78%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 well-structured, token-efficient review skill: the body gives an actionable blocker checklist with exact API names and cleanly defers depth to a real, one-level-deep reference file. The main weaknesses are slight redundancy between the Check and Code Review sections and the absence of any inline executable example or re-verification loop.
Suggestions
Merge the overlapping Check and Code Review sections (both instruct reviewing the route for blockers) into a single section that lists the concrete detection targets, cutting duplicated instruction without losing information.
Add one short inline snippet for the core pattern (e.g., the pagehide handler replacing unload, and refreshing state when pageshow.persisted === true) so the body is executable without opening references/rule.md.
Close the workflow with an explicit feedback loop: after fixing blockers, re-verify bfcache eligibility in DevTools to confirm the restore works.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and mostly earns its tokens — the Quick Reference bullets and Check/Fix sections name exact APIs (`unload`, `pagehide`, `pageshow.persisted`) without padding. Minor trimmable redundancy: the Check and Code Review sections overlap ('Review this route for back/forward cache blockers' vs 'Review route code, global listeners... related to Optimize pages for back/forward cache'), and the one-sentence bfcache intro re-explains a concept Claude already knows. | 4 / 5 |
Actionability | Guidance is concrete and specific — 'Never add an `unload` listener', 'Refresh time-sensitive state when `pageshow.persisted` is `true`', 'Keep `beforeunload` conditional' — with exact event names and properties. It falls short of 5 because the body contains no executable code or commands (the pattern snippets live only in references/rule.md), and the Explain section ('Explain how the back/forward cache differs from HTTP caching') is direction without a concrete checklist. | 4 / 5 |
Workflow Clarity | The Check → Fix → Explain sequence is clear and the Quick Reference acts as a checklist, with a verification step present ('Verify eligibility in DevTools instead of assuming a page is cacheable') and the Check section enumerating concrete detection targets. Not 5 because the checkpoints are spread across sections rather than sequenced, and there is no explicit feedback loop (detect blocker → fix → re-verify eligibility). | 4 / 5 |
Progressive Disclosure | The body is a concise overview that defers implementation detail to a single clearly signaled reference — 'For full implementation details, code examples, and framework-specific guidance, see `references/rule.md`' — and that file exists (113 lines) with no nested references, so navigation is one level deep and easy. The trailing rule-page URL is a minor, non-harmful duplicate of frontmatter metadata. | 5 / 5 |
