# jiti Fast Runtime TypeScript and ESM Loader

Integrates UnJS jiti: loading dynamic TypeScript configuration files (e.g. tailwind.config.ts, custom plugins), filesystem caching, ESM/CJS interop, and syntax transformation without global process hooks.

## When to Invoke
Invoke this skill whenever you need to:
- use jiti to load ts config
- dynamic import typescript jiti
- jiti cjs esm interop

## Execution SOP & Rules
1. Install package: pnpm add jiti.
2. Create loader: const jiti = require('jiti')(__filename); or import createJiti from 'jiti'.
3. Require TypeScript file directly: const config = jiti('./my-config.ts');.
4. Inspect loaded module and verify default export unwrapping works as expected.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
