Conciseness

The body is information-dense and operational, explaining only tool-specific facts Claude cannot know (limits, grants, request-ID semantics), but a few sentences are trimmable fluff ("works with Codex, Claude Code, Qoder, OpenClaw, Hermes, and compatible clients", "The skill is free software…") and some long legalistic sentences could be tightened. Not 3 because padding is minor; not 5 because those non-earning tokens are present.

Actionability

Fully executable throughout: copy-paste-ready CLI invocations (`node scripts/foleyix.mjs generate --mode narration --prompt "…" --out ./welcome.wav --json`), concrete limits (3,000-character input, 30 s/10 MB references, up to three `--voice-id` bindings, ten-minute wait), and mode/input tables cover the common cases.

Workflow Clarity

The workflow is clearly sequenced (choose workflow → prepare prompt → connect account → check quota → generate → verify/deliver) with explicit validation checkpoints: check quota before generating, verify status and absolute path before calling a task complete, listen and compare when playback is available, refuse auto-replacement of `unknown` tasks, and reuse the same request ID for retries.

Progressive Disclosure

Six well-signaled references ([references/prompt-writing.md], [references/sound-design.md], [references/speech.md], [references/cli.md], [references/capabilities.md], [references/audio-capabilities.json]) all exist and are one level deep, but the body carries more inline operational detail (voice-reference binding rules, quota arithmetic, request-ID recovery) than a lean overview, so organization is good rather than fully split.

Specificity

The description lists multiple concrete actions ("Write, optimize, or repair Foleyix prompts", "check tasks and quota, then download private WAV results") and comprehensively enumerates the audio domains (background music, songs with vocals and lyrics, podcasts, ambience, sound effects, game effects, narration, dialogue, sound scenes) with no coverage gaps.

Completeness

The "what" is explicit and concrete, but the "when" is only the sub-clause "when generation is requested", which conditions the download step rather than telling Claude when to invoke the skill; there is no "Use when…" or equivalent trigger guidance, capping this dimension at 3.

Trigger Term Quality

It covers the natural phrases users would say — "background music", "songs with vocals and lyrics", "podcasts", "ambience", "sound effects", "game effects", "narration", "dialogue", "sound scenes", and the file format "WAV" — comprehensively including synonyms and domain variations.

Distinctiveness Conflict Risk

The branded tool name (Foleyix) plus audio-specific outputs (WAV results, music, podcasts, sound effects) establish a clear niche with distinct triggers and minimal risk of firing for unrelated skills.
