Critical gaps across all dimensions. Two tools with minimal descriptions (13-14 chars, well below 20-char floor). No input parameter descriptions visible, parameters lack type info beyond 'integer' for one tool. No output schemas documented. Tool definitions appear inferred from Spring-AI annotations rather than explicit registration. No error handling guidance, no security considerations, no composition patterns. This is a skeleton implementation.

• Expand tool descriptions to 50-200 chars. Example: 'get_kook_announcements: Retrieve all active announcements from the Kook platform. Returns a paginated list of announcement objects with ID, title, content, and creation date. Use this to discover available announcements before fetching a specific one by ID.'
• Add parameter descriptions. For 'id' in get_kook_announcement: 'The unique numeric identifier of the announcement to retrieve. Obtain this from get_kook_announcements() results or from a Kook announcement URL.'
• Document output schemas explicitly. Specify: 'Returns an array of objects with fields: {id: integer, title: string, content: string, created_at: ISO8601 string, author: string}' for get_kook_announcements.
• Implement pagination for get_kook_announcements. Add 'limit' (1-100, default 20) and 'offset' (default 0) parameters. Return total_count so agents know if more results exist.
• Add error handling guidance. Document: 'Returns 404 if announcement ID not found. Returns 429 if rate limited (retry after 60s). Returns 500 on service error (retryable).' Include recovery hints in error messages.
