Plugins are full-trust code in every runtime. Plugins are on by default. Builtin plugins ship with bb; a few sit behind their own product gates. `bb plugin list` shows each plugin's status. ## Quickstart ``` bb plugin new hello # scaffolds ./bb-plugin-hello (add --app for a frontend entry) cd bb-plugin-hello bb plugin install . # registers the directory in place (--yes to skip the prompt) bb plugin dev # rebuild app/host bundles + reload on every save ``` The manifest is `package.json`: ```json { "name": "bb-plugin-hello", "version": "0.1.0", "type": "module", "engines": { "bb": ">=0.9", "bbPluginSdk": ">=0.4.3" }, "bb": { "name": "Hello", "description": "A friendly example plugin.", "branding": { "icon": "Zap" }, "server": "./server.ts", "app": "./app.tsx", "host": "./host.ts", "skills": ["skills"] } } ``` - `bb.server` (required) — backend entry. Path installs load it as TypeScript directly (no build step); `bb plugin build` also emits a self-contained `dist/server.js` + `server.meta.json` that git/npm installs prefer when its SDK major mat...
