What It Does · Tools · Architecture · Stack · Quickstart · Changelog · Contributing
HALO is an autonomous security agent that runs inside a Linux environment driven by a local LLM — Gemma 4-12B (uncensored / abliterated) served through LM Studio. It plans, runs reconnaissance, chains attacks based on what it finds, and writes a professional pentest report on its own. Everything runs locally: no cloud, no API keys, nothing leaves your machine.
One word starts an engagement: engage.
🔍 Autonomous recon — masscan + nmap to discover open ports and services
⚔️ Autonomous attack loop — selects and chains tools based on what it finds
🌐 Web recon → attack pipeline — apex-to-URL enumeration (subdomains, hosts, historical URLs), content discovery, template scanning and XSS, with automatic flag capture on CTF-style web targets
✅ Verified breaches, not banners — every attempt carries a single-use
challenge/nonce the exploit must echo from inside the popped shell; a bare
uid=0 banner or a tarpit can't forge it, so a confirmed breach is a real one
(execution-derived evidence, consume-once at the gate)
🎯 Curated PoC library — deterministic, self-evident exploits (vsftpd 2.3.4, ingreslock, UnrealIRCd) fired through a sandboxed delivery primitive that returns a real shell, not a guess
🧠 Persistent negative-experience cache — learns what fails across all sessions and stops wasting cycles on proven dead ends
🧩 Adaptive skill injection — loads relevant attack playbooks into the prompt based on the current goal
📝 Automatic HTML reports — compiles findings into a branded report on exit
🔒 100% local — Gemma 4-12B in LM Studio; nothing leaves your machine

42 tools sit behind the agent's decision loop, all routed through the same
failure-caching layer. They are defined once in the TOOLS schema registry in
halo_tools.py and served over both transports (MCP and HTTP).

A single tool engine (halo_tools.py) owns the arsenal and its schemas; two
thin transports sit on top of it, so the tools are defined exactly once:
agent_loop.py ──HTTP─► tool_server.py ─┐
├─► halo_tools.py ──► security tools
MCP clients ──stdio► mcp_server.py ──┘ (42-tool engine +
schema registry)
│
├─► agent_cache.py (persistent negative-experience cache)
├─► skills.py (adaptive playbook injection)
└─► report_generator.py (auto HTML pentest report on exit)mcp_server.py — a spec-compliant Model Context Protocol server
(stdio, JSON-RPC 2.0). Point any MCP client (Claude Desktop, IDE agents,
inspectors) or an MCP registry at it to use HALO's arsenal as standard tools.
tool_server.py — the local Flask HTTP tool server (port 8000) the
autonomous agent loop drives.
// e.g. an MCP client config
{
"mcpServers": {
"halo": { "command": "python3", "args": ["/abs/path/to/mcp_server.py"] }
}
}A ready-to-submit registry manifest lives in server.json.
Engagements are coordinated by a set of specialist agents that pass a shared
message schema (agent_schema.py):
Agent | Role |
| Turns a goal into an ordered plan |
| Routes tasks to the right specialist |
| Surfaces candidate vulnerabilities |
| Branches into vuln-class specialists (SQLi, brute force, IDOR, SSRF, XSS, auth) |
| Confirms findings against real evidence before they count |
| Diagnoses failed tool runs and adjusts |
The negative-experience cache fingerprints every tool call. A call that fails gets one retry; fail twice and it is blacklisted, so the agent moves on to a more practical tool for the job. Over an engagement the agent structures its own trial-and-error learning — building context, avoiding repeated dead ends, and escalating intelligently — rather than re-running what it has already proven doesn't work.
The hard problem with an autonomous attacker is knowing whether it actually broke in or just parroted a hopeful banner. HALO answers this with a challenge-response gate:
The orchestrator mints a per-attempt nonce, bound to that target and the exact payload hash, before firing.
A breach only counts if the tool output carries a structured
HALO-EVIDENCE nonce=… level=… line echoing that nonce — which the
delivery primitive (pocs/_delivery.py) can only produce by running code
inside the shell it claims to have.
The nonce is consume-once: the gate (exploitation_core.py:breach_confirmed)
rejects a replayed or never-minted nonce, so a tarpit, a reflected string, or a
static uid=0 banner cannot forge a confirmation.
The curated PoCs in pocs/ are deterministic, self-evident bugs
(vsftpd 2.3.4, ingreslock 1524, UnrealIRCd 3.2.8.1) that pass this gate honestly —
they land a real root shell or they report nothing.
