**Iterate:**\n- \`shell_exec { projectId, command }\` — anything: \`ls\`, \`npm install\`, \`npm test\`, \`npx create-next-app .\`, \`git status\`. Cwd defaults to \`/workspace\`.

**Dev servers (preview URL via \`*.preview.vibnai.com\` wildcard):**
- \`dev_server_start { projectId, command, port?, name? }\` is a **one-shot** call. It kills old processes on the port, checks the port is free, sets HOST=0.0.0.0 + PORT, launches your command, and returns a clickable \`previewUrl\`. Do NOT pre-flight with \`devcontainer_status\`, \`fs_list\`, \`dev_server_logs\`, or manual \`shell_exec\` kills — the function handles all of that. Just call it. The error tells you what to fix: \`PORT_BUSY\` → pick 3001–3009; \`npm: command not found\` → project needs \`npm install\` first.
- \`port\` defaults to 3000, range 3000–3009 (10 Traefik routers pre-allocated per project).
- **Directory:** The command runs from the root \`/workspace\` directory, but your project code is inside \`/workspace/${activeProject.slug ?? "<slug>"}/\`. You MUST \`cd\` into your project folder first! Example: \`command: "cd ${activeProject.slug ?? "<slug>"} && npm run dev"\`.
- \`dev_server_stop\` / \`dev_server_list\` / \`dev_server_logs\` — use only AFTER a failed start, and only to diagnose the error the function returned. Never on success.

The error tells you what to fix: `PORT_BUSY` → pick 3001–3009; `npm: command not found` → project needs `npm install` first.
- **Port:** The primary frontend service MUST ALWAYS be bound to port `3000`. Do not use any other port for the user-facing UI. If you are spinning up secondary services (like an API or Storybook) alongside it, you may bind them to ports `3001–3009`, but port `3000` is reserved exclusively for the primary visual preview.
- **Directory:** The command runs from the root `/workspace` directory, but your project code is inside `/workspace/${activeProject.slug ?? "<slug>"}/`. You MUST `cd` into your project folder first! Example: `command: "cd ${activeProject.slug ?? "<slug>"} && npm run dev"`.

**HMR through the proxy (apply when scaffolding):**
- **Vite (verified working):** in \`vite.config\` set \`server: { host: '0.0.0.0', port: <3000-3009>, strictPort: true, hmr: { clientPort: 443, protocol: 'wss', host: '<the previewUrl host, no protocol>' } }\`. The \`hmr.host\` is REQUIRED — without it Vite's HMR client can guess the wrong host and the WS handshake fails through Traefik. Default localhost binding looks fine locally but breaks HMR through the proxy.
