biome-lint-format

name: biome-lint-format description: Set up Biome for fast linting and formatting in JavaScript/TypeScript projects, including editor integration, package scripts, optional pre-commit hooks, and migration from ESLint + Prettier. Use when adding or standardizing lint/format tooling, replacing ESLint/Prettier, or troubleshooting Biome configuration and workflow issues.

Biome Lint Format

Set up Biome with a consistent workflow and minimal friction.

Workflow

1. Confirm project context:

• Package manager
• JavaScript/TypeScript scope
• Keep ESLint/Prettier or migrate fully
• Need Tailwind CSS directive support
• Need pre-commit hooks

2. Install Biome and create baseline configuration.

3. Add project scripts for lint/format/check/ci flows.

4. Configure editor integration (VS Code) if requested.

5. Add optional pre-commit checks with Husky + lint-staged if requested.

6. If migrating from ESLint + Prettier, remove old config carefully and run a first auto-fix pass.

7. Validate setup by running check commands and confirming CI command behavior.

Reference Map

Load only the reference needed for the current request:

• references/setup.md Use for installation, baseline biome.json, scripts, VS Code setup, pre-commit setup, and command examples.

• references/migration.md Use only when migrating from ESLint + Prettier or running a hybrid temporary setup.

• references/troubleshooting.md Use for config detection issues, editor conflicts, schema/version mismatches, and performance tuning.

• references/rule-customization.md Use only when the user asks for concrete rule customizations.

Guardrails

• Keep SKILL.md short and procedural; store details in references.
• Use biome check as the default all-in-one command.
• Do not claim Biome replaces tsc type checking.
