Three tools with complete schemas and basic descriptions, but significant gaps in parameter documentation and output schema clarity. Tool names follow verb_noun convention (search_, get_). Descriptions are present but generic (avg 95 chars, below 194-char baseline). Critical issue: no output schemas documented, LLMs cannot plan downstream calls or extract structured data. Parameters lack descriptions for critical fields (file_path in get_file_content has no description). Error handling returns plain text without recovery guidance. No tool annotations (readOnlyHint, etc.). Composition is reasonable (three distinct concerns), but missing pagination for search_codebase despite potentially large result sets.

• Add formal output schemas to all tools. Example for search_codebase: {type: 'object', properties: {results: {type: 'array', items: {type: 'object', properties: {file_path: {type: 'string'}, start_line: {type: 'integer'}, end_line: {type: 'integer'}, similarity_score: {type: 'number'}, content: {type: 'string'}}}}, total_count: {type: 'integer'}}}
• Add descriptions to all parameters. For get_file_content, add: 'file_path: The full path to the file relative to the codebase root (e.g., src/main.py, README.md)'
• Replace example-based descriptions with enums or patterns. Change search_codebase file_type from 'e.g., .py, .js, .md' to enum: ['.py', '.js', '.ts', '.md', '.txt'] or pattern: '^\.[a-z0-9]+$'
• Implement pagination for search_codebase: add offset/limit or cursor-based pagination; return total_count and next_cursor in response. Document in description: 'Returns up to 20 results per page. Use offset parameter to fetch additional pages.'
• Enhance error messages with recovery guidance. Example: 'File not found: {file_path}. Verify the path is relative to the codebase root. Call get_codebase_stats() to see indexed files.' Add readOnlyHint: true to all three tools in the Tool definition.
