Conciseness

The body assumes Claude's competence throughout — no basic-concept explanations — and every section carries repo-specific knowledge (availability table, gotchas, example files). Not 5 because the eight product-doc URLs and the 'Central product skills' install section could be trimmed or condensed without losing guidance value.

Actionability

Provides copy-paste-ready code for auth, the REST quick start with real parameter values, and the WSS subset call, plus named repo example files to start from. Not 4 because the concrete code covers the common REST and WSS cases completely with no missing execution details.

Workflow Clarity

Clear sequencing guides the decision path: when-to-use → REST vs WSS availability table → quick starts → gotchas, and the single action (turn flags on and call the API) is unambiguous. Not 5 because there is no validation guidance (e.g., confirming flags took effect in the response), and gotcha #1 says summarize is versioned ("v2") yet no snippet shows the actual versioned syntax.

Progressive Disclosure

A single-file skill with well-organized sections and a clearly signaled, layered, one-level-deep 'API reference' section; no bundle files exist, and nothing that belongs in a separate file is inlined. Not 5 because navigation leans on in-repo paths ("reference.md", "src/CustomClient.ts") that are not part of the skill bundle, and the inline URL list is somewhat heavy.

Specificity

Lists multiple concrete analytics features ("summarize, topics, intents, sentiment, diarize, redact, detect_language, and entity detection") plus the exact SDK surfaces for both REST ("client.listen.v1.media.transcribeUrl / transcribeFile") and WSS ("createConnection() / connect()"). Comprehensive coverage of concrete actions; not 4 because there are no meaningful gaps in the capability enumeration.

Completeness

Clearly answers both: what ("Deepgram audio analytics overlays on /v1/listen" with a full feature list and both transport paths) and when ("Use when writing or reviewing JavaScript/TypeScript in this repo that calls..." plus a concrete trigger list). Not 4 because both what and when are explicit with concrete trigger phrases, not merely present.

Trigger Term Quality

Explicit natural triggers ("audio intelligence", "summarize audio", "diarize", "sentiment from audio", "redact PII", "detect language audio") would naturally be said by users needing this skill. Not 5 because common synonyms like "speaker separation", "topic detection", "entity recognition", or "language identification" are absent.

Distinctiveness Conflict Risk

Occupies a clear niche (analytics on audio via /v1/listen) and explicitly redirects adjacent cases to sibling skills ("Use deepgram-js-speech-to-text for plain transcription and deepgram-js-text-intelligence for analytics on already-transcribed text"). Not 4 because the audio-vs-text and STT-vs-intelligence boundaries leave minimal overlap risk.
