pnpm install

Command	What it does
`pnpm dev`	Start the dev server with Turbopack
`pnpm build`	Production build
`pnpm start`	Run the production build
`pnpm lint` / `lint:fix`	ESLint, with autofix
`pnpm format` / `format:check`	Prettier, write or check only
`pnpm typecheck`	TypeScript, no emit
`pnpm test` / `test:watch`	Vitest, once or in watch mode
`pnpm cli`	Run the CLI without installing it globally, e.g. `pnpm cli explain --file src/index.ts`

The same ten tools are available from the terminal, backed by the exact same prompts and validation as the web app.

pnpm cli explain --file src/index.ts

# or install the devtools-ai command globally
npm install -g github:HIMURAw/DevTools-AI
devtools-ai list

See CLI Reference for every install method, every command, and every flag.

Every tool is defined in one place: no new routes required.

Add a prompt builder and Zod schema in src/lib/ai/prompts/
Register the tool in src/config/tools.config.ts with its fields, example input, and output format

The shared route handler, form, output renderer, and CLI command all pick it up automatically.
