The server defines 5 tools with complete input schemas and reasonable descriptions. Tool naming follows verb_noun conventions (summarize_*, get_*). However, several definition quality issues limit the score: (1) output schemas are not documented, the tools return summarized text/JSON but the response structure is not formally specified, making it difficult for LLMs to plan downstream operations; (2) parameter descriptions are present but lack detail about expected formats, ranges, and constraints (e.g., 'hint' and 'output_format' enums are documented but edge cases like 'What happens if both are omitted?' are unclear); (3) error handling descriptions are minimal, tools do not explain recovery paths or validation failures; (4) the 'cwd' parameter on multiple tools lacks validation guidance and could enable path traversal attacks if not sanitized; (5) some descriptions are vague (e.g., 'Summarize the structure of a directory' does not explain what 'structure' means, tree view? file count? size breakdown?). Strengths: tool names are action-oriented and clear; all tools have descriptions meeting the 10-1024 character baseline; schemas use proper JSON types and required fields are marked; the enum constraints for 'hint' and 'output_format' are well-defined.

• Document output schemas for all tools. Example: {summary: string, token_count: number, original_length: number, truncated: boolean, format: string}. This enables LLMs to extract fields and plan chains.
• Add error recovery guidance to each tool description. Example: 'If a file is not found, the tool returns {error: "file_not_found", available_alternatives: [...]}. Try with an alternative path or call list_files first.'
• Add explicit path validation hints to 'cwd' parameter: 'Must be an absolute path or relative to server root. Server prevents traversal above configured root.' Mention server-side sanitization to reassure LLMs.
• Add size/length constraints to parameters: 'command' ≤ 1000 chars, 'paths' array ≤ 10 items, 'content' ≤ 100,000 chars. This prevents resource exhaustion and guides LLM invocation.
• Document 'hint' enum values with examples. Replace 'Focus area for summarization' with 'Hints to guide summarization focus: security_analysis (highlight security concerns), api_surface (focus on public interfaces), error_handling (prioritize error paths), dependencies (list imports/requires), type_definitions (extract type signatures).'
• Define 'recursive' default explicitly: 'Whether to include subdirectories (default: false). When true, traverses up to 10 levels; directories in ignore list are skipped.'
• Add response schema documentation as inline examples in tool descriptions or as a separate response schema property in the MCP tool definition (if supported). Example: 'Returns: {summary: string (1-5000 chars), original_length: number, truncated: boolean}'.
