniqueness. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is complete for a read-oriented tool with three well-documented parameters and no output schema. It conveys the core return shape (typed RzIL expression tree) and positions the tool relative to ESIL, which helps an agent select and invoke it. A small gap is that it does not describe behavior for edge cases like invalid addresses, but this is not critical given the schema coverage and tool name.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the input schema already documents binary_path, address, and count with descriptions and defaults. The tool description adds no parameter-specific detail beyond mentioning 'instructions at a given address,' which aligns with the address parameter but is already captured in the schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: obtaining the RzIL intermediate language AST for instructions at a given address. It specifies the resource and the operation, and differentiates itself from ESIL by emphasizing typed expression trees versus flat string expressions, which helps distinguish it from sibling tools like esil_expression.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context on when this tool is appropriate: when a structured, typed RzIL AST is needed rather than flat ESIL strings. It explicitly contrasts itself with r2 ESIL, giving an implicit alternative, though it does not name specific sibling tools or state exclusions for other analysis tools like disassemble or decompile_function.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rzil_initA

Initialize the Rizin RzIL virtual machine and return a persistent session_id for subsequent RzIL tool calls. RzIL uses typed bitvectors (BAP Core Theory) for superior emulation fidelity compared to ESIL.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoStart address (hex). If omitted, entry point is used.
binary_pathYesAbsolute path to the binary file

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full responsibility for disclosing behavior. It does disclose the session is persistent and that RzIL uses typed bitvectors, which adds meaningful context. However, it does not mention that sessions may need to be cleaned up via rzil_destroy, nor any side effects or resource considerations of initializing a VM.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences contain all essential information: what the tool initializes, what it returns, and why RzIL is valuable. The key outcome (persistent session_id) is front-loaded, and the ESIL comparison earns its place by differentiating this tool from its closest siblings.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple (2 parameters, no output schema), but because there is no output schema the description should clarify what form the session_id takes. It also leaves the session lifecycle implicit, which matters for a persistent resource. Core usage is sufficiently clear, but the missing cleanup guidance and return format details are notable gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents binary_path and address adequately. The description does not add parameter-specific details such as address format or default behavior, but it does not need to because the schema handles this. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a concrete action ('Initialize the Rizin RzIL virtual machine') and its result ('return a persistent session_id'). It distinguishes this from the ESIL family of sibling tools by explicitly invoking RzIL and comparing it to ESIL. The purpose is immediately clear.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies this tool is the entry point for subsequent RzIL tool calls, and it notes that RzIL has 'superior emulation fidelity compared to ESIL'. However, it does not explicitly state when to choose RzIL over ESIL, nor does it mention any scenario where ESIL would be preferable. Usage context is present but the selection boundary is left implicit.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rzil_list_sessionsA

List all active persistent RzIL emulation sessions with their session IDs, binary paths, and creation times.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A3.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the disclosure burden. It clearly indicates this is a read-only listing operation and discloses the output fields. However, it does not explicitly state that no sessions exist results in an empty list or describe any ordering or session ID format, though these are minor for a list operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, focused sentence with no wasted words. It front-loads the action and resource, then lists the key returned fields, making it easy for an agent to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple, no-parameter listing tool, the description is largely complete: it names what is listed and the fields returned. It could be stronger by noting that it complements the rzil_init/rzil_destroy lifecycle and by distinguishing itself more explicitly from esil_list_sessions, but the core information an agent needs is present.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters and the schema description coverage is 100% with an empty properties object. Since there is nothing to document, the description correctly omits parameter guidance, matching the baseline for a no-parameter tool.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('List') and resource ('active persistent RzIL emulation sessions') and specifies the fields returned (session IDs, binary paths, creation times). It implicitly distinguishes from sibling tools like esil_list_sessions and debug_list_sessions through the 'RzIL' qualifier, though it does not explicitly name those alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description states what the tool does but provides no guidance on when to use it versus alternatives such as esil_list_sessions or debug_list_sessions. There is no mention of prerequisites, such as initializing RzIL first, or exclusions for when this tool should not be used.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rzil_runB

Run RzIL emulation until a target address is reached or maximum steps are exceeded. Uses aezsu for address targets. Requires a persistent session from rzil_init.

ParametersJSON Schema
NameRequiredDescriptionDefault
max_stepsNoMaximum number of steps before stopping (default 1000)
session_idYesRzIL session ID returned by rzil_init
until_addressNoStop emulation when PC equals this address (hex). Uses aezsu internally.

