Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v1.0.0
Disambiguation5/5
Each tool targets a distinct operation: file management (create_directory, read_file, write_file, edit_block, move_file), process management (start_process, interact_with_process, read_process_output, kill_process, list_processes, list_sessions), search (start_search, get_more_search_results, list_searches, stop_search), configuration (get_config, set_config_value, get_prompts, get_usage_stats, get_recent_tool_calls, give_feedback_to_desktop_commander), and PDF creation (write_pdf). There is no functional overlap despite high number of tools.
Naming Consistency5/5
All tool names follow a consistent verb_noun snake_case pattern (e.g., create_directory, edit_block, force_terminate, get_config, start_process). No mixing of conventions or irregular naming.
Tool Count4/5
26 tools is slightly high but appropriate for a comprehensive desktop commander server covering file operations, process management, search, configuration, and PDF creation. Each tool serves a clear purpose, though some consolidation could reduce count slightly.
Completeness3/5
The tool set covers file CRUD but notably misses delete (no delete_file or remove_directory) and copy operations. Process management lacks suspend/resume. Search and configuration are well-covered. The missing delete and copy operations are significant gaps for a file management server.
Average 4.3/5 across 26 of 26 tools scored. Lowest: 2.7/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description identifies the tool as destructive, matching annotations, and specifies it targets a 'terminal session'. However, it does not disclose required permissions, potential side effects, or how termination is performed.
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?
Two sentences, no redundancy. The second sentence about referencing is marginally useful but still concise.
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?
Lacks explanation of what constitutes a terminal session, how to obtain a PID, and how this tool differs from the similar 'kill_process'. The presence of siblings demands more context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description does not mention the 'pid' parameter or how it identifies the session. With 0% schema coverage, the description fails to clarify the parameter's meaning or format.
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 it force terminates a running terminal session, but it does not differentiate from the sibling tool 'kill_process', which likely has similar functionality.
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 on when to use this tool versus alternatives like 'kill_process' or 'interact_with_process'. The only additional note is about referencing the command, not usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already set destructiveHint=true, so the description's 'forcefully terminate' adds some context but does not disclose additional behaviors like potential data loss or irreversibility. It aligns with annotations but adds little extra.
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 sentences, mostly concise. The third sentence about referencing as 'DC: ...' is tangential and adds length without aiding tool 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 simple tool with one parameter and no output schema, the description covers purpose and caution adequately. However, it could include a brief note on prerequisites (e.g., PID must exist) for completeness.
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 has 0% description coverage; the description only mentions 'by PID' without explaining what PID means or how to obtain it. This adds minimal value beyond the parameter name.
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 'Terminate a running process by PID.' This is a specific verb-resource pairing that distinguishes the tool from siblings like 'interact_with_process' or 'force_terminate'.
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?
While the description warns 'Use with caution', it does not specify when to use this tool versus alternatives (e.g., 'interact_with_process' for graceful termination) or when not to use it. No explicit context or exclusions provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotation declares readOnlyHint: true, but the description states 'retrieve and execute it', implying execution with potential side effects. This is a clear contradiction. No further behavioral details are provided beyond the contradictory execution claim.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with sections and clear formatting, but it is somewhat verbose. It could be more concise while retaining essential 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 usage and parameter values adequately, but lacks details about return values, error handling, and what 'execution begins immediately' means. Given no output schema, the agent might be left uncertain about results.
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 0%, so the description must compensate. It does so by listing all valid prompt IDs mapped to numbers and specifying the action enum value. This adds meaning beyond the schema's bare string definitions.
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 retrieves and executes a specific Desktop Commander onboarding prompt by ID. It distinguishes from sibling tools by focusing exclusively on onboarding prompts and providing a direct numbered list.
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 explicit mapping from user selections (1-5) to prompt IDs and the action parameter. It effectively tells the agent when to use this tool during onboarding. However, it does not explicitly state when not to use it or mention alternative tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true; description adds value by detailing the config structure (fields) and return format (JSON), enhancing transparency beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is somewhat verbose with a field list but is front-loaded with the main action. The meta instruction about 'DC: ...' adds length without core value.
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 read tool with one optional parameter, the description covers the return value comprehensively by listing all config fields, making it complete enough.
