Conciseness

The body is code-first and assumes Claude's competence — no padding explaining what TTS or WebSocket is, and comments in the examples earn their place (e.g. 'Log write failures rather than throwing from the WebSocket callback thread'). It falls short of 5 because the 'Central product skills' section is promotional padding and the five-source layered reference list could be tightened.

Actionability

Complete, copy-paste-ready Java for REST, WebSocket, and async paths with full imports and real class names ('SpeakV1Request.builder()...generate(request)', 'wsClient.sendFlush(SpeakV1Flush.builder().type(SpeakV1FlushType.FLUSH).build())'), plus a concrete gotchas section. The common cases are covered with executable code, matching the score-5 anchor.

Workflow Clarity

The two flows are unambiguously sequenced: a REST-vs-WebSocket decision section, and the WebSocket example registers handlers before 'connect().get(10, TimeUnit.SECONDS)' then sendText → sendFlush → sendClose, with 'Flush before close on WebSocket' restated in Gotchas. As a simple, non-destructive code-usage skill whose single actions are unambiguous, it earns 5 under the rubric's simple-skill note.

Progressive Disclosure

Sections are well organized and the 'API reference (layered)' pointers (in-repo source dirs, OpenAPI/AsyncAPI URLs) are one level deep and clearly signaled, with no nested-reference chains. It sits at 4 rather than 5 because the inline 'Key parameters / API surface' listing and the promotional 'Central product skills' section are organization gaps that a references/ bundle file could offload.

Specificity

The description names concrete actions with exact SDK call paths — 'one-shot REST via `client.speak().v1().audio().generate(...)` and streaming synthesis via `client.speak().v1().v1WebSocket()`' — covering both API surfaces comprehensively in third-person voice. It exceeds the score-4 anchor ('minor gaps in coverage') because both modes plus the boundary case are explicitly enumerated.

Completeness

It clearly answers both questions: 'Use when writing or reviewing Java code in this repo that calls Deepgram Text-to-Speech v1' gives the when, 'Covers one-shot REST ... and streaming synthesis' gives the what, and concrete trigger phrases are listed. This is an exact match for the score-5 anchor.

Trigger Term Quality

An explicit trigger list — 'tts', 'text to speech', 'speak', 'aura', 'streaming tts', and 'speak websocket' — covers natural synonyms users would say, including the model name. This matches the comprehensive-synonym anchor rather than score 4 ('a few natural terms missing').

Distinctiveness Conflict Risk

It is scoped to the Java SDK and TTS v1, and explicitly redirects the nearest overlapping skill: 'Use `deepgram-java-voice-agent` for full-duplex assistants instead of one-way synthesis.' This clear niche with minimal conflict risk matches the score-5 anchor.