TDQS

B3.4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden. It does disclose termination behavior (stop at address or max steps) and the internal use of aezsu, which is genuinely useful context. But it does not state what happens on timeout (error vs. graceful stop), whether the session state is mutated, or what the call returns.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences front-load the core purpose, with the prerequisite placed last. The 'Uses aezsu for address targets' sentence is somewhat redundant with the schema's until_address description, but it is brief and does not bloat the overall definition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for select-and-invoke: purpose, prerequisite, and termination conditions are present, and the schema fully covers the parameters. However, with no output schema and no annotations, the missing return-value and timeout/error semantics leave a real gap for an agent deciding what to do after the call completes.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents all three parameters with descriptions, defaults, and constraints. The description adds no new parameter semantics — 'uses aezsu' and 'max steps' largely repeat what the schema's until_address and max_steps entries already say — so the high-coverage baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific action ('Run RzIL emulation') with explicit stopping conditions ('until a target address is reached or maximum steps are exceeded'), which behaviorally separates it from the single-step sibling rzil_step. It is clear, though it does not name an alternative sibling the way the strongest definitions do.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a clear prerequisite ('Requires a persistent session from rzil_init'), which guides the correct call sequence. However, it offers no when-not-to-use guidance or explicit routing against alternatives such as rzil_step, esil_run, or trace_execution, so the intended use case is only implied by the run-until semantics.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rzil_set_memoryA

Write data to the Rizin RzIL emulated memory space at a given address. Requires a persistent session from rzil_init.

ParametersJSON Schema
NameRequiredDescriptionDefault
dataYesData to write: hex bytes (e.g. "90909090") or a string if as_string is true
addressYesAddress (hex) to write memory to
as_stringNoIf true, write data as an ASCII string; otherwise write as raw hex bytes
session_idYesRzIL session ID returned by rzil_init

TDQS

A3.9/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must carry the behavioral burden. It discloses the mutation effect and the session precondition, but it does not say what happens on an invalid/expired session, whether the write overwrites existing bytes, or what the tool returns.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, tight sentence with the action front-loaded and the requirement appended. Every word earns its place and there is no filler or repetition beyond the schema.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the core purpose and the key precondition, and the schema covers all parameters. However, with no output schema or annotations, it omits return/error behavior and how this write relates to later rzil_get_memory or rzil_step calls.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description adds little beyond the schema, only restating that data is written to an address and that a session is required; both facts are already in the parameter descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Write data to the Rizin RzIL emulated memory space at a given address.' It clearly differentiates this from sibling tools like rzil_set_register and debug_write_memory by naming the emulated memory domain.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives an explicit prerequisite: 'Requires a persistent session from rzil_init,' which tells an agent this tool cannot be used standalone. It does not explicitly name alternatives or when-not-to-use cases, but the emulated-memory context distinguishes it from debug memory write tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rzil_set_registerA

Set a register value in the Rizin RzIL virtual machine. Requires a persistent session from rzil_init.

ParametersJSON Schema
NameRequiredDescriptionDefault
valueYesValue to set the register to (hex string, e.g. "0x41414141")
session_idYesRzIL session ID returned by rzil_init
register_nameYesRegister name to set (e.g. "rax", "rip", "rsp")

TDQS

A3.8/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the behavioral disclosure burden. It discloses the important session prerequisite, which is genuinely useful beyond the schema. It does not describe what happens on invalid register names, whether the VM state is mutated in place, or what the return/error behavior looks like, but for a simple setter the prerequisite note provides meaningful context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is one compact sentence that front-loads the core action and then adds the critical requirement. There is no fluff, repetition, or unnecessary detail.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a relatively simple setter tool, the description is nearly complete: it defines the action, names the VM context, and states the required session. Because there is no output schema, a note about expected return/error behavior would improve completeness, but the core information needed to invoke the tool correctly is present.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all three parameters with examples. The description adds no additional parameter semantics beyond what the schema provides, so the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('Set a register value') on a specific resource ('Rizin RzIL virtual machine'). This clearly distinguishes it from sibling tools like debug_set_register and esil_set_register by tying it to the RzIL VM, and from rzil_set_memory by targeting registers rather than memory.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives a clear precondition ('Requires a persistent session from rzil_init'), which tells the agent when it is valid to call this tool. However, it does not explicitly explain when to choose rzil_set_register over similar siblings such as esil_set_register or debug_set_register; usage context is implied rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rzil_stepA

Execute one or more instruction steps in the Rizin RzIL emulator and return VM change events and updated register state. Requires a persistent session from rzil_init.

