Conciseness

The body is mostly efficient — no concept explanations Claude already knows, and every section carries real constraints — but there is noticeable redundancy that could be tightened: "Deterministic, FREE (PIL + FFmpeg), no paid calls" and "never a paid call per segment" each appear twice (intro/Run vs. Contract), and the real-logo end-card requirements ("base64-decoded", "never typeset", "never freeze") are stated in full in both "The FREE assembly" and "Contract". This fits the anchor for mostly efficient with some unnecessary repetition, rather than the noticeably-verbose anchor below it, since nothing is concept-level padding.

Actionability

The body names concrete config keys ("config.brand_voice", "music.bpm", "beat_structure.concat_order", "config.text_cards", "config.end_card"), exact parameters (1080×1920, ~6° skew, 1.08× echo, ±1% scale + ±3px drift, 192 kbps), and one genuinely executable FFmpeg directive ("-map 0:v -map 1:a"). But the "Run" block contains only comments — no runnable command — and the actual PIL implementations live in an external "Soundboks reference" that is "copied + adapted per run, not vendored" and absent from the bundle. This matches the anchor for some concrete guidance with pseudocode instead of executable code and missing key details; it is not the minimal-high-level-hints anchor (2) because the parameter and config-field specificity is high, and not anchor 4 because nothing in the body can actually be executed.

Workflow Clarity

The five phases are clearly sequenced ("Phase 0 assets → Phase 1 PAID Seedance + music (parallel, gated) → Phase 2 FREE PIL cards → Phase 3 FREE dice/intercut/concat/mux → Phase 4 watch/QC") with a documented config-field → step map in PIPELINE.md, and validation checkpoints exist (the ffprobe ≈192 kbps check against the silent ~1 kbps garbage-audio failure mode, plus the Phase 4 watch/QC gate). It falls short of anchor 5 because the error-recovery loop is only implied (no "if ffprobe shows garbage audio, re-mux with explicit maps"-style feedback step) and the phase sequencing in the body is prose, not a numbered, checkpointed list.

Progressive Disclosure

Scored against the actual bundle: all three referenced files exist (scripts/PIPELINE.md, scripts/README.md, scripts/config.example.json), each is announced with a clear one-line scope (config → structure to copy; PIPELINE.md → full field → step map with beat variants; README.md → the FREE assembly), and references are one level deep. The SKILL.md body is a genuine overview with details pushed to the bundle. It misses anchor 5 on navigation precision — files are referenced by bare name without the scripts/ prefix ("PIPELINE.md" rather than scripts/PIPELINE.md), and "README.md — documents the FREE assembly (below)" is ambiguous about location — leaving minor organization gaps that fit anchor 4.

Specificity

The description lists multiple concrete actions with full coverage of the assembly: "dice ONE Seedance 2.0 hypermotion clip into 5-6 segments", "intercut them with PIL kinetic-typography spec/CTA cards (italic skew, 1.08x outline echo, 3D extrusion, slam-with-shake, inversion flash)", "center-crop 1:1 to 9:16", "explicit-map mux a music bed", plus a base64-decoded real-logo end card. This matches the anchor for multiple specific concrete actions with comprehensive coverage; nothing in the assembly pipeline is left unnamed.

Completeness

The "what" is explicit and detailed (dice, intercut, crop, mux) and a "Use for..." clause is present: "Use for the product-hypermotion format." That satisfies both parts, but the trigger is self-referential — it names the format the skill itself defines rather than concrete situations a user would be in, so it does not reach the anchor for clearly answering "when" with concrete trigger phrases.

Trigger Term Quality

Relevant domain keywords exist ("hypermotion clip", "spec/CTA cards", "end card", "music bed", "9:16", "Seedance 2.0", "PIL", "FFmpeg") but they are almost entirely proprietary pipeline jargon — the natural phrases a user would say ("product ad video", "sizzle", "vertical video", "product showcase") are missing. This lands on the anchor for some relevant keywords but missing common variations or synonyms, not above it, since only someone already fluent in this exact format would utter these terms.

Distinctiveness Conflict Risk

"product-hypermotion" is a uniquely named format with distinct triggers, and the description explicitly fences off adjacent skills ("The paid steps (the ONE Seedance i2v, the music) are separate capabilities"), minimizing the chance it fires for the paid-generation or music skills. Minimal conflict risk — a clear niche.
