Three tools with clear verb-noun naming (list_, get_, compose) and basic descriptions. However, critical gaps undermine production readiness: parameter descriptions are sparse or missing (e.g., 'names' array in compose lacks guidance on valid template names, case sensitivity, or error handling for invalid names); output schemas are completely undocumented (no structured response format specified); error handling is minimal (generic 'not found' errors without recovery guidance); no input validation hints or constraints documented. The 'get_template' description mentions case-sensitivity but provides no guidance on discovering valid names. Descriptions average ~100 chars, below the 194-char baseline for A+ tools. No tool annotations (readOnlyHint, etc.) despite all being read-only operations.

• Document output schemas for all three tools. E.g., list_templates returns {templates: string[]}; get_template returns {name: string, body: string}; compose returns {names: string[], body: string}.
• Add parameter descriptions: 'names' in compose should state 'Array of template names (case-sensitive, e.g. ["Node", "macOS"]). Max 10 templates per call. Invalid names are skipped with a warning.'
• Enhance error messages with recovery hints. E.g., 'Template "nodejs" not found (case-sensitive). Call list_templates() to see available names, or try "Node" instead.'
• Add readOnlyHint: true to all tool definitions to signal safety and enable client-side caching optimizations.
• Document constraints in compose description: 'Accepts 1-10 template names. Returns combined .gitignore with section headers. Skips invalid names and returns a warning list.'
