Three tools with clear naming (load_skill, read_skill_file, list_skill_files) and reasonable descriptions (100-150 chars each). All tools have input schemas with type definitions and parameter descriptions. However, output schemas are not documented in the source code, the tool implementations return unstructured responses without explicit schema declarations. Parameter descriptions are minimal (10-30 chars) and lack detail on expected formats, constraints, or error conditions. No error handling guidance visible. Tools follow a single responsibility pattern (read-only operations on skill resources), but lack pagination, result limits, and recovery hints.

• Document output schemas for all three tools. E.g., load_skill returns {type: 'object', properties: {content: {type: 'string', description: 'Markdown body of the skill'}, skill_name: {type: 'string'}}}.
• Expand parameter descriptions to 50-100 chars with format hints. E.g., 'skill_name: The unique identifier of the skill (alphanumeric, lowercase, e.g. "python-basics")' instead of 'The name of the skill'.
• Add error handling guidance to tool descriptions. E.g., 'If skill not found, returns error with available skill names. Call list_skill_files with no subdirectory to discover skills.'
• Document result limits and pagination for list_skill_files. E.g., 'Returns up to 100 files. Use subdirectory parameter to filter results and reduce response size.'
• Include dependency hints in descriptions. E.g., load_skill: 'Use this after list_skill_files to retrieve full instructions for a skill you've identified.'
