Single tool 'index_repository' has a basic description but critically lacks parameter descriptions and a documented output schema. The input schema defines two parameters (repo_path, mode) with types but no descriptions explaining what 'mode' values are valid, what 'full' means, or what the tool returns. No error handling guidance. Tool naming is acceptable (verb_noun form) but the implementation is far below production baseline. The server appears to be a code intelligence indexer, but the tool definition provides insufficient context for an LLM to use it effectively.

• Add description to 'mode' parameter: 'Indexing strategy: "full" (complete reindex, slower), "incremental" (update only changed files), or "fast" (syntax-only, no semantic analysis). Default: "full".'
• Add description to 'repo_path' parameter: 'Absolute or relative path to repository root. Must be readable. Supports symlinks. Max 4096 chars.'
• Document output schema with example: '{"status": "success"|"error", "indexed_files": <int>, "graph_nodes": <int>, "duration_ms": <int>, "error_message": <string|null>}'
• Add error handling: 'If path does not exist, return error with suggestion to verify path. If permission denied, advise checking file permissions. If timeout (>30s), suggest using mode="fast" for large repos.'
• Expand tool description to 100-150 chars: 'Index a codebase to build a semantic graph for code intelligence queries. Call this once per repo before using search/analysis tools. Supports full reindex or incremental updates.'
