CortexOS defines 7 tools with basic schemas and descriptions. All tools have names starting with action verbs (add_, search_, answer_, list_, get_) and descriptions present. However, descriptions are terse (avg ~60 chars, well below the 194-char baseline), parameter descriptions lack detail on constraints and formats, and output schemas are not formally documented. No error handling guidance, no enum constraints on optional parameters (wing, room), and no pagination support despite search_memory potentially returning large result sets. Tool composition is reasonable (single responsibility), but descriptions do not explain WHEN to use each tool or what downstream tools expect.

• Expand tool descriptions to 100 - 200 chars. For search_memory: 'Search memories by query text with optional wing/room filters. Returns matching memories ranked by relevance. Use this to find specific facts; use answer_with_memory to synthesize an answer from multiple memories.'
• Add enum constraints for wing and room parameters. Document valid values in the description or fetch them dynamically via list_wings/list_rooms. E.g., 'wing: Optional wing classification (e.g., "executive", "engineering"). Call list_wings() to see available options.'
• Document output schemas explicitly. For search_memory, specify: 'Returns {results: [{id, text, wing, room, created_at, relevance_score}], total: int, explain: string|null}'. Include this in the tool description or as a separate schema annotation.
• Add pagination to search_memory, get_conflicts, get_superseded. Accept limit (default 20, max 100) and offset parameters. Return total_count and next_offset. Cap results at 50 items by default to prevent context window exhaustion.
• Implement structured error responses. Catch exceptions and return {error: string, code: string, recovery_hint: string}. E.g., 'Invalid wing "xyz". Valid wings: ["executive", "engineering"]. Call list_wings() to see all options.'
