Quality

Content

73%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, information-dense skill body with a clear phased workflow, explicit quality gates, and excellent reference navigation. Its main weaknesses are noticeable cross-section redundancy of the same thresholds and the absence of any actual Playwright code examples in the body itself.

Suggestions

De-duplicate the 120s cap, VMAF/PSNR/SSIM thresholds, LUFS targets, and WCAG clauses — state each once in Core Contract or Critical Constraints and reference it from Always/Never instead of restating.

Add at least one minimal copy-paste Playwright page.screencast recording example in the Shoot phase so the core task is actionable without opening reference/implementation-patterns.md.

Trim the inlined Critical Constraints section to a concise summary and keep the full per-row detail in reference/playwright-config.md to reduce redundancy with the Reference Map targets.

DimensionReasoningScore

Conciseness

The body is information-dense and avoids explaining concepts Claude already knows, but the same constraints recur across Core Contract, Critical Constraints, Always, and Never (the 120s cap, VMAF/PSNR/SSIM thresholds, LUFS targets, and WCAG clauses each appear 3–4 times), which is redundant padding that could be tightened.

3 / 5

Actionability

Provides concrete, executable configuration guidance throughout (specific Chrome flags, ffmpeg-quality-metrics commands, LUFS/viewport/codec values, API names like page.screencast), but includes no actual Playwright recording code examples — the core demo-writing code is deferred to reference files.

4 / 5

Workflow Clarity

A clear Script → Stage → Shoot → Deliver sequence is laid out in a table with per-phase goals and key rules, an explicit Deliver-phase quality gate (VMAF/PSNR/SSIM verdict decides ship/reshoot), a reshoot feedback loop, and a referenced checklist.

5 / 5

Progressive Disclosure

Strong structure: a Reference Map table, per-recipe 'Read First' columns, and routing rules signal one-level-deep references with easy navigation, but the inlined Critical Constraints section duplicates content said to live in reference files, a minor organization gap. No bundle files were present to verify referenced paths against.

Description

87%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A concise, third-person description that clearly states both what the skill does and when to use it, with a distinct niche and concrete trigger phrases. It could add a few more natural synonyms (screencast, walkthrough, tutorial) and slightly more concrete action verbs to push specificity and trigger coverage higher.

DimensionReasoningScore

Specificity

Names the domain ('feature demo videos via Playwright E2E tests') and lists several specific capability areas ('scenario design, recording config, implementation patterns, quality checklists'), but these are capability categories rather than fully concrete verbs, leaving minor gaps versus a comprehensive action list.

4 / 5

Completeness

Explicitly answers both 'what' (producing automated feature demo videos via Playwright E2E tests with named capability areas) and 'when' via a concrete 'Use for product demos or onboarding material' trigger clause, matching the anchor-5 what-and-when structure.

5 / 5

Trigger Term Quality

Includes natural terms a user would say ('feature demo videos', 'product demos', 'onboarding material') with good coverage, but misses common synonyms like screencast, walkthrough, tutorial, or getting-started, and 'Playwright E2E tests' leans technical.

4 / 5

Distinctiveness Conflict Risk

Carves a clear niche — automated demo video production via Playwright E2E tests — with distinct triggers and minimal overlap risk versus generic video, E2E-testing, or doc skills.
