Conciseness

The body is dense operational prose with almost no explanation of concepts Claude already knows — every step carries commands, gates, or routing rules rather than background. It is not a 5 because of verifiable duplication ("You are the orchestrator. Run each step... pass each gate before continuing" appears in both the front-door paragraph and the following paragraph) and several long, comma-chained sentences that could be tightened without losing meaning.

Actionability

Every step gives copy-paste-ready commands with full flag sets (`npx hyperframes init "videos/<project>" --non-interactive --example=blank --skill=faceless-explainer`, `node <SKILL_DIR>/scripts/audio.mjs sync-durations --audio-meta ./audio_meta.json --storyboard ./STORYBOARD.md`), concrete file formats for `tokens.json`, explicit error policy ("surface stderr and stop — don't pile on recovery commands... cheapest safe edit... then rerun the failed check"), and a documented false-positive with an exact selector. It does not earn below 5: placeholders like `<project>` and `<voice-id>` are appropriately parameterized, and deferring field lists to format references is correct structure, not a gap.

Workflow Clarity

Steps 0–6 are explicitly sequenced with a per-step Goal and a bolded **Gate** (explicit validation checkpoints: "`build-frame.mjs` exited 0 — `frame.md` exists from a named preset", "`lint` and `check` passed and the snapshots were inspected before render"), an error-recovery feedback loop in Step 6, an audio-async dependency handled in Step 5 ("Wait for Step 3.1 audio to finish if audio was started"), and explicit collaborative/autonomous branches at each user-gated step. This matches the top anchor — clear sequence, explicit validation, feedback loops — with nothing missing.

Progressive Disclosure

Structure is good: the body stays an orchestrating overview, all four local `references/*.md` files cited in the body exist, all cited local `scripts/*.mjs` exist, and the Quick Reference table maps each file to when to read it with one-level-deep references. It is not a 5 because `sub-agents/frame-worker.md` is cited twice (Step 5: "this skill's `sub-agents/frame-worker.md`" as half of the worker role payload, and again in the Quick Reference table) but no `sub-agents/` directory exists in the bundle — a broken local reference the Step 5 dispatch depends on. This is a minor organization gap against an otherwise well-signaled structure, so 4 rather than 3.

Specificity

"Turn arbitrary text — an article, notes, a topic, a brief — into a faceless explainer video" names the core action with enumerated inputs, and "the visuals are invented per scene (typography, abstract graphics, diagrams, data-viz)" enumerates four concrete output forms. Not 5: the description never surfaces the pipeline actions the skill actually performs (design-system selection, storyboard/script drafting, narration/audio, render to MP4), so coverage of what it concretely does has a gap. Not 3: far more than 1–2 bare actions — inputs, visual modes, and a negative boundary are all concrete.

Completeness

What is explicit ("Turn arbitrary text... into a faceless explainer video... visuals are invented per scene") and when is explicit with concrete trigger phrases ("Use for topic explainers, concept breakdowns, how-tos, listicles"), matching the top anchor's what+when-with-triggers pattern. Not 4: the when-clause is not merely present but enumerates four concrete use cases and is reinforced by a negative trigger ("Not a video built from a website") and a routing rule ("Unclear → /hyperframes").

Trigger Term Quality

"Use for topic explainers, concept breakdowns, how-tos, listicles" plus "faceless explainer video" in the what-clause covers the natural phrasings a user would say for this need. Not 5: common variants like "tutorial video", "educational video", or "video from an article/notes" are absent, so a few natural trigger phrases are missing. Not 3: synonyms are covered across four distinct use-case nouns plus the explainer-video framing, well beyond a single generic keyword.

Distinctiveness Conflict Risk

The description carves a clear niche (text-in, invented-visuals explainer) and actively prevents mis-triggering: "Not a video built from a website (/product-launch-video — promo or tour)" disambiguates the nearest sibling, and "Unclear → /hyperframes" routes ambiguous requests away. Minimal conflict risk, matching the top anchor's clear-niche-with-distinct-triggers pattern; not 4 because it exceeds minor-distinctness with an explicit exclusion plus a fallback route.