HALO was built solo, from the ground up, in under six months by a self-taught developer and security researcher. The multi-agent core came together one specialist at a time, each verified against a real target before moving on:
Shared language: a common message schema (agent_schema.py) so the agents can talk to each other
Planner: turns a goal into an ordered plan, verified against live LM Studio
Orchestrator: routes each task to the right specialist
Vuln Discovery: surfaces candidate vulnerabilities, tested against a live Metasploitable target
Attacker: branches into SQLi / brute-force / IDOR / SSRF / XSS / auth specialists
Debugger: diagnoses failed tool runs and adjusts
Validator + reporting: findings are confirmed against real evidence before they count, then compiled into a client-readable report
From there the arsenal grew to 42 tools, a full web recon → attack pipeline with flag capture, and challenge-response breach confirmation, while the negative-experience cache turned trial-and-error into persistent learning across sessions. Active development continues — new capabilities are pushed regularly; see the changelog for the shipped milestones.

Read and return the contents of a file.
| Name | Required | Description | Default |
|---|---|---|---|
| filename | Yes | Path to read. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden but offers minimal behavioral disclosure. It omits critical traits such as how it handles missing files, binary files, large files, or encoding. The agent cannot anticipate error behavior or limitations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with a single sentence that immediately conveys the action. Every word earns its place; there is no fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema), the description is largely complete. However, it could briefly mention that the tool returns file contents as text, but that is implied by 'contents.' It adequately covers the core functionality.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a single parameter 'filename' described as 'Path to read.' The description does not add extra meaning beyond the schema. Baseline 3 is appropriate as the schema already defines the parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Read and return the contents of a file' uses a specific verb ('Read') and resource ('file'), clearly stating the tool's function. It distinguishes itself from siblings like write_file (write) and run_command (execute commands), 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.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like run_command with cat or run_cat. The description does not mention contexts, prerequisites, or exclusions, leaving the agent without decision support.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Enumerate the attack surface of an AWS environment.
| Name | Required | Description | Default |
|---|---|---|---|
| profile | No | AWS profile name. | default |
| command_type | No | cloudfox subcommand. | all-checks |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully convey behavioral traits. It fails to mention whether the tool modifies the environment, requires AWS credentials, or has side effects. The single sentence offers no insight into the tool's impact or requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence with no superfluous words. It is as concise as possible while conveying the core purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity of the tool (2 optional parameters, no output schema), the description is incomplete. It lacks context about the tool's typical output, whether it is safe to run in read-only mode, and what 'enumerate the attack surface' entails in practice.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Both parameters have descriptions in the input schema (profile and command_type), giving 100% coverage. The tool description adds no additional meaning beyond what the schema already provides, such as acceptable values for command_type or how the profile parameter is used.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Enumerate the attack surface of an AWS environment' clearly states the tool's purpose: to run CloudFox for AWS enumeration. It distinguishes run_cloudfox from sibling tools that target different domains (e.g., network scanning with run_nmap, web enumeration with run_ffuf).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
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 like run_nuclei or run_searchsploit. There is no mention of prerequisites, common use cases, or scenarios where this tool is inappropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Execute an arbitrary shell command with sudo auto-escalation on permission errors.
| Name | Required | Description | Default |
|---|---|---|---|
| command | Yes | Full shell command line to execute. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must disclose all behavior. It mentions sudo auto-escalation but omits critical traits: destructive potential, security implications, timeout behavior, output format, environmental constraints. For an arbitrary command execution tool, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence with no filler. Front-loaded with verb and resource. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema or annotations. Given the complexity of arbitrary command execution, the description should cover return values, error handling, and safety warnings. It is under-specified for safe agent usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema covers 100% with clear parameter description. The tool description adds only the auto-escalation context, which is behavioral not semantic. Baseline 3 is appropriate since schema already handles parameter meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description uses specific verb 'Execute' and resource 'arbitrary shell command', clearly distinguishing it from sibling run_* tools that are specific to particular executables. The auto-escalation detail further clarifies capability.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this generic tool versus the many specific run_* siblings (e.g., use run_nmap for nmap scans). Lacks when-not-to-use or alternative recommendations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Issue an HTTP request and return the verbose response.
| Name | Required | Description | Default |
|---|---|---|---|
| url | Yes | Request URL. | |
| data | No | Request body for POST/PUT/PATCH. | |
| method | No | HTTP method. | GET |
| headers | No | Single header string. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full behavioral disclosure burden, but it only states it returns the verbose response. It does not mention timeout, error handling, redirects, authentication, or other important HTTP behaviors.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that efficiently communicates the tool's purpose without any wasted words or structure.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 4 parameters and no output schema, the description is minimal but sufficient for a simple HTTP request tool. It covers the core functionality but lacks detail on edge cases or response format.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description adds no additional meaning beyond the schema, but the schema already adequately defines each parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it issues an HTTP request and returns the verbose response, which is a specific verb and resource. It distinguishes from sibling tools like run_ffuf (fuzzing) or run_nmap (network scanning) by being a general HTTP client, but does not explicitly differentiate from run_wget.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
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. It does not mention prerequisites, typical use cases, or exclusions, leaving the agent to infer 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.
