81%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.
High-quality content: a clearly sequenced six-step workflow with executable, gotcha-aware Playwright code, an anti-patterns recovery table, and well-signaled external references. The main deductions are repeated citation filler, the https://localhost:3000 scheme bug, and an entirely single-file layout with no progressive split.
Suggestions
Trim the repeated "Per the [INP web.dev article]" filler sentences (it appears five times, including as a standalone line after Step 1) and cite once where each fact is non-obvious.
Change "https://localhost:3000" to "http://localhost:3000" in both Playwright tests so they run copy-paste against a typical dev server.
Move the CrUX query details and LoAF discussion into a references/ file (e.g. FIELD-DATA.md) linked from a short section, aligning Step 4's single-sample Math.max assertion with the anti-pattern guidance to run N iterations and assert P75.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and code-forward with only minor trimmable padding: "Per the [INP web.dev article]" is repeated as a standalone filler sentence (e.g. directly after Step 1) and the opening quoted INP definition restates what Claude largely knows. Fits anchor 4 (minor over-explanation) rather than 5 (every token earning its place). | 4 / 5 |
Actionability | Guidance is nearly fully executable — complete Playwright tests with real gotcha handling (visibilityState redefine-before-dispatch, buffered longtask observer, guarded LoAF) and a runnable CrUX curl. Both tests target "https://localhost:3000", which fails against a typical plain-HTTP dev server, a minor executable gap that keeps it at anchor 4 rather than 5. | 4 / 5 |
Workflow Clarity | Steps 1–6 are clearly sequenced (install → lab measure → decompose → CI assert → find blockers → field correlate), each Playwright step embeds an explicit validation assertion, and the Anti-patterns table plus "Lab passing + field failing = sample population mismatch" provide failure-mode → fix recovery guidance. No destructive or batch operations apply a cap. | 5 / 5 |
Progressive Disclosure | Sections are well organized and a References section clearly signals five one-level-deep external sources with what each provides, but there is no bundle split at all — everything is inline in a ~200-line file (the under-50-line exception doesn't apply), and detail like the CrUX/LoAF material could live in a reference file. Anchor 4 fits best. | 4 / 5 |
