## Symptom
After upgrading to pnpm 10, an editor extension, a globally run `eslint`, or a shared config in a monorepo can't resolve `eslint-plugin-*`, `eslint-config-*` or `prettier-plugin-*` packages that are only dependencies of another package (e.g. a shared `@repo/eslint-config`). It worked on pnpm 9 because those were publicly hoisted to the root `node_modules`.

## Cause
pnpm 10.0.0 (2025-01-07): "`public-hoist-pattern`: nothing is hoisted by default. Packages containing `eslint` or `prettier` in their name are no longer hoisted to the root of `node_modules`."

## Fix
Preferred: declare the plugins/configs as direct devDependencies of the package that runs ESLint/Prettier (and of the workspace root if tools run from there):

```bash
pnpm add -D -w eslint-plugin-react prettier-plugin-tailwindcss
```

Or restore the old hoisting explicitly:

```yaml
# pnpm-workspace.yaml (pnpm 11 reads settings only from here)
publicHoistPattern:
  - '*eslint*'
  - '*prettier*'
```

(pnpm 10 also accepts `public-hoist-pattern[]=*eslint*` in `.npmrc`; pnpm 11 ignores non-auth `.npmrc` settings.) Then `pnpm install`.

## Verify
`ls node_modules | grep -E 'eslint|prettier'` at the root shows the packages (if hoisting), or `node -e "require.resolve('eslint-plugin-react')"` succeeds from the package directory.