Enumerate SMB/Samba shares, users, and policies on a host.
| Name | Required | Description | Default |
|---|---|---|---|
| target | Yes | Target host. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations given; description does not disclose authentication needs, potential destructiveness, or rate limits. Simply states 'enumerate' without behavioral details.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, no unnecessary words, but lacks depth; still concise and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequate for a simple one-parameter tool, but lacks behavioral context and output description; not fully complete given no annotations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Only one parameter with full schema coverage; description adds no additional meaning beyond the schema's 'Target host.'
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool enumerates SMB/Samba shares, users, and policies, which is specific and distinguishes it from other run_* tools like run_nmap or run_sqlmap.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives, no prerequisites or context provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
LAST RESORT: run a custom Python PoC in the isolated sandbox runner. Requires operator approval upstream.
| Name | Required | Description | Default |
|---|---|---|---|
| code | Yes | Full Python script source. | |
| phase | No | 'test' (no network) or 'attack'. | test |
| target | No | Target ip or ip:port. | |
| timeout | No | Seconds before kill. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. Mentions isolated sandbox and operator approval, but lacks details on error handling, return value, or logging. Does not disclose what happens on failure or success.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise: two short sentences, front-loaded with 'LAST RESORT'. No redundant information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers main purpose and safety, but fails to explain what happens after execution (e.g., output, results). No output schema, so description should mention return behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 100% coverage with descriptions for all parameters. Tool description adds context (custom PoC, sandbox) but does not enhance parameter semantics beyond what schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the tool runs a custom Python PoC in an isolated sandbox, distinguishing it from sibling tools like run_nmap or run_sqlmap which are specific tools. The 'LAST RESORT' emphasizes its use case.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly marks as 'LAST RESORT', implying other tools should be tried first, and requires operator approval. Does not name specific alternatives but context from sibling tools provides that.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Fast web fuzzer for directories, parameters, and vhosts.
| Name | Required | Description | Default |
|---|---|---|---|
| url | Yes | URL containing or receiving the FUZZ marker. | |
| param | No | Fuzz marker. | FUZZ |
| wordlist | No | Wordlist path. | /usr/share/seclists/Discovery/Web-Content/common.txt |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations and the description only says 'Fast web fuzzer', which does not disclose behavioral traits such as destructive potential, authentication needs, rate limits, or output format. Basic transparency is lacking.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise (6 words) but lacks sufficient detail for an agent to use the tool effectively. It is efficient but at the cost of completeness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, no annotations, and a minimal description, the context is incomplete. An agent would need more information about expected output, prerequisites, and tool behavior to use it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for all 3 parameters. The tool description does not add extra meaning beyond the schema, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies it as a 'web fuzzer' for directories, parameters, and vhosts, which is a specific verb+resource. However, it does not differentiate from sibling tools like run_gobuster, which has overlapping capabilities.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives (e.g., run_gobuster, run_nuclei). The description merely states what it is, 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.
Brute-force web content, DNS, or vhosts against a wordlist.
| Name | Required | Description | Default |
|---|---|---|---|
| mode | No | gobuster mode: dir/dns/vhost. | dir |
| target | Yes | Base URL or host. | |
| wordlist | No | Wordlist path. | /usr/share/seclists/Discovery/Web-Content/common.txt |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It states 'brute-force' implying potentially aggressive behavior, but does not mention rate limiting, authentication needs, resource impact, or whether the tool is read-only. This is insufficient for an agent to anticipate 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence. It is front-loaded with the core action, though could be more structured with explicit mode mention.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (multiple modes, no output schema, no annotations), the description is insufficient. It fails to explain return values, progress indication, or how it differs from similar tools in the sibling list.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so parameters are already documented. The description adds minimal extra meaning beyond listing modes. It does not clarify path formats or expected input conventions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool brute-forces web content, DNS, or vhosts using a wordlist. It identifies the verb and resources, but does not explicitly distinguish from closely related sibling tools like run_ffuf.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives such as run_ffuf, run_nikto, or run_nmap. There is no mention of prerequisites, exclusions, or context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Probe hosts for live HTTP services (status, title, tech detection).
