81%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-engineered, phase-gated workflow with explicit validation checkpoints, a mandatory preflight gate, and disciplined on-demand loading — the process design is about as clear as the rubric's top anchor. The deductions are localized: duplicated analyser-sizing rationale costs conciseness, the core script/crop commands live in delegated files that are absent from the provided bundle, and that same absence leaves the otherwise excellent reference structure unverifiable.
Suggestions
State the analyser-optimised sizing rationale (768 px, ~786 tokens/frame, 0.5 s GOP) once — either in the Phase 1 input table or the Phase 4 paragraph — and link to `rules/cropping.md#analyser-optimised-sizing` for the numbers instead of repeating them.
Inline a minimal runnable `record.mjs` skeleton (launch, context with recordVideo, one interaction, context.close, print VIDEO=path) and the exact ffmpeg crop command, so the core path is executable before loading the template and rules files.
The linked bundle files (`rules/*.md`, `templates/record.mjs.template`) are missing from the skill directory — ship them with the skill (or fix the paths) so the 'Required Reading by Phase' table's references resolve.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and assumes competence (tables, one-line anti-patterns, hard rules), but the video-analyser sizing rationale is stated twice — "768 px is the ... Pareto knee — UI text stays legible, image tokens stay cheap (~786 tokens/frame on Sonnet)" in the Phase 1 table and again the "Net effect: 768 px wide ... ~786 image tokens/frame ... short GOP" paragraph in Phase 4 — and the caller-override/GOP reasoning repeats detail already delegated to `rules/cropping.md`. This is anchor 4 ('efficient; minor instances of over-explanation that could be trimmed') rather than anchor 5, whose 'every token earns its place' is violated by the duplicated rationale. | 4 / 5 |
Actionability | Mostly executable: the preflight checks, `node .agent/recordings/<slug>/record.mjs` run command, exact API constraints (`chromium.launch({ headless: true })`, `recordVideo: { dir, size: viewport }` on the context, `await context.close()` before reading the path), and the delivery-summary template are all concrete and runnable. However the two core generative artifacts — the recording script's contents (delegated to `templates/record.mjs.template`) and the ffmpeg crop command (delegated to `rules/cropping.md`) — are not present, so the common case cannot be executed from the body alone; this fits anchor 4's 'concrete code or commands with minor gaps' rather than anchor 5's copy-paste-ready coverage. | 4 / 5 |
Workflow Clarity | The phase pipeline (0 preflight gate → 1 inputs → 2 script generation → 3 run → 4 crop → 5 deliver → 6 integration) is explicitly sequenced with validation throughout: a mandatory preflight decision table that halts on missing tools, "On non-zero exit, do not crop — surface the error and stop", resolving the output via the script's printed `VIDEO=<path>`, and a Definition of Done checklist verifying exit code, file size, bbox.json, and delivery. This matches anchor 5 (explicit validation steps, error-recovery direction, checklist) and exceeds anchor 4, which tolerates missing checkpoints — none are missing here, and the operation is neither destructive nor batch, so no cap applies. | 5 / 5 |
Progressive Disclosure | Structure is textbook: the body declares itself a thin index, every detail file is one level deep with per-context links, and a 'Required Reading by Phase' table maps exactly which files to load per phase with 'load on demand — do not preload'. The gap is that the referenced bundle files (`rules/preflight.md`, `rules/cropping.md`, `templates/record.mjs.template`, etc.) are not present alongside SKILL.md in this bundle, so the links cannot be verified to resolve; anchor 4's 'references mostly clear; minor organization gaps' fits, while anchor 5 would require the split to be verifiably complete. | 4 / 5 |
