Server has 4 tools with basic schemas and descriptions, but significant gaps limit production readiness. Tool names lack clear action verbs (extract_transcript is acceptable, but generate_summary/generate_post are generic). Descriptions are present but brief (avg ~50 chars, below 194-char baseline). Parameter descriptions exist but lack actionable constraints, enums for tone/audience/voice are present but format/range guidance is sparse. No output schemas documented. Error handling and recovery guidance absent. Security concern: openai_api_key and youtube_api_key exposed as optional parameters (should use server-side injection). No tool annotations (readOnlyHint, etc.). Overall structure is functional but lacks production-grade polish.

• Move openai_api_key and youtube_api_key to server-side environment variables. Remove from tool parameters. Document in README how to configure via .env or secrets manager.
• Add output schema documentation for each tool. E.g., extract_transcript returns {transcript: string, language: string, duration_seconds: int, source: string}. Use JSON Schema format in tool definitions.
• Expand tool descriptions to 100-200 chars. Include WHEN to use, prerequisites, and output summary. E.g., 'Extract the full transcript from a YouTube video. Requires a valid video URL. Returns transcript text, language code, and video duration. Use this as the first step before summarizing.'
• Add error handling with recovery guidance. Catch common failures (invalid URL, transcript unavailable, API rate limit) and return actionable messages: 'Transcript unavailable for this video. Try: (1) verify the URL is correct, (2) check if captions are enabled, (3) try a different video.'
• Add readOnlyHint: true to all tool definitions to signal they are safe to retry and have no side effects. This enables clients to optimize retry logic and caching.