| Name | Required | Description | Default |
|---|---|---|---|
| flags | No | Override httpx flags. | |
| target | Yes | URL or host. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only states it probes for live HTTP services. It does not disclose behavioral details like redirect handling, timeout, rate limits, or response format, leaving agent uncertain about execution.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Description is a single, front-loaded sentence with no redundant information. Every word serves a purpose, making it efficient for quick comprehension.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Schema coverage is 100% and the description adds no additional meaning. It does not clarify the format or purpose of 'target' (e.g., IP, domain) or the meaning of 'attack_type' options beyond the schema defaults.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description names the Social-Engineer Toolkit but uses the vague verb 'Drive' and does not specify what action is performed (e.g., launch, configure). It partially distinguishes from siblings like run_nmap by mentioning 'scripted attack scenario' but lacks precision.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives such as run_exploit or run_sqlmap. No mention of prerequisites, scenarios, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Hunt a username across social networks and public sites.
| Name | Required | Description | Default |
|---|---|---|---|
| username | Yes | Username to search for. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must convey behavioral traits. It only states the action without disclosing how the search is performed (e.g., asynchronous, rate limits, network requirements), what the output looks like, or whether the tool is read-only or destructive. This lack of transparency hinders an agent's ability to anticipate behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single 9-word sentence that immediately communicates the core action. It is efficiently structured with the verb first. While concise, it sacrifices completeness for brevity, which is acceptable for a simple tool but borderline under-specified.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has no output schema and no annotations, the description should provide more context about what happens after invocation, such as whether results are returned, how to interpret them, or any network dependencies. The current description is insufficient for an agent to fully understand the tool's complete behavior and output.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema covers 100% of parameters with a clear description for 'username'. The tool description adds context that the username is searched across social networks and public sites, reinforcing the parameter's purpose. However, it does not add extra constraints or format details beyond what the schema provides, 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.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb 'hunt' and clearly identifies the resource 'username across social networks and public sites'. It effectively distinguishes itself from sibling tools like run_nmap or run_gobuster, which are focused on different tasks such as port scanning or directory enumeration.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description lacks any guidance on when to use this tool versus alternatives. It does not mention prerequisites, contexts where it is appropriate, or situations where another tool would be preferable. The agent is left to infer usage 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.
Look up an internet-exposed host in Shodan (open ports, services, banners).
| Name | Required | Description | Default |
|---|---|---|---|
| query | Yes | IP address or hostname. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden for behavioral transparency. It only states the lookup action but does not disclose whether it is read-only, requires authentication, has rate limits, or any side effects. The minimal description leaves the agent uninformed about important operational constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, perfectly front-loaded with the essential purpose. No redundant words; every part contributes to understanding. Given the tool's simplicity, this is optimal conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple lookup tool with one parameter and no output schema, the description covers the basic functionality. However, it lacks details about return format, pagination, error handling, and any dependencies (e.g., network access). The absence of usage context relative to 28 sibling tools also reduces completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% (one parameter 'query' with description 'IP address or hostname'). The description adds a slight nuance by specifying 'internet-exposed host', which clarifies the scope of the query. However, it does not elaborate on input format, validation, or examples. At high coverage, the baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('look up an internet-exposed host'), the target resource (Shodan), and the information returned (open ports, services, banners). It distinctly separates this tool from siblings like run_nmap (network scanning) or run_httpx (HTTP probing) by specifying Shodan as the data source.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No usage guidance is provided. The description does not indicate when to prefer this tool over alternatives (e.g., run_shodan vs run_nmap for external recon), nor does it mention prerequisites (e.g., API key) or limitations (e.g., only works for publicly exposed hosts). The agent must infer context from the sibling list.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Automated SQL injection detection and exploitation against a URL.
