88%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 strong, dense skill body: every step is executable with exact commands, viewports, and error-recovery paths, and the 7-step workflow is sequenced with real validation checkpoints (prerequisite checks, server verification, rate-limit honesty, attribution uncertainty). The only weaknesses are the redundant 'Lessons' section duplicating guidance already in steps 6-7 and an all-inline structure slightly beyond overview length.
Suggestions
Delete the 'Lessons' section (or fold it into steps 6-7): its three bullets restate guidance already given inline — 'measure spacing, don't eyeball it', data-driven text classification, and shared-component mismatches being a UX decision — so the recap costs tokens without adding new information.
Move the detailed design-comparison procedure (step 6's measurement workflow, Figma-to-USWDS unit mapping, and text-difference classification rules) into a references/ file (e.g. references/design-comparison.md) and keep a two-line pointer in the workflow, keeping SKILL.md a lean overview.
Tighten step 1's Figma-link collection into a compact table or single grep instruction; the ordered three-source list with per-source conditionals can be compressed without losing the search order.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Nearly every line carries non-obvious project knowledge Claude cannot infer (routes are JSX attributes not object-literal 'path:', Playwright MCP rejects absolute paths outside allowed roots, Figma seat rate limits, ticket-less branch conventions, USWDS 8px spacing units). The one inefficiency is the 'Lessons' section, which restates three points already embedded verbatim in steps 6-7 (measure don't eyeball, classify data-driven text by format, shared component = UX decision). Efficient with minor over-explanation that could be trimmed, fitting the 4 anchor; not 5 because of that genuine redundancy, and not 3 because the prose is otherwise tight with no filler or explanation of concepts Claude already knows. | 4 / 5 |
Actionability | Copy-paste-ready commands throughout: 'git fetch origin main && git diff --name-only origin/main...HEAD -- frontend/src', 'curl -s -o /dev/null -w "%{http_code}" http://localhost:3000', 'mktemp -d /tmp/playwright-mcp/visual-check.XXXX', a concrete grep regex for Figma URLs, and 'grep -n 'path="' frontend/src/index.jsx'. Exact viewport sizes (1280x800, 375x812), a numeric tolerance (+-2px), specific MCP tool names per step, and named sign-in users fully cover the common cases. | 5 / 5 |
Workflow Clarity | A clearly sequenced 7-step workflow (presented as a checklist then elaborated) with explicit validation checkpoints and feedback loops: check MCP availability before starting and stop if Playwright MCP is missing; verify the server responds before capturing ('curl -s -o /dev/null -w "%{http_code}"'); 'browser_wait_for' the main content rather than fixed sleeps; handle rate-limit errors by reporting them 'rather than reporting "no differences found"'; ask before exceeding ~6 targets; and mark attribution as uncertain when no baseline was run. Error recovery is addressed at every fragile point. | 5 / 5 |
Progressive Disclosure | Well-organized single file: Prerequisites, Inputs, a workflow overview checklist, numbered step elaborations, and clearly separated optional Before/after and Lessons sections — no bundle files exist (no references/, scripts/, or assets/), so nothing is misfiled. However at ~80 lines everything is inline, and some content (the step-6 measurement procedure and the Lessons recap) could live in a one-level-deep reference file to keep SKILL.md a leaner overview. Anchor 4 ('good structure; most content appropriately placed; minor organization gaps') fits better than 5, which expects well-signaled external references or a sub-50-line skill with none needed. | 4 / 5 |
