Single tool 'search_docs' has a basic description (54 chars) and partial input schema. Description lacks WHEN to use it, prerequisites, or return format guidance. Input schema defines 'query' and 'workspace' with types and brief descriptions, but no output schema is documented. No error handling guidance (e.g., what if docs/ doesn't exist?). Tool name is verb-based (search_) which is correct, but the implementation snippet shows the tool is incomplete, the code cuts off mid-function. No evidence of parameter validation, enum constraints, or structured output documentation. Baseline: A+ tools average 194 chars in description and 100% have documented return types; this tool has neither.

• Expand tool description to 100 - 200 chars: 'Search project documentation (README, docs/, *.md) for content matching a query. Returns matching file paths and line snippets with context. Use this to find relevant docs before asking follow-up questions.'
• Document output schema: e.g., {type: 'object', properties: {results: {type: 'array', items: {type: 'object', properties: {file: {type: 'string'}, line_number: {type: 'integer'}, snippet: {type: 'string'}}}}}, total_matches: {type: 'integer'}}}
• Add error handling guidance to description: 'If no matches found, returns empty results. If workspace path is invalid, returns error with available directories.'
• Constrain 'workspace' parameter: add description 'Absolute or relative path to project root. Defaults to current directory. Must be a valid directory.'
• Add 'limit' parameter (default 20, max 100) to cap results and prevent context window exhaustion per mxe:enforce-result-limits baseline.
