Server Quality Checklist
Latest release: v3.13.0
- Disambiguation5/5
Each tool has a clearly distinct purpose, from codebase analysis to document writing and search. Even similar tools like search_docs, search_bugfixes, and search_by_type are differentiated by scope and description, eliminating ambiguity.
Naming Consistency5/5All tool names follow a consistent verb_noun pattern in snake_case (e.g., analyze_codebase, get_index_stats, write_api_doc). This uniformity makes it easy to predict tool functionality from its name.
Tool Count4/530 tools is high but justified by the scope of the server, which covers analysis, search, writing, indexing, and project management. Some tools could potentially be merged (e.g., search_by_type with search_docs), but overall the count is reasonable for the intended functionality.
Completeness4/5The tool set covers the full knowledge management lifecycle: analysis, classification, writing, indexing, search, and session management. Minor gaps exist, such as the lack of explicit deletion tools for documents or projects, but the core workflow is well-supported.
Average 4.7/5 across 30 of 30 tools scored.

How to sync the server with GitHub?
Servers are automatically synced at least once per day, but you can also sync manually at any time to instantly update the server profile.
To manually sync the server, click the "Sync Server" button in the MCP server admin interface.
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
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Declares read-only nature, scope (knowledge repo inside Docker volume), and caching behavior. No contradiction with missing annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with a clear intro line and bullet points; covers key aspects without excessive verbosity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Mentions output structure and integration with execute_cleanup. Output schema covers return values. Missing prerequisites but overall adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Describes the single optional parameter briefly ('Target project name (optional)'), but lacks detail on how it affects analysis. Schema has no descriptions, so description adds minimal value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Explicitly states 'Analyse the knowledge repo for structure issues, duplicates, and misplaced files' and distinguishes from siblings like classify_documents and check_knowledge_quality.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides specific when-to-use guidance: for classification use classify_documents, for simpler quality check use check_knowledge_quality, and notes that the report is cached for execute_cleanup.
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?
Describes the workflow (git pull then re-index only changed files), notes it's a no-op if up-to-date, and indicates what returns. Lacks explicit mention of network usage or potential side effects, but covers main behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Description is concise, uses bullet points for clarity, and front-loads the main purpose. Every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema, the description covers prerequisites, behavior variations, and return states. Could elaborate on project parameter usage, but overall sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter 'project' is only described as 'Target project name (optional)', which adds no meaning beyond the schema's type and default. With 0% schema coverage, the description should provide more context, e.g., how project filtering works or what default project is used.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (pull and re-index), the trigger (after pushing .md files), and distinguishes from the sibling tool 'reindex' by specifying when to use each.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to call (after pushing .md files), when not to (use reindex for local writes), and mentions the prerequisite MCP_GIT_REPO_URL configuration.
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?
No annotations provided, but description declares read-only, no side effects, and lists return fields. Some missing details like permissions or error handling, but sufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with paragraphs and bullet points, concise with essential information. Slightly verbose in returning details, but acceptable.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
In context of one optional parameter and output schema, description covers purpose, usage, and return values completely.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but description adds meaning for 'project' as optional target project name. Adequate but not extensive.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it shows vector index statistics, is read-only, and distinguishes itself from sibling tool check_knowledge_quality.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use (check chunk counts, verify reindex, inspect config) and when not to (use check_knowledge_quality for quality issues), providing clear alternatives.
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?
With no annotations provided, the description carries the full burden. It discloses that the tool is read-only, makes a single network request using git ls-remote, and does not modify files. However, it does not mention potential network failures or rate limits, which are minor omissions for a simple check.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and well-structured: a clear one-line summary, followed by detailed behavioral notes in a single paragraph, and a bullet-like list of return values. Every sentence adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters and no annotations, the description provides all necessary information: purpose, behavior, usage guidance, and return values. The presence of an output schema (as indicated by context signals) further reduces the need to describe return structure in detail.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has no parameters, and schema coverage is 100% (empty). The description adds value by explaining the return format ('Up to date' message or version number with upgrade command), which is beyond the schema. Baseline for zero parameters is 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool checks for a newer Flaiwheel version on GitHub. It includes a specific verb ('check') and resource ('Flaiwheel version'), and distinguishes itself from sibling tools, none of which serve a similar update-checking purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly says when to use the tool: 'when you suspect Flaiwheel may be outdated, or periodically to keep the server current.' Although it does not mention when not to use it or alternatives, the context of sibling tools doesn't imply any overlapping functionality, so the guidance is sufficient.
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?
