Lists multiple specific concrete actions and artifacts: 'client.listen.v2.createConnection() / connect()', 'Flux models', 'turn events like TurnInfo', and clearly names the API endpoint '/v2/listen'. Also distinguishes from related skills by naming specific alternatives.

Clearly answers both 'what' (calls Deepgram Conversational STT v2/Flux for turn-aware streaming transcription, covers specific methods and events) and 'when' (explicit 'Use when' clause at the start, plus explicit trigger terms and disambiguation guidance for when NOT to use it).

Excellent coverage of natural trigger terms explicitly listed: 'flux', 'v2 listen', 'conversational STT', 'turn detection', 'end of turn', 'EOT', 'listen.v2'. These are terms a developer would naturally use when working with this specific API.

Highly distinctive — explicitly disambiguates from two related skills ('deepgram-js-speech-to-text' for v1 ASR and 'deepgram-js-voice-agent' for full-duplex assistants), carving out a clear niche for v2/Flux conversational STT specifically.

Generally efficient but includes some unnecessary sections like the 'Central product skills' promo block and the 'When to use this product' section which, while useful, adds tokens for routing decisions Claude could handle from the YAML description. The gotchas and API reference sections are well-targeted though.

Provides fully executable, copy-paste-ready code for authentication and the main quick start flow. Key parameters, socket methods, and specific event types (TurnInfo, Connected, FatalError) are concretely named. The gotchas section gives specific, actionable guidance (e.g., 'use sendCloseStream not sendFinalize').

The quick start demonstrates a clear sequence: create connection → register handlers → connect → wait for open → stream audio → close stream. The event handling shows error recovery (FatalError → close). The gotchas reinforce correct ordering ('createConnection is lazy, call connect() after registering handlers'). For a WebSocket streaming skill, this is a well-sequenced workflow.

The API reference section provides a layered approach pointing to source files and external docs, which is good. However, there are no bundle files to support the references to source paths like 'src/CustomClient.ts' or 'src/api/resources/listen/resources/v2/client/Client.ts'. The skill also inlines content that could be split (gotchas, full parameter lists) but given no bundle exists, this is reasonable. The reference to a non-existent 'reference.md' that 'does not currently document listen.v2' is slightly confusing.