ParametersJSON Schema
NameRequiredDescriptionDefault
countNoNumber of steps to execute (default 1)
session_idYesRzIL session ID returned by rzil_init
show_eventsNoIf true, use aezse to show VM change events (pc_write, var_write). If false, use silent aezs.

TDQS

A3.8/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It accurately notes the return of VM change events and updated register state and the session prerequisite. However, it does not disclose that stepping mutates the persistent session (the VM state advances), nor does it describe error conditions or event semantics in silent mode. The description is accurate but only partially transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that front-loads the action and output, then states the prerequisite. There is no redundant or filler content; every word contributes to understanding.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that there is no output schema and no annotations, the description covers the essential inputs, outputs, and step-count semantics. It does not detail the event structure or the session lifecycle beyond the prerequisite, but for a focused step-execution tool this is reasonably complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so each parameter (count, session_id, show_events) is already documented with defaults and meanings. The description adds minimal new semantics beyond the schema, mainly framing the result as 'VM change events and updated register state.' This is adequate but not additive.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Execute'), a clear resource ('instruction steps in the Rizin RzIL emulator'), and the expected outputs ('VM change events and updated register state'). It also names the required prerequisite ('persistent session from rzil_init'), which helps position it among the RzIL sibling tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives a clear prerequisite by requiring a session from rzil_init, and the phrase 'instruction steps' implies stepwise emulation. However, it does not explicitly contrast with sibling tools like rzil_run or rzil_trace_step, nor does it state when not to use this tool. Usage guidance is implied rather than explicitly stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rzil_trace_stepA

Step the RzIL emulator and return detailed VM change events showing exactly which variables and memory locations were read or written. Uses aezse which outputs typed events like pc_write(old, new) and var_write(name, old, new). Superior to ESIL tracing because events are typed.

ParametersJSON Schema
NameRequiredDescriptionDefault
countNoNumber of steps to trace (default 1)
session_idYesRzIL session ID returned by rzil_init

TDQS

A4.1/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the behavioral burden, and it explains the side-effect (stepping) plus the resulting change events, including concrete examples like pc_write and var_write. It could add more about state mutation or session expectations, but the key behavior is disclosed and not contradicted by any annotation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is tight: the first sentence gives purpose and output, and the second provides the underlying mechanism and comparison. 'Uses aezse' is slightly obscure, but the event examples justify the sentence.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter tool with no output schema, the description compensates by giving event names and an argument format. It doesn't explain how count interacts with event batching or mention lifecycle requirements, but those are largely covered by the schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already defines count and session_id. The description adds no new parameter-level detail beyond the schema, which is the baseline-3 case.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Step'), a specific resource ('the RzIL emulator'), and the unique output ('detailed VM change events... exactly which variables and memory locations were read or written'). The typed-event examples like pc_write(old, new) make its purpose distinct from plain rzil_step and ESIL tracing.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Clearly frames when this tool is useful: detailed typed change events rather than raw emulator tracing, and explicitly positions it as 'Superior to ESIL tracing because events are typed.' It does not explicitly contrast with the sibling rzil_step/rzil_run tools, so no exclusion rule is given, but the intended use case is clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rz_libsA

List all linked libraries (DLLs/shared objects) from the binary using Rizin ilj. Returns a clean JSON array of library names.

ParametersJSON Schema
NameRequiredDescriptionDefault
binary_pathYesAbsolute path to the binary file

TDQS

A3.6/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the behavioral disclosure burden. It clearly indicates a read-only listing operation and states the return shape ('clean JSON array of library names'), which covers basic behavior. However, it does not disclose edge cases such as invalid or missing binary paths, empty library lists, or whether prior analysis is required.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two short sentences with no filler. The first sentence states the action and object, and the second sentence provides the return format, making it appropriately sized and front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple one-parameter tool with no output schema, the description provides the core action, the parameter usage implied by the schema, and the return format. It could be more complete about when to choose rz_libs over sibling tools, but the low complexity limits the impact of that gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The only parameter, binary_path, has 100% schema description coverage ('Absolute path to the binary file'), so the baseline is 3. The description adds little beyond the schema, merely restating that libraries come from the binary.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('List') and resource ('all linked libraries (DLLs/shared objects)'), which is semantically distinct from sibling tools like list_imports, list_exports, and list_sections. It also clarifies the return format, making the tool's intent unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given for when to use rz_libs instead of related listing tools such as list_imports or list_exports. The description does not mention conditions, exclusions, or alternatives, leaving the agent to infer when this tool is appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rz_symbolsB

