Server has 10 tools with basic schemas and descriptions, but significant gaps limit production readiness. All tools have descriptions (10-50 chars, below ideal 50-200 char baseline), and input schemas are present with type definitions. However, descriptions are generic and lack actionable context for LLM selection. No output schemas documented. Error handling is minimal, tools throw raw errors without recovery guidance. Parameter descriptions exist but lack constraints (enums, ranges, formats). No tool annotations (readOnlyHint, destructiveHint). Naming is verb-first and clear, but composition issues exist: send_message_with_keyboard and edit_message_reply_markup are narrow variants that could be unified. Security concern: no visible permission gates or audit logging.

• Expand tool descriptions to 50-200 chars. Example: 'send_message' → 'Send a text message to a Telegram chat. Use this for simple notifications. For interactive buttons, use send_message_with_keyboard instead. Supports HTML, Markdown, and MarkdownV2 formatting.'
• Document output schemas for all tools. Example: send_message returns {message_id: string, chat_id: string, date: number, text: string}. This enables tool chaining and LLM planning.
• Convert parse_mode to an enum constraint: enum: ['HTML', 'Markdown', 'MarkdownV2']. Add range constraints to timeout (1-300 seconds) and offset (≥0). Replace free-form descriptions with formal JSON Schema constraints.
• Add tool annotations: mark send_* and edit_* tools with destructiveHint=true; mark get_updates with readOnlyHint=true; mark send_message with idempotentHint=true (if Telegram deduplicates by message_id). This guides agent safety and planning.
• Enhance error messages with recovery guidance. Example: 'File not found: /path/to/file (resolved: /full/path). Check the path and try again, or use download_telegram_file to fetch from Telegram first.' Categorize errors as retryable (network timeout) vs. user-fixable (invalid chat_id).
