57%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 short, well-sectioned, and correctly delegates implementation detail to a real one-level-deep reference file, which is exemplary progressive disclosure. However, it opens with a known-concept explanation, duplicates its review instructions across two sections, and offers no executable commands or validation checkpoints in the body itself, leaving both actionability and workflow clarity at the middle anchor.
Suggestions
Drop or shrink the opening sentence explaining what E2E testing is — Claude already knows this — and merge the overlapping Check and Code Review sections into one.
Add a validation checkpoint to the workflow, e.g. after Fix: "Run the new E2E suite locally, then confirm the CI workflow fails when a test fails" — this directly serves the skill's stated focus on continuous verification.
Include one small inline example (e.g. a two-line Playwright data-testid selector) so the body is actionable without requiring a jump to references/rule.md for the most common case.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The opening sentence "E2E tests catch integration issues that unit tests miss—verifying your application works correctly from the user's perspective across all components" explains a concept Claude already knows, and the Check and Code Review sections substantially duplicate each other (both direct a review of E2E coverage/enforcement). Mostly efficient with some removable explanation and tightening fits anchor 3 rather than 4, where over-explanation would be merely minor. | 3 / 5 |
Actionability | The Quick Reference names concrete practices ("Use data-testid attributes", "Implement Page Object Model", "artifact uploads on failure") and Fix names Playwright/Cypress, but the body itself contains no commands or code — e.g. "Add E2E tests for critical user journeys using Playwright or Cypress" is a directive without the executable detail (which lives only in references/rule.md). Concrete-but-incomplete guidance with missing key execution details matches anchor 3, not 4's 'mostly executable with minor gaps'. | 3 / 5 |
Workflow Clarity | Check → Fix → Explain → Code Review provides a recognizable rough sequence, but there are no validation checkpoints: nothing tells the model to run the new suite, confirm it passes, or verify CI actually blocks regressions — the very thing the skill says to focus on. Steps listed with missing checkpoints fits anchor 3 rather than 4, which requires most checkpoints present. | 3 / 5 |
Progressive Disclosure | The body is a lean overview with clearly signaled one-level-deep navigation: "For full implementation details, code examples, and framework-specific guidance, see `references/rule.md`" — and that file exists and contains exactly the promised code examples and framework guidance. This is the anchor-5 pattern: appropriate split, easy navigation, no nesting. | 5 / 5 |
