13 tools with clear verb-noun naming and mostly complete schemas. Descriptions are present but often generic (avg ~60 chars, below 194-char baseline). Parameter descriptions exist but lack detail on constraints, formats, and valid ranges. No output schemas documented. Error handling and recovery guidance absent. Security considerations (auth scopes, token handling) not visible in tool definitions. Composition is sound, tools are single-purpose and chainable via IDs.

• Document output schemas for all tools. E.g., list_videos should specify: returns {videos: [{id, title, views, watchHours, ...}], total, nextOffset}. This enables LLMs to chain tools correctly.
• Add format and range constraints to parameter descriptions. E.g., 'limit: number (1 - 100, default 50)', 'startDate: ISO 8601 string (YYYY-MM-DD)', 'cohort: enum (short|long|all)'.
• Expand tool descriptions to 100 - 200 chars. Include: what it does, when to use it vs similar tools, and any prerequisites. E.g., 'Get detailed metadata for a specific video. Call after list_videos to fetch full details. Returns title, description, tags, publish date, and performance metrics.'
• Add error recovery guidance to descriptions. E.g., 'If video not found, try list_videos to verify the ID. If sync fails, check auth_status first.'
• For write operations (import_studio_export, sync_catalog), add a dry_run parameter or document the confirmation flow. Warn in descriptions: 'This operation modifies your catalog. Ensure you have a backup.'