List all symbols from the binary using Rizin. Returns enriched data including is_imported flag, library origin, flagname, and realname — more detail than r2 isj.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNo
filterNoFilter symbols by name substring (case-insensitive)
offsetNo
binary_pathYesAbsolute path to the binary file
imported_onlyNoIf true, only show imported symbols

TDQS

B3/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the burden and does add useful return-value detail ('is_imported flag, library origin, flagname, realname'). However, 'List all symbols' conflicts with the schema's default limit of 100, and there is no disclosure of pagination, error behavior, or read-only nature.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two crisp sentences with the core action first, then return-value detail. No redundant phrases except possibly 'using Rizin', which adds context without bloating the description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema and no annotations, so the description must cover parameters, pagination, and return shape more fully. It names some output fields but omits filter/imported_only behavior and the limit/offset semantics, leaving the call under-specified for a 5-parameter tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is only 60%; limit and offset lack descriptions. The tool description adds no parameter-level meaning and fails to mention that results are paginated/capped by limit, which is important given the 'all symbols' wording.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a clear action and target ('List all symbols from the binary') and names the enriched output fields. It does not explicitly distinguish this from sibling tools like list_imports or list_exports, though the focus on symbols is fairly specific.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance about when to choose rz_symbols over list_imports, list_exports, or list_functions. The only comparison is to 'r2 isj', which is not among the siblings, so an agent gets no practical routing information.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

rz_typesA

List type definitions from the binary using Rizin separate typed JSON endpoints (tsj/tej/ttj/tuj). Returns structs, enums, typedefs, and unions with full member details. Superior to r2 which returns all types in a single flat list.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNo
filterNoFilter types by name substring (case-insensitive)
offsetNo
categoryNoType category to list (default: all)all
binary_pathYesAbsolute path to the binary file

TDQS

A3.7/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden. It discloses the mechanism (tsj/tej/ttj/tuj endpoints) and hints the output is structured per category, but does not state whether the operation is side-effect-free, whether prior analysis is a prerequisite, or how it behaves on an unanalyzed binary. 'List' only implicitly conveys read-only behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tightly-written sentences with no filler: action plus mechanism, output contents, and comparison to the alternative. The most important information is front-loaded in the first sentence, and every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 5-parameter tool with no annotations and no output schema, the description covers the main purpose and return contents but omits prerequisites and error behavior, notably that a sibling analyze_types exists and analysis may need to run first. The mention of 'full member details' partially compensates for the missing output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 60% (limit and offset lack descriptions), shifting some burden to the description. The description adds meaning by mapping the category enum values to concrete output ('Returns structs, enums, typedefs, and unions'), reinforcing what category=structs produces. It does not clarify pagination semantics or the binary_path requirement beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('List type definitions from the binary') and enumerates exactly what is returned: structs, enums, typedefs, and unions with full member details. The closing comparison to r2's single flat list helps distinguish it from the generic r2_command sibling without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The third sentence implies this tool should be preferred over raw r2 for type listing because it returns structured, separate typed JSON rather than a flat list. However, the alternative is referenced only as 'r2' rather than the actual sibling r2_command, and there is no explicit when-to-use condition, such as requiring prior analysis or when category filtering is appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

search_bytesA

Search for a hex byte pattern across the binary and return all matching addresses.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
offsetNoPagination offset (0-based)
patternYesHex byte pattern to search for, dots (..) as wildcards
binary_pathYesAbsolute path to the binary file

