Knip Code Cleanup

Run knip to find and remove unused files, dependencies, and exports from this codebase.

Setup

Check if knip is available:

Run npx knip --version to test

If it fails or is very slow, check if knip is in package.json devDependencies

If not installed locally, install with npm install -D knip (or pnpm/yarn/bun equivalent based on lockfile present)

Knip does NOT remove unused imports/variables inside files — that's a linter's job. Knip finds unused files, dependencies, and exports across the project.

Workflow

Always follow this configuration-first workflow. Even for simple "run knip" or "clean up codebase" prompts, configure knip properly before acting on reported issues.
