This server exhibits severe definition quality issues across nearly all 19 tools. While tool names follow verb_noun convention (spotify_get_*), descriptions are superficial and lack actionable guidance. Most critically, NO tools have input schemas beyond optional market parameters, 17 of 19 tools declare empty input objects {} despite accepting no parameters. Parameter descriptions are absent. Output schemas are completely undocumented; tools return raw JSON or plain text with no structure guidance for LLMs. Error handling is minimal (generic 'No track playing' messages). The tool set exhibits massive redundancy: 6 tools extract single fields from the same API endpoint (/me/player/currently-playing), violating the single-responsibility principle. This forces LLMs to reason about which granular tool to call rather than composing higher-level operations. No security considerations, no pagination, no rate-limit guidance.

• Consolidate the 17 granular single-field tools into 2-3 higher-level tools: (1) get_current_track_full (returns all metadata as structured JSON), (2) get_track_progress (returns progress_ms, duration_ms, progress_percentage, time_remaining_ms in one call). This reduces cognitive load on LLMs and eliminates redundant API calls.
• Add output schema documentation to every tool. For get_current_track_full, document: {track_name: string, artist_names: string[], album_name: string, duration_ms: number, progress_ms: number, device_name: string, track_uri: string, album_art_url: string, explicit: boolean, popularity: 0-100}. For get_track_progress, document: {progress_ms: number, duration_ms: number, progress_percentage: 0-100, time_remaining_ms: number, formatted_progress: string, formatted_duration: string, formatted_remaining: string}.
• Expand descriptions to 100-200 characters with actionable guidance. Example: 'Get the currently playing track with all metadata (name, artists, album, duration, progress). Call this first to check if music is playing; returns null if nothing is active. Use get_track_progress for real-time progress updates.'
• Implement structured error responses with recovery hints. Instead of 'No track playing', return: {error: 'no_active_playback', message: 'No music is currently playing.', recovery: 'Start playing music on a Spotify device and try again.', retryable: true}.
• Add rate-limit and timeout guidance to tool descriptions. Spotify API has rate limits; document expected latency and retry-after behavior so LLMs can plan multi-step operations without timeout failures.
