93%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.
An exemplary reference-style skill body: token-efficient, assumes competence, and packed with executable commands, exact config values, and hard-won gotchas (parallel-worker state leaks, forbidOnly in CI). The only structural limitation is that, as a topic reference rather than a workflow, it has no explicit step sequence with validation checkpoints — appropriate for this skill type.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and dense: every line carries non-obvious information (locator priority chain, CI-specific config values like "retries: 2 and workers: 1 in CI trade wall-clock for determinism") and assumes Playwright competence. No padded explanation of what E2E testing is — matches the anchor 5 'every token earns its place' example. | 5 / 5 |
Actionability | The commands block is copy-paste ready ("npx playwright test --ui", "npx playwright codegen http://localhost:3000"), config guidance uses exact values, and the mock pattern is real code ("await page.route('/api/login', route => route.fulfill({ status: 200, body: ... }))"). The single ellipsis is trivial; this fits anchor 5's fully-executable coverage of common cases. | 5 / 5 |
Workflow Clarity | This is a patterns/reference skill rather than a sequential process, so there is no multi-step workflow to sequence; verification guidance is present but implicit ("show-report # HTML report (verify 0 failures)", "--debug # step through", attaching trace IDs to failure tickets). Fits anchor 4's 'clear with most checkpoints' better than 5's explicit validate-fix-retry loops, which this format doesn't need given no destructive/batch operations. | 4 / 5 |
Progressive Disclosure | Under 50 lines with no bundle files, organized into clean sections (Layout, Locator priority, Gotchas, Commands), and the only pointers are one level deep and clearly signaled (project config at .opencastle/stack/testing-config.md and the official docs URL). Per the rubric's simple-skill guideline, this scores 5 with just well-organized sections. | 5 / 5 |