TDQS

A3.8/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the transparency burden and does state the core search-and-return behavior. However, saying 'return all matching addresses' overstates the default limit of 100 and the pagination-oriented offset/limit parameters. It also does not mention output format or what happens when no matches are found.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single well-structured sentence with no filler. It front-loads the key operation, target, and output, making it immediately scannable for an agent.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a straightforward search tool, the description plus the fully documented schema is enough for basic correct invocation. It is missing guidance on output formatting, pagination behavior, and the default limit, but the schema covers the parameters and the core return value is stated.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema provides 100% coverage of all four parameters with descriptions, so the baseline is 3. The tool description adds little beyond restating that the pattern is hex and the target is a binary file; wildcard behavior and pagination semantics are already in the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names the operation (search), the resource (binary), the criterion (hex byte pattern), and the result (matching addresses). This clearly differentiates it from siblings like search_string, read_bytes, and search_rop_gadgets without needing to inspect schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The intended use is implied by the hex-byte-pattern wording, but the description does not explicitly state when to use this tool instead of alternatives such as search_string or search_rop_gadgets. No exclusions or routing guidance are provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

search_rop_gadgetsA

Search for ROP gadgets in the binary matching optional instruction constraints.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
queryNoInstruction filter (e.g. "pop rdi") to match specific gadgets
offsetNoPagination offset (0-based)
max_lengthNoMaximum number of instructions per gadget
binary_pathYesAbsolute path to the binary file

TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the transparency burden. 'Search' signals a read-only intent, and 'optional instruction constraints' hints at filtering behavior, but it does not disclose return format, default query behavior, ordering, or pagination semantics. This is a moderate gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence with no filler; the core action, resource, and qualifier are front-loaded and every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a straightforward search tool with fully described parameters and clear scope, the description is largely complete. It would be more complete with an explicit note about the returned gadget format, but the absence of an output schema is partially mitigated by the self-describing nature of a search result list.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all five parameters, including defaults and bounds. The description's mention of 'optional instruction constraints' adds slight semantic context for query/max_length but does no more than echo the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a precise verb ('Search'), a specific resource ('ROP gadgets'), and the scope ('in the binary'), plus the filtering dimension ('optional instruction constraints'). This clearly distinguishes it from sibling search tools like search_bytes or search_string.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It provides clear context for when the tool applies: when the goal is ROP gadget discovery with optional instruction filtering. It does not explicitly name alternatives or state when not to use it, so it stops short of a 5, but the usage context is unambiguous.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

search_stringC

Search for a string pattern in the binary and return all matching locations.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMax results to return
queryYesString pattern to search for
offsetNoPagination offset (0-based)
binary_pathYesAbsolute path to the binary file
case_sensitiveNoWhether the search is case-sensitive

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description carries the full burden of behavioral disclosure. It implies a read-only search action but does not clarify matching semantics (literal vs. regex, encoding, offset addressing), and it claims to return 'all' matching locations while the schema enforces limit/offset pagination.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence with no filler, and the core verb and object are front-loaded. It is short and scannable, though it sacrifices useful behavioral detail for brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With five parameters, no annotations, no output schema, and several sibling search tools, this minimal description is insufficient. It does not explain the return format, pagination behavior, case-sensitivity defaults, or how this search differs from search_bytes, leaving important operational details implicit.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the input schema already documents all parameters including defaults, bounds, and meanings. The description adds little beyond the schema, and 'string pattern' is slightly ambiguous, but the baseline of 3 is appropriate given the high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear action ('Search for a string pattern'), the resource ('in the binary'), and the result ('return all matching locations'). It is distinct enough from the sibling search_bytes because it targets string patterns, though it does not explicitly differentiate itself.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use search_string versus closely related tools like search_bytes, search_rop_gadgets, or list_strings. The description provides no exclusions, prerequisites, or context that would help an agent choose this tool over alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

shellcode_analyzeA

Analyze raw shellcode bytes by loading them as a memory blob, disassembling, and identifying syscalls and patterns.

ParametersJSON Schema
NameRequiredDescriptionDefault
hex_bytesYesHex-encoded shellcode bytes
architectureNoTarget architecture for disassemblyx86
base_addressNoBase address for the shellcode mapping0x10000