| Name | Required | Description | Default |
|---|---|---|---|
| dbms | No | Force a DBMS backend. | |
| risk | No | Risk level 1-3. | 1 |
| level | No | Test level 1-5. | 1 |
| target | Yes | Target URL with parameters. | |
| technique | No | Injection technique letters. | B |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must convey behavioral traits. It mentions 'detection and exploitation' implying aggressive actions, but lacks details on safety, permissions, or 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence is concise and front-loaded with key action. However, slightly under-specified for a complex tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a complex penetration testing tool like sqlmap, the description is too sparse. It omits risk of exploitation, return values, and operational context. Incomplete given no output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% parameter description coverage, so description adds no additional parameter meaning beyond the schema. Baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it detects and exploits SQL injection against a URL, which is specific and distinguishes from sibling tools like run_nmap or run_ffuf. However, it could elaborate more on the automation aspect.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use or avoid this tool. It simply describes functionality without context of alternatives or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Passively enumerate subdomains of a domain.
| Name | Required | Description | Default |
|---|---|---|---|
| domain | Yes | Apex domain. | |
| silent | No | Silent output. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The term 'passively' indicates a non-intrusive behavior, which is helpful. However, no annotations are provided, and the description lacks details on output format, dependencies, or potential limitations (e.g., API keys, network access).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, no fluff, front-loaded with the key action. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with two parameters, the description is minimal. It omits important context like expected output, passive sources used, and whether internet access is required. Given the large number of sibling tools, more context would aid correct selection.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already provides descriptions for both parameters ('domain' and 'silent'), achieving 100% coverage. The tool description does not add extra semantic value beyond what the schema offers.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'enumerate', the resource 'subdomains', and the scope 'of a domain', which is specific and distinguishes it from sibling tools like run_nmap or run_gobuster that perform active scanning.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives, such as run_ffuf or run_gobuster. The description does not mention prerequisites, limitations, or context for use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Fingerprint the web application firewall / security solution in front of a target.
| Name | Required | Description | Default |
|---|---|---|---|
| target | Yes | URL or host to fingerprint. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It does not mention that the tool sends HTTP requests, may be blocked, or any consequences. This is insufficient for an agent to understand the tool's 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that conveys the essential purpose without any unnecessary words. It is perfectly concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one parameter and no output schema or annotations, the description is minimally adequate. However, it lacks details about output format, prerequisites, or limitations, leaving gaps for the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one parameter with a description ('URL or host to fingerprint.'). The tool description adds no additional meaning beyond the schema, and schema coverage is 100%. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Fingerprint' and the resource 'web application firewall / security solution in front of a target', making the tool's purpose immediately understandable. It distinguishes from sibling tools like run_nmap or run_curl by specifying WAF fingerprinting.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for identifying WAFs but provides no explicit when-to-use, when-not-to-use, or alternatives among sibling tools. The context of siblings (e.g., run_nmap, run_curl) suggests this is for after initial reconnaissance, but no guidance is given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Download a file or mirror content from a URL.
| Name | Required | Description | Default |
|---|---|---|---|
| url | Yes | URL to fetch. | |
| output | No | Output filename. | |
| recursive | No | Recursive download. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden for behavioral disclosure. It only states the basic action, omitting details like redirect handling, timeouts, authentication, or error behavior. This is insufficient for an agent to anticipate side effects or prerequisites.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence that efficiently conveys the core purpose. It could be expanded to include additional behavioral context without losing conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the low complexity (3 params, no output schema, no nested objects), the description is adequate for basic use. However, it does not elaborate on common use cases like website mirroring or recursive behavior, which are hinted at by the parameter schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% with clear parameter descriptions (url, output, recursive). The tool description adds no additional semantic value beyond the schema, so baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('download' or 'mirror') and the resource ('file or content from a URL'). Among sibling tools, particularly 'run_curl' which also fetches URLs, the mention of mirroring helps differentiate wget's specific capability.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like 'run_curl'. For a download and mirroring tool, it would be helpful to indicate preferred use cases or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Write content to a file, escalating to sudo if the path is protected.
| Name | Required | Description | Default |
|---|---|---|---|
| content | No | File content. | |
| filename | Yes | Destination path. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It discloses sudo escalation for protected paths, which is valuable. However, it does not mention overwrite behavior, file creation, or error handling, leaving gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is front-loaded and contains only essential information. Every word earns its place with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given few parameters and no output schema, the description covers core purpose and a key behavior (sudo). However, it omits important details like whether the file is overwritten or appended, and what happens on failure, making it minimally complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
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 context for the filename parameter (sudo escalation) but provides no additional semantics for the content parameter beyond the schema's 'File content.'
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb 'write content to a file' and clearly identifies the resource. It distinguishes from sibling tools like read_file (reading) and run_* (command execution) by core action. The mention of sudo escalation adds specificity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for writing files, but provides no explicit when-to-use or when-not-to-use guidance. It does not mention alternatives or exclusions, relying on sibling names for differentiation.
