# CLAUDE.md — `about-system` (`packages/about-system-info`)
**npm name:** `about-system` · **skill:** [`skills/about-system`](../../../skills/about-system/SKILL.md)
· **runner:** Vitest · **build:** Vite
Cross-platform CLI + library that prints CPU, memory, disk, uptime, public IP,
ISP and installed tools as one compact emoji line. Designed to be dropped into
`config.fish` / `.zshrc`, so it runs on **every terminal launch**.
## What that implies
- **Startup cost is the product.** Anything you add to the default path is paid
on every shell open. Network lookups (public IP, ISP) go through the cache in
`src/cache/`; keep them off the synchronous path.
- **Three OSes, really.** Windows, macOS and Linux each take a different branch
in `src/info/`. A change that only reads right on Linux is a regression.
- There is a **desktop app** under `native/`, built by
`.github/workflows/about-system-desktop.yml`, with the CLI compiled inside it
so nothing needs installing first.
+ - **`about-system web`** serves a React + shadcn/ui dashboard (`web/`, its own
+ Vite config) plus `GET /api/info` from `src/web-server.ts`. The web build runs
+ *after* the library build because the library build empties `dist/`. React,
+ Tailwind and the shadcn deps are devDependencies — they are bundled into
+ `dist/web`, so the published CLI gains no runtime deps.
+
## Layout
`src/about-system-cli.ts` (bin) · `src/index.ts` (library) ·
`src/info/` (per-block collectors) · `src/cache/` · `src/bench/` ·
- `src/system-info-api.ts` · `src/types/`
+ `src/system-info-api.ts` · `src/web-server.ts` · `src/types/` ·
+ `web/` (dashboard: `src/App.tsx`, shadcn components in `src/components/ui`)
```bash
cd packages/about-system-info
bun run test
bun run build # Vite — consumers get dist/, not src/
```
