The server defines 5 tools with reasonable naming conventions (verb_noun patterns: SEND_MESSAGE, GET_CHANNEL_INFO, FORWARD_MESSAGE, PIN_MESSAGE, GET_CHANNEL_MEMBERS). All tools have brief descriptions present. However, parameter schemas are partially visible from the provided input specs, and the actual source code for schema definitions (the individual tool files) is not shown, making it impossible to verify complete schema implementation, type constraints, or output documentation. Descriptions are present but generic (30-60 chars on average). Parameter descriptions exist but are minimal. No evidence of output schemas, error handling guidance, or recovery paths. No tool annotations visible. The server lacks structured error responses and actionable error messages. Security consideration is present (uses dotenv for secrets) but not explicitly validated in tool definitions.

• Document output schema for each tool. Example: SEND_MESSAGE returns { message_id: string, timestamp: string, chat_id: number }. GET_CHANNEL_MEMBERS returns { members: [{id, username, is_admin}], total_count: number }. This enables chaining and LLM planning.
• Expand parameter descriptions to include constraints, examples of valid values, and guidance. E.g. for chatId: 'The Telegram chat ID (numeric, e.g., -1001234567890) or channel username (string, e.g., @mychannel). Use username when available; numeric IDs are harder for humans to read.'
• Add tool annotations: SEND_MESSAGE, FORWARD_MESSAGE, PIN_MESSAGE should all have destructiveHint: true; GET_CHANNEL_INFO and GET_CHANNEL_MEMBERS should have readOnlyHint: true.
• Document error scenarios and recovery paths. E.g. SEND_MESSAGE can fail if: 'User lacks permission (retry with admin approval)', 'Chat not found (verify channel exists)', 'Message text too long (suggest chunking)', 'Rate limited (wait and retry after 5 seconds)'.
• Add dependency hints in descriptions. E.g. GET_CHANNEL_MEMBERS: 'Call GET_CHANNEL_INFO first to confirm the channel exists and your permissions.'
• Clarify the relationship between GET_CHANNEL_INFO and GET_CHANNEL_MEMBERS. Are they sequential discovery tools, or does one make the other redundant? State this explicitly.
• For GET_CHANNEL_MEMBERS, document pagination if limit < total_count. Add guidance: 'If total_count > limit, use offset parameter (if supported) or call multiple times with different offsets. Default limit is 10; max is 50 per Telegram API.'
