AgentOS presents a well-structured set of 5 tools with clear naming conventions and comprehensive descriptions. All tools follow verb_noun naming patterns (list_tools, run_mission, resume_mission, cancel_mission, ingest_document), which is excellent for LLM parsing. Descriptions are detailed and explain WHAT the tool does, WHEN to use it, and important operational context (e.g., background task execution, idempotency semantics). However, there are significant gaps in parameter validation, output schema documentation, and error handling guidance. Input schemas are present and properly typed, but parameter descriptions lack detail about formats, ranges, and constraints. No output schemas are documented in the source code. Error handling is minimal, no guidance on recovery paths or error categorization.

• Document output schemas for all 5 tools. For list_tools, specify {tools: [{name: string, description: string, ...}], total_count: integer}. For run_mission, specify {mission_id: string, status: string, created_at: string}. For cancel_mission, specify {mission_id: string, status: string}. Add these to the tool definitions visible in app.py.
• Enhance parameter descriptions with format and constraint details. Change 'workspace_id' description from 'UUID of the workspace' to 'UUID of the workspace (36-char format, e.g., 550e8400-e29b-41d4-a716-446655440000)'. Similar updates for mission_id, document_version_id, and file_path.
• Add error handling guidance to WRITE tools. For run_mission, add: 'Returns error if workspace_id not found, mission is already running, or objective is empty. Retryable on temporary service errors. Check run_mission status before retrying.' Similar guidance for resume_mission, cancel_mission, ingest_document.
• Document conditional parameter dependencies in resume_mission. Clarify in the description: 'edited_args is required if and only if decision="edit". If decision is "approve" or "reject", omit edited_args.'
• Add pagination support to list_tools. Include optional parameters: limit (1-100, default 20), offset (default 0). Return total_count in response. Document: 'Returns paginated list of tools. For workspaces with 100+ tools, use limit and offset for efficient discovery.'
• Specify idempotency semantics explicitly. For cancel_mission, add to description: 'Idempotent, cancelling an already-cancelled mission returns success. Safe to retry on timeout.' For run_mission, clarify: 'Non-idempotent, calling twice with same mission_id will queue a second execution. Use cancel_mission before retrying.'