With no annotations provided, the description fully bears the burden of behavioral disclosure. It explicitly declares 'Read-only', which is the key behavioral trait for a list operation. It also describes the return value in detail, including the per-project summary and the empty state behavior. No side effects or auth requirements are mentioned, but for a read-only list, this is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and well-structured: a single sentence stating the core functionality, then a 'Use to' section, and a 'Returns' section. Every sentence adds value, with no redundancy or unnecessary detail. It is front-loaded with the main purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given zero parameters, no annotations, and the presence of an output schema, the description is complete. It explains the output per project (name, chunks, quality score, docs path, git repo URL) and the behavior when no projects are registered. No gaps remain for an agent to effectively use this tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameters, and schema description coverage is 100% vacuously. The description adds no parameter-specific information, but with no parameters to describe, a baseline score of 4 is appropriate as the description compensates by explaining the output.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description uses the specific verb 'list' and the resource 'projects', clearly stating it lists all registered projects with chunk counts and health stats. It distinguishes itself from the sibling tool 'get_active_project' by noting that the latter checks only the active project, 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 Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly states when to use the tool ('to check which projects exist...') and provides a clear alternative ('Use get_active_project() to check only the active project'). It also mentions the behavior for empty projects. While it could include explicit 'when not to use' guidance, the context is sufficient for an agent.
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 details the read-only nature, the resolution logic, git log execution, return format, and error hints (empty result for non-git checkout). It adds substantial behavioral context beyond annotations (none provided).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with a clear summary, structured Args/Returns sections, and each sentence adds value. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the output schema exists, the description covers the return format and error cases. It explains the tool's purpose, parameters, and behavior comprehensively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description explains all three parameters: entity_id (frontmatter id), limit (max commits, default 20, max 200), and project (optional). This adds meaning beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool returns git history for a document, using a specific verb (Return) and resource (git history of the document). It distinguishes from siblings by focusing on historical timeline, unlike search or write tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly provides a use case: 'Use this to answer "what was true at time T?"' and explains why git history is used. It does not explicitly mention when not to use or name alternatives, but the context is clear.
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?
Discloses side effects (file creation, indexing, git push, overwrite behavior). Without annotations, this provides substantial transparency, though could mention permission requirements or failure modes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with summary, bullet-like side effects, usage guidance, and parameter list. Every sentence adds value, though slightly verbose for the parameter descriptions.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers all key aspects: purpose, side effects, usage, alternatives, parameters, and return values. Suitable for a complex tool with 7 parameters and missing output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema coverage, the description adds value by explaining each parameter's purpose (e.g., 'decisions: Key architectural decisions made and why'). Provides enough context for correct usage, though lacks examples or formats.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the tool creates architecture documents, indexes, and auto-pushes. Explicitly differentiates from siblings by naming alternative tools for other doc types.

Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use (system design, ADRs, component relationships) and when not to use by referencing siblings like write_api_doc, write_best_practice, write_bugfix_summary.
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?
No annotations are provided, so the description carries full burden. It discloses side effects (creates file, indexes, pushes to git, overwrites existing). However, it omits details about authorization needs, error handling, or what happens if auto-push fails.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a summary, side effects, usage guidelines, and args list. It is concise but could be slightly tighter (e.g., 'Args:' could be merged with the preceding list). Overall, every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 6 parameters (4 required), the presence of an output schema, and no nested objects, the description covers purpose, side effects, usage, and args. It lacks details on input format specifics (e.g., is markdown expected?) but is otherwise complete for an agent to use the tool effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has no descriptions for any parameters (0% coverage). The description compensates by explaining each parameter in plain English: title, context, rule, rationale, examples, project. This adds semantic meaning beyond the schema's type/title information.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb-resource combination: 'Create a coding standard or best practice document, index it, and auto-push.' It clearly identifies the tool's purpose and distinguishes it from sibling tools like write_architecture_doc and write_bugfix_summary.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?

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?
With no annotations, the description fully discloses behavior: read-only, lists recognized relation keys, explains output format (Markdown with truncation and not-found hints), and describes how relations are declared in frontmatter. This exceeds expectations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a summary first, then a YAML example, recognized keys, args, and returns. It's longer but each part adds value. Minor conciseness issues: the example could be shorter, but overall front-loading is effective.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity and that an output schema exists, the description is complete: it explains behavior, truncation, not-found hints, recognized keys, and references an alternative tool. No gaps in context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the description explains entity_id as the frontmatter 'id' value and project as an optional target project name, adding meaning beyond schema types and defaults. It could be more explicit about project's role, but it's good.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?

