Lint Fixer

Fix linting issues while preserving code functionality.

Lint Tools

npm run lint runs 4 tools in sequence:

1. Biome (biome check --write) - Formatter + linter, auto-fixes
2. oxlint (oxlint --fix) - Fast JS/TS linter, auto-fixes
3. tsgo (tsgo --noEmit) - TypeScript type checking
4. secretlint - Detects secrets/credentials

Workflow

1. Run npm run lint to identify issues
2. Review errors by category (type errors vs style vs secrets)
3. Fix issues - Biome/oxlint auto-fix most style issues
4. Run npm run lint again to verify
5. Run npm run test to ensure no breakage

Config Files

• biome.json - Formatting rules (2 spaces, 120 chars, single quotes)
• .oxlintrc.json - JS/TS lint rules
• .secretlintrc.json - Secret detection rules

Key Points

• Biome/oxlint auto-fix most issues; review changes
• Type errors (tsgo) require manual fixes
• Never change code behavior when fixing lint
• Keep files under 250 lines