TDQS

A3.9/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses the main behavior—loading bytes into a memory blob, disassembling, and scanning for syscalls/patterns—which implies static analysis. However, with no annotations available, it does not explicitly state that the shellcode is never executed or whether any in-memory modification occurs, leaving some safety-related ambiguity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, dense sentence that front-loads the primary purpose and then briefly states the method. There is no redundant or filler language.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers what the tool does and the general approach, but there is no output schema and the description does not mention what kind of results are returned, e.g., disassembly listing, syscall list, or pattern matches. For a tool with no output schema, a bit more detail about the return value or expected result format would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already provides 100% parameter coverage with descriptions for hex_bytes, architecture, and base_address. The tool description does not add further parameter-level detail, so it neither improves nor harms parameter understanding; it meets the baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific resource (raw shellcode bytes) and a concrete analysis pipeline: load as memory blob, disassemble, identify syscalls and patterns. This clearly separates it from file-oriented siblings like analyze_binary and from plain disassemblers like disassemble_bytes because it emphasizes shellcode-specific analysis.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'Analyze raw shellcode bytes' gives a clear context for when to use the tool: when the input is raw shellcode rather than a full binary. It does not explicitly name alternatives or state when not to use it, so it stops short of full exclusion guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

solve_crackmeA

Automatically attempt to solve a crackme by extracting constraints, identifying success/fail paths, and brute-forcing input character by character using ESIL emulation.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoHex address of the check function
charsetNoCharacter set to brute-forceprintable
binary_pathYesAbsolute path to the binary file
input_lengthNoMaximum input length to try
function_nameNoCheck/validation function name
input_addressNoMemory address where input is stored (auto-detected if omitted)
max_steps_per_charNoMax ESIL steps per character attempt

TDQS

A3.9/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the behavioral disclosure burden. It does disclose the core behavior: extracting constraints, identifying paths, and brute-forcing through ESIL emulation. However, it does not mention side effects, what happens on success or failure, runtime costs, or whether the binary is executed natively or only emulated, leaving meaningful gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single compact sentence that front-loads the primary purpose and then describes the method without filler. Every clause contributes useful information, and it does not repeat schema details or annotation data.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a complex 7-parameter tool with no output schema and no annotations, the description covers the high-level strategy but omits important operational details such as what the tool returns, failure modes, timeouts, and whether it modifies the binary. The comprehensive parameter schema compensates somewhat, but the missing return/behavior contract makes it only partially complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so all seven parameters are already documented with descriptions, enums, defaults, and constraints. The tool description adds no parameter-specific meaning, so the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('solve a crackme') with a clear resource and method: extracting constraints, identifying success/fail paths, and brute-forcing character by character via ESIL emulation. This clearly distinguishes it from sibling tools like find_constraints, esil_run, or analyze_binary, which are lower-level or partial operations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrasing 'Automatically attempt to solve a crackme' gives clear context for when this tool is appropriate: when the goal is full automated solving rather than manual reverse engineering. It does not explicitly name alternatives or exclusion cases, but the high-level 'automatically solve' intent is clear relative to the more granular sibling tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

trace_executionB

Trace execution using ESIL emulation, logging comparisons, branches, memory access, and register changes at each step.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressNoStart address for emulation (hex). If omitted, entry point is used.
max_stepsNoMaximum number of steps to emulate
stack_sizeNoESIL stack size in bytes
binary_pathYesAbsolute path to the binary file
log_registersNoLog full register state at each interesting event (verbose)
stack_addressNoESIL stack base address0x00100000
until_addressNoStop emulation when this address is reached (hex)

