Lists multiple specific concrete actions: createConnection/connect, sendSettings, sendMedia, runtime updates, event handling, function-call responses. Also names the specific API endpoint and distinguishes from related skills with concrete alternatives.

Clearly answers 'what' (building interactive voice agents via the converse API with specific operations) and 'when' (explicit 'Use when' clause at the start, plus explicit trigger terms at the end, plus negative guidance on when to use other skills instead).

Explicitly lists natural trigger terms ('voice agent', 'agent converse', 'full duplex', 'barge-in', 'function calling', 'agent.v1') and includes technical identifiers users would reference like the API path and method names. Good coverage of both natural and technical terms.

Exceptionally distinctive — explicitly delineates boundaries against four other related skills (text-to-speech, speech-to-text, conversational STT, management API), making it very unlikely to conflict with similar Deepgram skills.

Generally efficient but includes some unnecessary explanation (e.g., 'When to use this product' section explains concepts Claude can infer, the 'Central product skills' section at the end is tangential, and some prose like 'The websocket itself is routed to the agent host by src/CustomClient.ts' adds marginal value). The gotchas section is valuable but could be tighter.

Provides fully executable, copy-paste-ready code for authentication, connection setup, and settings configuration. The quick start example is complete with real method calls, event handling, and concrete parameter values. Function call response format and runtime update methods are specifically named.

The implicit workflow (create connection → connect → waitForOpen → sendSettings → handle events → send media) is discernible from the quick start code but is never explicitly sequenced as numbered steps with validation checkpoints. Gotcha #1 hints at ordering but there's no explicit 'if settings fail, do X' feedback loop. For a WebSocket-based multi-step process, explicit validation/error recovery steps are missing.

References to external docs, OpenAPI/AsyncAPI specs, and example files are well-signaled. However, no bundle files are provided, so references to 'reference.md' and source files like 'src/CustomClient.ts' cannot be verified. The API reference section lists 5 layers of references which is good navigation, but the skill itself is somewhat long with inline content (gotchas, limitations, key parameters) that could potentially be split out.
