Server provides 7 well-named tools with clear verb-noun patterns (search_code, get_file, list_repos). Descriptions are present and substantive (100-200 chars typical), explaining WHAT each tool does and WHEN to use it. Input schemas are visible with typed parameters and descriptions. However, output schemas are NOT documented, LLMs cannot predict what fields to expect from search results or file retrieval. Error handling guidance is absent; tools do not indicate what to do on failure (retry? lookup alternatives?). Parameter constraints are incomplete: search tools accept 'limit' but no min/max bounds are stated; 'repo_path' accepts SQL LIKE patterns but this is buried in description text, not formalized as a constraint. No tool annotations (readOnlyHint/destructiveHint) despite clear risk profiles. fetch_package is marked WRITE but lacks confirmation/dry-run pattern for safety.

• Document output schemas for all tools. For search_* tools, specify: { results: [{ repo_path, file_path, symbol_name, symbol_kind, score, snippet }], total_count, next_cursor }. For get_file, specify: { repo_path, file_path, content, language, size_bytes }.
• Add error recovery guidance to each tool description. E.g., search_code: 'If no results found, try search_docs or broaden the query. If repo_path is invalid, call list_repos first to see available repositories.'
• Constrain numeric parameters formally. Add to schema: limit { type: integer, minimum: 1, maximum: 100, default: 10 }. Update description: 'Number of results to return (1 - 100, default 10).'
• Add confirmation pattern to fetch_package. Introduce a dry_run parameter (boolean, default true) so agents can preview what will be indexed before committing. Document idempotency: 'Calling with the same package/version twice is safe, the second call updates the index.'
• Declare tool annotations in schema. Add readOnlyHint: true to search_code, bm25_search, search_docs, search_github, get_file, list_repos. Add destructiveHint: true to fetch_package.