TDQS

B3.1/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden for behavioral disclosure. It usefully states that the tool logs comparisons, branches, memory access, and register changes, which goes beyond the schema. However, it does not disclose side effects, whether state is mutated, output format, or stopping behavior beyond the parameters themselves.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that front-loads the core action and then lists the logged event types. It is concise and efficient with no filler, though it could be slightly more structured if it separated the trace action from the logging behavior.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 7 parameters, no annotations, no output schema, and many closely related ESIL/rzil/debug siblings, the description is too thin. It does not explain what kind of result the agent should expect, how it relates to ESIL sessions, or when to prefer this over lower-level step/run tools, leaving significant gaps for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% parameter coverage, so the schema already documents every parameter. The description adds a useful hint about logging register state at events, but it does not materially deepen understanding of the parameters beyond what the schema provides, so the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies a specific verb ('Trace execution'), the mechanism (ESIL emulation), and the observable outputs (comparisons, branches, memory access, register changes). It does not explicitly differentiate from sibling tools like esil_step, esil_run, or rzil_trace_step, but the high-level tracing intent is reasonably clear.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given about when to use this tool versus the many esil_*, rzil_*, and debug_* siblings. The description implies usage for execution tracing but does not state prerequisites, exclusions, or alternatives, leaving an agent to infer selection criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.8/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full transparency burden. It does disclose the one-shot, multi-category analysis behavior, which is useful. But it remains silent on potential side effects (e.g., mutating analysis state), performance/cost implications of 'comprehensive' triage, or whether the analysis is read-only.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, well-structured sentence that leads with the action and scope, then lists the concrete output categories. Every clause earns its place and there is no filler or repetition of the tool name.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The required binary_path, the optional max_strings/max_functions limits, and the analysis_level enum are all documented elsewhere, and the description enumerates the expected output categories. However, since there is no output schema, the exact return structure/format is not described, and the description does not clarify how the returned data is organized across the many listed categories.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all four parameters are already explained in the input schema, giving a baseline of 3. The description adds no parameter-specific detail beyond what the schema provides, which is acceptable but not additive.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Perform') and clear resource scope ('binary triage'), then enumerates eight concrete output areas: file info, sections, imports, exports, strings, functions, entry points, and security features. The 'one-shot' / 'single call' phrasing differentiates it from sibling single-purpose tools like list_sections, list_imports, and list_strings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'in a single call' implies this tool is for consolidated overviews rather than repeated individual list_* calls, so usage context is indirectly present. However, it never explicitly states when to prefer triage_binary over the overlapping sibling analyze_binary, nor does it mention when deeper per-function analysis would be more appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

write_bytesC

Patch bytes at a specific address in the binary using hex bytes or assembly instructions.

ParametersJSON Schema
NameRequiredDescriptionDefault
addressYesHex address to write at (e.g. "0x08048000")
assemblyNoAssembly instruction to assemble and write (e.g. "nop" or "jmp 0x08048100")
hex_bytesNoHex bytes to write (e.g. "9090" for two NOPs)
binary_pathYesAbsolute path to the binary file

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

There are no annotations, so the description carries full responsibility for disclosing behavior. It reveals that the operation patches/persists bytes in a binary, but does not mention potential irreversibility, file corruption risk, or permissions needed. For a mutating, file-modifying tool this is a significant transparency gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that front-loads the core action, target, and accepted input modes. Every phrase earns its place, and there is no redundant or filler content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that this is a destructive write operation with no annotations and no output schema, the description is too thin. It omits the either/or relationship between assembly and hex_bytes, does not state whether the patch is written to disk, and gives no hint about return values or failure conditions, leaving important operational ambiguity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so each parameter is already documented. The description adds a small amount of relational meaning by stating that hex bytes or assembly instructions can be used, but it does not clarify whether both can be specified together or whether at least one is required. This keeps it at the baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific verb ('Patch') and resource ('bytes at a specific address in the binary'), and indicates the two input modes. It is distinct enough from generic read/debug tools, though it does not explicitly name or contrast any sibling tool such as debug_write_memory.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given about when to use this tool versus alternatives like debug_write_memory or read_bytes. There is no mention of prerequisites, exclusions, or conditions that should trigger this tool over another, so the agent is left to infer usage from the name and short description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

B3.1/5.0

Scored across 85 tools

Disambiguation2/5

Many tools overlap in scope: analyze_types and rz_types both list type definitions, rz_symbols overlaps list_imports/list_exports, and the ESIL/RzIL families expose nearly identical operations. Descriptions help differentiate contexts, but the parallel emulation backends and broad composite tools like triage_binary and exploit_hunter create real selection ambiguity.

Naming Consistency3/5

Most tools use snake_case and the debug_*, esil_*, and rzil_* families are internally consistent. However, the overall set mixes verb_noun patterns like analyze_binary and list_functions with noun_verb names like shellcode_analyze and file_format_analyzer, plus noun-only names like binary_headers, exploit_hunter, and r2_command.

Tool Count1/5

85 tools is far beyond the 16-25 'heavy' range and well over the 50+ threshold for an extreme mismatch. The count is inflated by parallel ESIL/RzIL tool families, redundant symbol/type listings, and multiple one-shot composite analyzers that could be consolidated.

Completeness4/5

The server covers an exceptionally broad reverse-engineering workflow: loading/analysis, disassembly, decompilation, patching, searching, debugging, emulation, diffing, and vulnerability scanning. Minor gaps exist around lifecycle management, such as no explicit close/release of the analyzed binary, no save/export of patched output, and no comment removal, but agents can usually work around these.
