Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> Surface router: `/uiux`. You are here: `enhance-web-instant-nav`. # enhance-web-instant-nav — Instant Navigations **Degree of freedom: MIXED.** Which pages to speculate `[HIGH freedom]`; the exclusion list, `Sec-Purpose` handling, and re-measure `[LOW freedom — run exactly]`. > Applies to MPAs and Next.js App Router (server-rendered routes). Pure SPA > routing → use the framework's prefetch API; Speculation Rules are per-document. ## How to reason 1. **Observe** — quote 2nd-page LCP p75, bfcache test result, and the top 5 next-click paths 2. **Rank** — probability × page cost. Prefetch broadly; prerender only ≥ ~50% likely next pages 3. **Guard** — list every URL with GET side effects or per-user state; exclude or downgrade to prefetch 4. **Ship** — rules + server guard + analytics guard in the same PR 5. **Re-measure** — if 2nd-page LCP didn't drop, the rule isn't firing (DevTools → Application → Speculative loads) ## Worked example > **Observe:** blog; first-page LCP 1.9 s, next-article LCP 2.8 s; back button reloads (`unload` in analytics). > **Rank:** "next article" 61% of sessions → prerender moderate; category links → prefetch moderate. …

How to install
mdr add kensaurus/skills/enhance-web-instant-nav@sha256:d24894f126cc0299The line at the top of this page pins the label git:20260923.938ff43, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