Explicitly advises calling this tool before write_test_case() to avoid duplicates. References an alternative (search_by_type) and clarifies when this tool should be used.
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?
No annotations provided, so description carries full burden. It lists side effects: creates directory, optionally clones git, runs index, binds session. Notes idempotent. Missing details like synchronous vs async index, but sufficient for transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured: summary, side-effects, usage guidance, Args, Returns. Front-loaded with key info. Returns section slightly vague ('Project name, chunk count...') but overall concise and efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given complexity (6 params, mutation with side effects, output schema exists), the description covers all essential aspects: behavior, all parameters, returns, and distinguishes from siblings. No gaps identified.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage, so description must compensate. It provides full Args section explaining each parameter: name (short identifier, no spaces), git_repo_url (HTTPS, optional), git_branch (default main), display_name (optional label), git_auto_push (default true), git_sync_interval (default 300s). Adds significant meaning beyond schema titles.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Register and initialise a new project in Flaiwheel.' It specifies the verb (register/initialize), resource (project), and scope (new project). It distinguishes from siblings like set_project (switch) and list_projects (list).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicit guidance: 'Call once per project. Use set_project() to switch between already registered projects. Use list_projects() to see what exists.' Also notes idempotency, so safe to call again if exists.
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?
With no annotations, the description carries the full burden and discloses key side effects: overwrites existing files, indexes into vector store, and auto-pushes to git. It also describes return values. However, it could mention potential failure modes for auto-push or permission requirements, but overall it is transparent given the context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is structured with clear sections: main purpose, side effects, usage guidelines, parameter list, and returns. It is front-loaded with the most critical information and every sentence adds value with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the 8 parameters (5 required) and no annotations, the description provides sufficient context for an agent to select the tool and fill parameters correctly. It covers side effects, alternatives, and return format, and the presence of an output schema further reduces the need to describe return values in detail.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It provides natural-language explanations for all 8 parameters (e.g., 'Short title', 'URL path', 'HTTP method'), adding meaning beyond the schema's type definitions. Though thorough, it could clarify the format for request_schema and response_schema more precisely.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly instructs to call at the END of every session and to use get_recent_sessions at the start of the next session, providing clear when-to-use guidance with an alternative tool.
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?
Since no annotations are provided, the description fully discloses behavior: it is read-only with no side effects, returns ranked chunks with specific fields, and prompts a follow-up action. This meets the high bar for transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-organized with sections (purpose, usage, Args, Returns) and every sentence adds value. No redundancy; it is appropriately concise for the information conveyed.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (3 params, simple return schema), the description covers purpose, usage, parameters, return format, and follow-up actions. No gaps identified.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description adds meaning to all three parameters: query is 'Description of the current problem or error message', top_k has a default, and project is optional. This compensates fully for the schema gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Search only bugfix summaries for similar past problems', providing a specific verb and resource. It also distinguishes from the sibling tool search_docs by noting its focused scope.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicit guidance is given: prefer this over search_docs when debugging, and use search_docs for broader queries. Also instructs to call write_bugfix_summary when no matches are found.
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?
With no annotations, the description fully discloses behavior: read-only, no side effects, and describes the return format including how 'no results' is handled with a rephrasing suggestion.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with clear sections: purpose, usage guidelines, args, returns. Every sentence is concise and contributes value, no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite an output schema existing, the description covers all necessary context: purpose, usage rules, parameter semantics, and return details including edge cases. Complete for a search tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage, but the description explains each parameter: query as natural language, top_k with default and usage advice, and project as optional with default behavior, adding significant meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Semantic search over the ENTIRE project knowledge base' with 'Read-only, no side effects', distinguishing it from sibling tools like search_bugfixes, search_by_type, and search_tests.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly advises 'Use this ALWAYS before writing or changing code' and provides clear alternatives: 'Prefer search_bugfixes() when debugging...', 'Use search_by_type() when you know the category.', 'Use search_tests() when looking for test coverage.'
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?
No annotations provided, but description fully discloses in-memory only, no file modification, per-connection binding, and return value details for success and failure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with bullet points, front-loaded with primary purpose, no wasted words. Every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Single parameter with output schema; description explains purpose, usage pattern, return values, error handling, and differentiates from many sibling tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage, but description adds that 'name' must be a registered project from list_projects(), providing essential context beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it binds all subsequent tool calls to a specific project, and distinguishes from sibling tools setup_project (create new) and get_active_project (check binding).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly instructs to call at the START of every session, and explains when to use setup_project or get_active_project instead. Also clarifies override behavior with project= parameter.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
