All 4 tools have descriptions and basic schemas, but critical gaps undermine quality. Tool names lack clear verb-noun structure (plex_to_deck, plex_playlist_to_automix are compound actions). Parameter descriptions are present but generic, no constraints, ranges, or format guidance. Output schemas are completely undocumented; callers cannot predict response structure. Error handling is minimal (generic 'success': false). The code snippet shows incomplete implementation (line ends mid-function with 'shu' typo), suggesting unfinished work. Cross-server dependencies (importing from virtualdj_mcp, plex_mcp) are hardcoded and fragile.

• Document output schemas for all tools. Example: plex_to_deck returns {success: bool, plex_result: {title, artist, album, file}, vdj_deck: int, message: str} or {success: false, error: str}.
• Add enum constraints to parameters. Change 'search_type' description to 'Type of search: one of track|album|artist' and add JSON Schema enum: ["track", "album", "artist"].
• Rename tools to verb_noun pattern: load_plex_track_to_deck, queue_plex_playlist_to_automix, save_virtualdj_mix_to_plex, load_multiple_plex_tracks_to_decks.
• Add min/max bounds to numeric parameters. E.g., 'deck_id: VirtualDJ deck (1-8, default 1)' and 'limit: Maximum tracks to load (1-100, default 50)'.
• Implement error classification. Return {success: false, error: str, error_type: 'not_found'|'invalid_input'|'service_unavailable', recovery: 'Try search_plex() first'} to guide LLM retry logic.
