Strong foundation with 8 well-named tools following verb_noun convention (search, fetch, search_code, get_code_context, find_symbol, get_file_outline, get_index_status, refresh_index). All tools have descriptions (avg 120 chars, within 10-1024 baseline). Input schemas present with type definitions and constraints (enums, min/max, patterns). Tool annotations correctly applied (readOnlyHint=true for 7 tools, destructiveHint=false). Key gaps: output schemas documented in code but not visible in provided snippet; parameter descriptions vary in quality (some excellent like search_code's pathGlob, others minimal like fetch's id); error handling guidance absent from descriptions; no recovery hints for common failure modes.

• Add explicit 'Returns' section to each tool description. E.g., search: 'Returns up to 10 document results with id, title, and url fields. Use fetch to retrieve full content.'
• Expand parameter descriptions to 50-100 chars minimum. For fetch.id, change to: 'Document ID returned by search or search_code, formatted as code:path/to/file.ts or doc:path/to/file.md. Must match the exact ID from search results.'
• Add recovery hints to descriptions. E.g., search_code: 'If no results, try: (1) broader query terms, (2) remove pathGlob filters, (3) check symbolKinds enum values, (4) call get_index_status to verify index is built.'
• Document refresh_index safety. Add: 'Safe to call during queries; rebuilds in-memory index without modifying repository files. Blocks until complete. Returns updated index statistics.'
• Clarify pagination strategy. Add to search and search_code: 'Results are ranked by relevance. To retrieve more results, refine your query or adjust topK parameter (search_code only). No cursor-based pagination available.'
• Add tool composition hints to server instructions. E.g., 'Typical workflow: search_code → get_code_context → fetch. Use find_symbol for definition lookups, get_file_outline for imports/structure.'
