13 tools with consistent naming (verb_noun pattern: netflix_*) and basic descriptions. All tools have input schemas with required fields properly declared. However, descriptions are generic (avg ~80 chars, well below the 194-char baseline for A+ tools) and lack actionable context. Parameter descriptions are minimal, most are 1-2 sentences without format constraints, ranges, or dependency hints. No output schemas documented. Error handling is absent from tool definitions. Missing idempotency guidance for write operations. Tools like netflix_search and netflix_browse_genre lack enum constraints for valid inputs (genre values, search scope). No pagination parameters despite tools returning lists (my_list, history, recommendations, continue_watching). Composition is sound, each tool has one responsibility, but chaining is weak: search returns contentId but details don't clarify what fields are returned, forcing agents to guess.

• Document output schemas for all tools. Example: netflix_search should return [{contentId: string, title: string, type: 'movie'|'show', year: number, rating: number}]. This enables agents to chain calls correctly.
• Add pagination to list tools: netflix_my_list(limit=20, offset=0) → {items: [...], total: number, hasMore: boolean}. Cap results at 50 items per call.
• Convert netflix_browse_genre 'genre' parameter to an enum: ['action', 'comedy', 'drama', 'documentary', 'thriller', ...]. Add netflix_search 'query' description: 'Search by title, actor name, director, or genre keyword. Returns up to 20 results.'
• Add idempotency guidance to write tools: 'This operation is idempotent, calling twice with the same contentId has no additional effect.' Add a dry_run parameter to netflix_add_to_list and netflix_remove_from_list for confirmation.
• Enhance tool descriptions with recovery paths: 'If netflix_auth_check returns isLoggedIn=false, call netflix_auth_clear() to reset, then follow the loginUrl. If session expires mid-operation, retry after re-authenticating.'
