21 tools with complete schemas and descriptions, but quality is uneven. Naming is verb-first and clear (list_*, get_*, create_*, update_*, delete_*, run_*, search_*). Descriptions are present but brief (avg ~60 chars, well below the 194-char baseline). Parameters have types and descriptions, but many lack constraints (enums, ranges, format hints). Output schemas are not documented, LLMs cannot predict response structure. Error handling is minimal; no recovery guidance. No tool annotations (readOnlyHint/destructiveHint). Composition is good: tools are single-responsibility and chainable (e.g., list_apis → get_api → update_api_script). Security: no secrets in params (good). Overall: solid foundation, but descriptions and output documentation need expansion to meet A-grade standards.

• Document output schemas for all tools. E.g., list_apis returns [{id, name, method, path, runPath, group}]; create_api returns {id, runPath}. Include field types and whether pagination is supported.
• Expand descriptions to 100 - 200 chars. Add WHEN to use, prerequisites, and side effects. E.g., 'delete_api: Permanently removes an API endpoint. Ref can be id, name, or path. This action cannot be undone.'
• Add tool annotations: mark read-only tools with readOnlyHint=true (list_*, get_*, search_*, run_api); destructive tools with destructiveHint=true (delete_*); idempotent tools with idempotentHint=true (enable_task, disable_task).
• Constrain parameters: 'method' enum [GET, POST, PUT, DELETE, PATCH]; 'cron' with format hint 'cron expression (e.g., 0 0 * * *)'; 'enabled' as boolean with default false.
• Enhance error messages with recovery hints. E.g., if ref not found, return 'API not found. Try list_apis() to see available endpoints.' Include available options in 404 responses.
