 ## Code Style
 
-### Biome Configuration
+### Formatting and linting
+
 - 2 spaces, double quotes, semicolons
-- Max line: 100 chars
+- Formatter width: 80 characters
 - Trailing commas in multiline
+- MCP and root files use Oxfmt and Oxlint; CLI files still use their own Biome rules.
+- CLI's custom Grit rules and inline suppressions remain active until their
+  equivalents are available in the new linter.
 
 ### Naming Conventions
+
 - Files: `kebab-case.ts`
 - Functions: `camelCase`
 - Types/Classes: `PascalCase`
 - Constants: `UPPER_SNAKE_CASE`

 pnpm -w run lint:fix    # Fix issues
