node-lint

Sets up lint + format so they catch real defects instead of fighting each other. The failures this skill fixes: models write legacy .eslintrc configs that current ESLint majors no longer load, mix two formatters, claim Biome replaces type checking, and reset intentional rule customizations during migrations.

When NOT to use

• Next.js apps → nextjs-quality owns eslint-config-next and RSC rules.
• Type checking / tsconfig → node-typescript (Biome's type-aware rules are not a tsc replacement — never claim otherwise).
• Test setup → node-testing; CI workflow authoring → node-ci.