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?
The only parameter 'origin' is not described in the description, despite having an enum. Schema coverage is 0%, and the description fails to explain its purpose or values.
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 'Get the complete server configuration as JSON,' specifying a unique verb and resource, and it distinguishes from sibling tools like set_config_value.
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 usage for reading config but lacks explicit when-not or alternative tool guidance. The mention of 'DC: ...' is a weak usage hint.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint: true. The description adds useful behavioral context: history is kept in memory (last 1000 calls, lost on restart) and excludes self-tracking and meta/query tools.
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?
Well-structured with a clear purpose sentence, bullet list of use cases, and a note. The final sentence about 'DC' seems unnecessary and could be removed for conciseness.
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?
Provides good context about memory and exclusions, but lacks parameter descriptions and output format details. With no output schema, the description should clarify the return structure.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description does not explain any of the three parameters (since, toolName, maxResults). The agent must rely solely on the schema, which only provides name and type.
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 retrieves recent tool call history with arguments and outputs, and that it returns a chronological list from the current session. It is distinct from sibling tools like read_file or list_directory.
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?
Explicitly lists use cases (onboarding, recovering context, debugging) and a limitation (does not track its own calls or meta tools). However, no direct comparison to alternatives is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so description adds value by specifying what is returned (summary, success/failure rates, performance metrics), providing context beyond the structured fields.
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 concise and front-loaded, with two clear sentences about purpose and output. The third sentence about referencing is slightly meta but not wasteful.
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 tool with no params and no output schema, the description sufficiently covers purpose and output details, though the exact scope (real-time vs historical) is not clarified.
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?
No parameters exist, so schema coverage is 100%. Baseline for 0 params is 4; the description does not need to add param info.
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 'Get usage statistics for debugging and analysis' with specific verb and resource, and distinguishes from sibling tools like get_config and get_prompts by focusing on usage metrics.
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 only mentions how to reference the tool in instructions, but does not provide guidance on when to use it versus alternatives (e.g., get_recent_tool_calls) 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.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations are neutral (readOnlyHint=false, destructiveHint=false). Description adds gracefulness, background process, and 5-minute cleanup behavior. No contradiction.
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?
Description is mostly concise, but includes extraneous meta-comment about referencing format, which adds little value for tool selection.
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?
Covers purpose and behavior well, but lacks parameter guidance. For a simple one-param tool, it is moderately complete.
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 0% so description bears full burden. The single required parameter 'sessionId' is not mentioned or explained in 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 clearly states the tool stops an active search using specific verbs and resource. It distinguishes from sibling 'force_terminate' by describing a graceful stop.
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 says when to use it: when found what you need or search is taking too long, and compares to force_terminate. Lacks explicit when-not-to-use but context is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, signaling potential deletion or modification. The description adds context about path normalization and allowed directories but does not disclose behavior if destination already exists (e.g., overwrite or error). This is a notable gap for a destructive 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 concise with two short paragraphs. The first sentence immediately states the core purpose. The second paragraph contains essential usage notes. No unnecessary information, and structure is front-loaded effectively.
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 simple two-parameter schema and lack of output schema, the description covers purpose, constraints, and path guidance. It lacks details about return values, error conditions, or behavior on conflict, but overall it provides sufficient context for basic usage.
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 has 0% description coverage for both parameters. The description clarifies that source and destination are paths and recommends absolute paths, adding some guidance. However, it does not explicitly describe each parameter's expected format (e.g., source must be an existing file/directory) or constraints beyond paths.
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 explicitly states the tool moves or renames files and directories, using specific verbs and resources. It clearly distinguishes from sibling tools like write_file or create_directory by focusing on relocation/renaming rather than creation or content modification.
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 explicit guidance on using absolute paths, warnings about relative and tilde paths, and mentions that source and destination must be within allowed directories. However, it lacks explicit 'when not to use' or comparison to alternatives like copy instead of move.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide readOnlyHint=true, confirming no side effects. Description adds return format details (PID, CPU, memory), adding value beyond annotations.
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 sentences, no fluff, front-loaded with key purpose. Every sentence adds value.
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?
Tool is simple; description covers purpose and return fields. Could mention lack of filtering, but complete for a list-all tool.
