56%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.
The body is highly actionable — concrete, idiomatic code across components, hooks, state, forms, routing, and testing — and the test-first workflow is clearly sequenced with real validation checkpoints. However, it is noticeably bloated by a near-verbatim duplicated testing section and restated React basics, and it is a monolith with no reference files despite pointing to several external skills that don't exist in the bundle.
Suggestions
Deduplicate the testing guidance: the "Testing" section repeats the Button/useCounter test examples from "Test-First Development" almost verbatim — keep one canonical set (or a reference file) and cut the other.
Split extended test templates, pattern library, and anti-patterns into references/ files (e.g., references/testing.md, references/patterns.md) and link them from a leaner SKILL.md overview.
Trim explanations of concepts Claude already knows (memoization, code splitting, basic router setup) to bare pattern snippets, and either give the demo-video/visual-validation default concrete steps and commands or remove the dangling references to non-existent skills.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The ~570-line body duplicates the Button and useCounter test examples almost verbatim in both the "Test-First Development" and "Testing" sections, inlines ~140 lines of test templates, and restates basics Claude already knows (memoization, lazy routes, router setup). Not a 3 because the wholesale duplicated section is more than minor padding that "could be tightened". | 2 / 5 |
Actionability | Concrete, mostly copy-paste-ready TypeScript and Playwright examples cover the common cases (component, hook, Zustand store, React Query hooks, RHF+Zod form, protected route, E2E spec). Not a 5 because a few snippets are not executable as written — the first Button uses `styles[variant]` with no import, and the CSS-modules example drops loose JSX into a CSS code block. | 4 / 5 |
Workflow Clarity | The TFD workflow is explicitly sequenced with validation checkpoints ("Run test (it fails) → Confirms test is valid"), a pre-implementation checklist, and an enforcement template. Not a 5 because the skill's stated default visual-validation/demo-video done-requirement is described with no steps, commands, or checkpoints, leaving a validation gap in the completion workflow. | 4 / 5 |
Progressive Disclosure | Section headers make the document navigable, but no bundle files exist at all: test templates, pattern library, and anti-patterns that belong in reference files are inlined in a ~570-line monolith, and pointers to "demo-video", "visual-validation", "playwright-testing", and "base" resolve to nothing in the bundle. Not a 4 because the unsplit inline bulk and dangling references are more than minor organization gaps. | 3 / 5 |
