Conciseness

The body is lean: every section (auth, connection setup, key parameters, gotchas, examples, references) adds information Claude would not infer, and no common concepts (what WebSocket is, how Go imports work) are explained. Matches the level-5 anchor 'every token earns its place'; the level-4 anchor's 'minor instances of over-explanation' cannot be identified.

Actionability

The connection-setup block is complete, copy-paste-ready Go with correct imports and exact package paths ("listen.NewWSUsingCallbackWithDefaults", "interfaces.FluxTranscriptionOptions"), followed by concrete parameter names, constructor variants, and real example file paths. Matches level-5 'fully executable; specific examples cover the common cases'.

Workflow Clarity

Clear sequence (set DEEPGRAM_API_KEY -> construct with defaults -> Connect -> Write/Stream audio) with explicit checkpoints in the code ("if err != nil { log.Fatal(err) }", "if !client.Connect() { log.Fatal(\"connect failed\") }"). Falls short of level 5 because there is no error-recovery guidance (e.g., what to do on connect failure or mid-session errors) and the audio-send/event-handling flow is only pointed at, not sequenced; still clearly above level 3 since the sequence and inline checks are present.

Progressive Disclosure

No bundle files ship with this skill, and the body is a genuine overview: a layered API-reference ladder (in-repo files -> OpenAPI -> AsyncAPI -> Context7 -> product docs) with one-level-deep, well-signaled references, plus pointers to runnable example files for the full flow. Navigation is easy and nothing that belongs in a separate file is inlined; matches the level-5 anchor.

Specificity

Quotes concrete specifics: "planning or reviewing Go SDK work for Deepgram conversational STT / Flux v2", "callback and channel Listen v2 WebSocket clients with typed options and mid-session configuration", plus explicit v1 routing. Coverage is comprehensive for the skill's niche with no vague filler; the level-4 anchor ('minor gaps in coverage') fits worse because every capability area (clients, options, mid-session config, routing) is named.

Completeness

Explicitly answers both: what ("ships first-class callback and channel Listen v2 WebSocket clients with typed options and mid-session configuration") and when ("Use when planning or reviewing Go SDK work for Deepgram conversational STT / Flux v2") with a concrete trigger phrase. This matches the level-5 anchor exactly; level 4 ('when could be more explicit') does not apply since the 'Use when' clause names specific triggers.

Trigger Term Quality

Natural terms present: "Go SDK", "Deepgram", "conversational STT", "Flux v2", "Listen v2", "WebSocket", "transcription". Good coverage but a few natural phrasings users would say are missing (e.g., "real-time", "streaming", "speech to text" spelled out); not the level-5 anchor's 'comprehensive coverage including synonyms and extensions', though 'STT'/'transcription' synonyms keep it clearly above level 3.

Distinctiveness Conflict Risk

Clear niche (Go SDK + Flux/conversational v2) with an explicit disambiguation: "Route v1 transcription to deepgram-go-speech-to-text." Minimal conflict risk with sibling Deepgram skills; matches the level-5 anchor's 'clear niche with distinct triggers'.