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?
No parameters; baseline for 0 params is 4. Description does not need to elaborate on params.
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?
Description clearly states 'List all running processes' and specifies returned fields (PID, command name, CPU, memory), distinguishing it from sibling tools like kill_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?
Implied usage for listing processes, but no explicit guidance on when to use vs alternatives or when not to use. Sibling tools like 'kill_process' suggest broader context could be added.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true. Description adds detail about returned fields and runtime, enhancing understanding beyond annotations. No contradictions.
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?
Succinct three-sentence description: main purpose, details, and usage hint. No redundancy, every sentence adds value.
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?
Adequately covers the tool's functionality for a simple read-only list command, mentioning output fields. Without output schema, description compensates well, though it could briefly note if no results are shown.
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?
Input schema has no parameters, so schema_description_coverage is 100%. Description adds no parameter info, which is expected. 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?
Clearly states 'list all active searches' with specific fields (IDs, types, patterns, status, runtime). Differentiates from sibling list_sessions by noting similarity, making 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?
Provides context for managing multiple searches and a comparison to list_sessions, implying when to use this tool. However, lacks explicit exclusions or alternative guidance for related tools like start_search or stop_search.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide readOnlyHint=true, and the description elaborates with offset behavior, output protection, smart features, and detection states. No contradiction; adds significant value beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with sections and examples, but somewhat verbose. Redundant phrases like 'This command can be referenced...' could be removed. Front-loaded purpose, but length could be trimmed without losing clarity.
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?
Covers tool purpose, all parameters except verbose_timing fully, output protection, and detection states. No output schema, but describes return format partially with examples. Mostly complete for the tool's complexity.
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 0%, so description must compensate. It thoroughly explains offset and length with examples, mentions timeout_ms, but does not explicitly describe pid or verbose_timing. Partial coverage, so score 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?
Clearly states 'Read output from a running process with file-like pagination support.' The verb 'read' and resource 'output from a running process' are specific and unambiguous. Distinguishes from siblings like read_file and interact_with_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?
Provides detailed parameter usage with examples, including offset semantics and timeout. Does not explicitly state when not to use, but the context and sibling tools imply alternatives. The description gives clear guidance on how to use the tool effectively.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses that it 'only works within allowed directories' and explains path normalization and potential issues with relative paths. The annotations indicate a non-read-only, non-destructive operation, and the description adds useful behavioral context without contradiction.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is somewhat verbose with multiple paragraphs and code formatting. While it front-loads the purpose, it could be more concise. Some details (e.g., referencing instructions) add length without critical value.
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 parameter and no output schema, the description adequately covers what the tool does and how to use it. It provides enough context for the agent to succeed, though it could briefly mention expected return values.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one parameter 'path' with no description (0% coverage). The description fully compensates by explaining the meaning of the path, when to use absolute vs relative, and normalization 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 clearly states the action: 'Create a new directory or ensure a directory exists.' It also mentions the capability to create multiple nested directories, which distinguishes it from other file operations like 'write_file' or 'edit_block'.
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 explicit guidance on using absolute paths, warns about relative and tilde paths, and mentions path normalization. It also suggests how to reference the command in instructions. However, it does not explicitly contrast with when to use alternative tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true, so it's a safe read operation. The description adds behavioral context such as workspace restrictions and path normalization details. No contradictions.
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?
Well-structured with bullet points for metadata and clear sections. Somewhat lengthy but each sentence adds value. Could be slightly more concise, but overall effective.
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 parameter thoroughly and lists expected return fields. Mentions workspace restrictions but lacks error handling details. Generally 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 0%, but the description compensates with detailed path usage guidance: absolute vs relative paths, tilde handling, and automatic normalization. This adds significant meaning beyond the schema's parameter name.
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?
Clearly states it retrieves detailed metadata about a file or directory, listing specific attributes like size, creation time, and type. Distinguishes from sibling tools like list_directory (which lists contents) and read_file (which reads content).
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 clear context on when to use: retrieving file metadata. Includes important path usage guidelines (absolute paths, normalization, tilde handling) and mentions it works only within allowed directories. Does not explicitly exclude alternatives or state when not to use.
