+# Using Vite+, the Unified Toolchain for the Web
+
+This project is using Vite+, a unified toolchain built on top of Vite, Rolldown, Vitest, tsdown, Oxlint, Oxfmt, and Vite Task. Vite+ wraps runtime management, package management, and frontend tooling in a single global CLI called `vp`. Vite+ is distinct from Vite, and it invokes Vite through `vp dev` and `vp build`. Run `vp help` to print a list of commands and `vp <command> --help` for information about a specific command.
+
+Docs are local at `node_modules/vite-plus/docs` or online at https://viteplus.dev/guide/.
+
+## Built-in Commands vs Scripts
+
+`vp <name>` runs a built-in command. `vp run <name>` runs a `package.json` script or a `vite.config.ts` task. Scripts cannot overwrite built-ins, so `vp dev` and `vp run dev` may do different things. Check `package.json` and `vite.config.ts` first, and run `vp run <name>` when the project defines a script or task with that name.
+
+## Tool Versions
+
+Run `vp toolchain` to show versions and relationships in the active Vite+
+release. Add a tool name to select part of the graph. For example, run
+`vp toolchain vite`. Use `--global` to ignore the local `vite-plus` package. Use
+`vp why <package>` to show the package-manager dependency graph.
+
+## Review Checklist
+
+- [ ] Run `vp install` after pulling remote changes and before getting started.
+- [ ] Run `vp check` and `vp test` to format, lint, type check and test changes.
+- [ ] Check if there are `vite.config.ts` tasks or `package.json` scripts necessary for validation, run via `vp run <script>`.
+- [ ] If setup, runtime, or package-manager behavior looks wrong, run `vp env doctor` and include its output when asking for help.

 ## Commands
 
-Run from project root. Prefer these `pnpm` scripts. `vp` subcommands (`vp test`, `vp lint`, `vp fmt`, `vp check`) are fine to run directly, since `vp` resolves the project's pinned Vite+ and its config; use `pnpm exec vp` if the global CLI isn't installed. `vp check` runs format, lint, and type checks. Never invoke `tsc`, `tsgo`, `vitest`, `oxlint`, or `oxfmt` directly or via `pnpx`, because bare tools use the wrong version and miss project context.
+Run from the project root. Bare `tsc`, `tsgo`, `vitest`, `oxlint`, and `oxfmt` use the wrong version and miss project context, so always go through `vp`, never through those tools directly or via `pnpx`. Without the global `vp` CLI, prefix each command with `pnpm exec`. The `pnpm` scripts in `package.json` are aliases for humans.
 
-- `pnpm checks` — all static checks (types + lint + format); default validation for small changes
-- `pnpm check:lint` / `pnpm lint` — lint / lint and fix
-- `pnpm check:format` / `pnpm format` — check / fix formatting
-- `pnpm test` — run all tests
-- `pnpm test <path>` — test files matching a path substring (file, dir, or partial)
-- `pnpm test -t "suite > name"` — test by name, with segments joined by a spaced `>` exactly as the reporter prints them; a single segment such as `-t "renders empty state"` also works (no `--` separator; pnpm forwards args verbatim, unlike npm)
+- `vp check` — format, lint, and type checks; default validation for small changes
+- `vp check --fix` — the same, fixing what it can
+- `vp test` — run all tests once

+- `pnpm dedupe --check` — after a dependency change, confirms the lockfile has no drift; CI runs it

-Vitest collects only the projects listed in `test.projects` of the root `vite.config.ts`, currently just `packages/*`. A test file outside those is never collected, and `pnpm test` still reports green, so adding a new top-level test directory means giving it a `vite.config.ts` and adding it to that list.

 [Vite+](https://viteplus.dev) runs linting, formatting, type checking, tests, and the pre-commit hook. It's a dev dependency, so `pnpm install` is all the setup it needs. Run `pnpm checks` for lint, format, and type checks, `pnpm test` or `pnpm test:watch` for tests, and `pnpm lint` or `pnpm format` to fix issues.

+- If the pre-commit hook never runs, or `pnpm install` prints `core.hooksPath is already set`, the Vite+ hook isn't installed, because your clone or global Git config points hooks somewhere else.
