Adds Oxlint as a third toolchain option next to ESLint and Biome, for both React and Solid. You can pick it from the toolchain prompt or with --toolchain oxlint.
It's lint-only for now (no Oxfmt yet). A new project gets:
an .oxlintrc.json
a lint script and the oxlint dev dependency
a short Linting section in the generated README
React config
It uses Oxlint's default correctness rules plus the React plugin, adjusted to match the recommended preset in eslint-plugin-react-hooks:
rules-of-hooks is turned on. Oxlint leaves it off by default.
exhaustive-deps, incompatible-library and unsupported-syntax are warnings. As an error, incompatible-library flags TanStack Table's useReactTable.
purity and set-state-in-effect are off because the base scaffold trips them (new Date() in the footer and the theme toggle's effect).
Solid uses the same setup without the React plugin.
Testing
Added tests in packages/create/tests/toolchains.test.ts
These scaffolds lint clean: React default, blank, router-only and Rsbuild; Solid default, blank and Rsbuild
tanstack add oxlint works on an existing Rsbuild project, and adding ESLint after that is blocked as expected
Installed, linted and built a default React app
Some add-on demo pages still have lint errors under Oxlint. Biome's toolchain fails on them too, so I've left them for a separate PR.
Summary by CodeRabbit
New Features
Added Oxlint as a linter option when creating React and Solid projects. Generated projects include Oxlint configuration, a lint command, and setup guidance.
The React config enables react/rules-of-hooks (Oxlint puts it in the off-by-default
pedantic category) and sets exhaustive-deps, incompatible-library and
unsupported-syntax to warn, matching eslint-plugin-react-hooks' recommended preset.
purity and set-state-in-effect are off because the base scaffold triggers them.
React and Solid scaffolds now support Oxlint with generated configuration and a lint script. CLI validation and scaffold references list Oxlint as a toolchain option, and the documentation describes its setup.

Summary
Define and generate Oxlint setup packages/create/src/frameworks/{react,solid}/toolchains/oxlint/*, packages/create/src/frameworks/{react,solid}/project/base/README.md.ejs, packages/create/tests/toolchains.test.ts
React and Solid scaffolds gain Oxlint metadata, configuration, and a lint script. Their generated READMEs describe the lint command. Tests check toolchain registration and generated output.
Expose Oxlint in CLI support and documentation domain_map.yaml, packages/cli/src/command-line.ts, packages/cli/skills/create-app-scaffold/references/*, ARCHITECTURE.md, frameworks/FRAMEWORK-STRUCTURE.md, cli-aliases/*/README.md, .changeset/oxlint-toolchain.md
CLI validation messages, scaffold references, and framework documentation include Oxlint. CLI alias READMEs describe its generated configuration, and the changeset records the option for React and Solid scaffolds.
Blank projects can still run Oxlint, but their READMEs do not explain the lint command. This is a bounded documentation gap, not a blocker to using the toolchain.

Include the Oxlint instructions in blank scaffolds.
When projectPreset is blank, this section does not render because it sits inside the nonblank README branch. The generated package still has a lint script, but the README does not document it. The Solid template has the same gap at Line 146. Add the Linting section to both blank branches, or place it outside the blank/nonblank conditional. (raw.githubusercontent.com)
