Conciseness

The body is lean and operational — no padding, no explanations of concepts Claude already knows, and every section earns its tokens. It falls short of the level-5 anchor because of unpinned-down time-sensitive details: the 'heygen >= v0.1.6' version requirement and install/version instructions sit in the main flow rather than a deprecated/old-patterns section, which the guidelines say should penalize conciseness.

Actionability

Every command is copy-paste ready: the exact resolve invocation with flags, worked examples for all four types with real output lines ('resolved bgm_001 → .media/audio/bgm/bgm_001.mp3 (bgm, 25s)'), an adopt example, the flags table, and install/auth commands. Specific examples cover the common cases, matching the level-5 anchor.

Workflow Clarity

The 'How it works' section gives a clear 5-step cascade and the missing-CLI failure path is described, but there are no validation or verification checkpoints anywhere — nothing confirming the frozen file exists/probes correctly, and no verify step after the batch `--adopt` import. Per the guidelines, batch operations without validation cap workflow_clarity at 3, and this cap applies despite the otherwise clean sequence.

Progressive Disclosure

The body is a well-organized overview with clearly signaled sections, and the referenced bundle path (`<SKILL_DIR>/scripts/resolve.mjs`) is a real file exactly one level deep, keeping search noise in scripts as designed. Minor gaps keep it at level 4 rather than 5: the ~120-line body inlines some material (install/version instructions, the index sample) that could live in a reference file, and the `scripts/lib/` modules and tests are present in the bundle but undocumented.

Specificity

The description lists multiple concrete actions covering the full cascade: 'project cache, global cache, HeyGen catalog search, freeze, register', plus the outcome 'frozen local file + ledger record'. Coverage of the skill's scope is comprehensive, matching the level-5 anchor; only the 'Agent Media OS' branding is mildly fluffy.

Completeness

Both parts are explicit: the 'what' ('resolve any media need (BGM, SFX, image, icon) into a frozen local file + ledger record... handles the full cascade') and the 'when' ('Use when a composition needs background music, sound effects, images, or icons'). This matches the level-5 anchor of clearly and explicitly answering both with concrete trigger phrases, and not the level-4 anchor where the 'when' could be more specific.

Trigger Term Quality

Natural trigger phrases are present — 'background music, sound effects, images, or icons' plus BGM/SFX — which users would genuinely say. A few natural synonyms are missing (e.g., 'photos', 'logos', 'music track', file extensions), fitting the level-4 'good keyword coverage; a few natural terms missing' anchor rather than the comprehensive level-5 anchor.

Distinctiveness Conflict Risk

The niche is distinct — resolving/licensing external media assets via a specific cascade with a dedicated ledger — and unlikely to trigger for unrelated skills. Minor overlap risk remains with generic image/design or audio-generation skills triggered by 'images' or 'icons', placing it at the level-4 'mostly distinct; minor overlap risk' anchor rather than the minimal-conflict level-5 anchor.
