Strong tool definitions with clear naming, comprehensive schemas, and good descriptions. All 5 tools follow verb_noun convention (telegram_search, telegram_get, telegram_call, telegram_refresh). Input schemas are complete with type definitions and constraints. Descriptions range 80-180 chars, meeting the 10-1024 baseline. However, output schemas are not documented in the visible code, and error handling guidance is minimal. Tool composition is excellent, each tool has a single responsibility and clear chaining potential (search → get → call). Security is well-handled with token injection via config, not parameters.

• Document output schemas for all tools. For telegram_get_method and telegram_get_type, specify the structure of returned method/type objects (e.g., {name, description, parameters, returns}). For telegram_search_methods, document the result array structure and fields returned per match.
• Add error classification and recovery guidance to telegram_call_method. Example: 'If the API returns 400 (invalid parameters), review the method schema via telegram_get_method. If 429 (rate limited), retry after the Retry-After delay. If 403 (permission denied), verify bot token and chat permissions.'
• Expand telegram_refresh_schema description to explain when to call it and what happens during refresh. State whether it blocks other operations, how long it typically takes, and whether it logs progress.
• Add per-parameter constraints to telegram_call_method.parameters. Document that parameters must match the schema returned by telegram_get_method, and that unknown parameters are rejected unless TELEGRAM_ALLOW_UNKNOWN_PARAMETERS=true.
• Include chaining hints in tool descriptions. E.g., telegram_search_methods should note: 'Use results to call telegram_get_method for full schema details, then telegram_call_method to execute.'
