Use when building or reviewing a client-side React SPA bundled by Vite (React 19.2): components, where state lives, hooks, server data fetching, client routing, re-render and effect bugs. NOT App Router / server components / SSR (that is `nextjs`); NOT native screens (that is `react-native`).
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
# React + Vite SPA — Components, State, Data Fetching (React 19.2, 2026) **Hand-off — picking dependencies.** Which library to reach for (UI primitives, command menus, toasts, OTP inputs, charts, virtualization, drag and drop, state, styling, theming) is `../ui-engineering/SKILL.md`'s — build vs adopt is decided there, before hand-rolling a component. Animating what you install is `../motion-craft/SKILL.md`'s. > Build or review a fast, typed, correctly-architected **client-side** React single-page app bundled by Vite. No server runtime, no RSC tree, no framework router. Server-rendered React (App Router, server actions, SSR/SSG) is not this skill — that is `../nextjs/SKILL.md`. **SDD gate — before writing feature code.** If this skill fired on a **new, non-trivial feature or behaviour change** and there is **no approved spec + plan** under `02-DOCS/wiki/sdd/`, stop and hand off to `../specify/SKILL.md`: it runs brainstorm → spec → plan → tasks, then routes back here once the plan is approved. Build directly only for a genuinely one-line / low-risk change. Method: `../sdd/SKILL.md`. ## First: confirm it's a Vite SPA, not a framework …

How to install
mdr add ericrisco/rsc-harness/react@sha256:12f4dea85784f8ebThe line at the top of this page pins the label git:20260901.09d08c9, 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.
