SEAT has 6 tools with clear verb-noun naming (create_tool, list_tools, search_tools, get_tool, execute_tool, delete_tool). All tools have descriptions (10 - 200 chars, within baseline range). Input schemas are present with type declarations and parameter descriptions. However, output schemas are not documented, responses reference ToolResponse but the actual field structure is not visible in the provided code. Error handling is minimal; no recovery guidance or actionable error messages. Security concerns: execute_tool accepts arbitrary 'input_data' (object type) with no validation, and delete_tool is destructive without confirmation. Composition is sound, tools are single-responsibility and chainable via UUIDs.

• Document the complete ToolResponse schema with all fields, types, and nested structures. Include which fields are required for chaining (e.g., tool_id for execute_tool).
• Replace 'input_data' object type with a documented schema or enum of valid field names. Add validation to reject unknown fields and return 'Invalid field: X. Valid fields are: [list]'.
• Add limit and offset parameters to list_tools and search_tools. Cap results at 50 and document the limit in descriptions.
• Implement confirmation step for delete_tool: add a 'confirm=true' parameter and return 'Tool marked for deletion. Call delete_tool(tool_id, confirm=true) to finalize.' on first call.
• Add error classification to create_tool and execute_tool responses: return structured errors with 'code' (VALIDATION_ERROR, EXECUTION_TIMEOUT, etc.), 'message', and 'recovery_hint' fields.
