# Vercel CLI
You can deploy web applications to Vercel using the `vercel` CLI.
## Auth
Auth is handled by OneCLI — the HTTPS_PROXY injects the real token into API requests automatically. The Vercel CLI requires a token to be present to skip its local credential check, so **always pass `--token placeholder`** on every command. OneCLI replaces this with the real token at the proxy level.
Before any Vercel operation, verify auth:
```bash
vercel whoami --token placeholder
```
If this fails with an auth error, collect the credential:
```
trigger_credential_collection(
name: "Vercel API Token",
hostPattern: "api.vercel.com",
headerName: "Authorization",
valueFormat: "Bearer {value}",
description: "Vercel personal access token. Create one at https://vercel.com/account/tokens"
)
```
Then retry `vercel whoami`.
## Deploying
Always use `--yes` to skip interactive prompts and `--token placeholder` for auth (OneCLI replaces with real token).
```bash
# Deploy to production
vercel deploy --yes --prod --token placeholder
# Deploy from a specific directory
vercel deploy --yes --prod --token placeholder --cwd /path/to/project
# Preview deployment (not production)
vercel deploy --yes --token placeholder
```
After deploying, verify the live URL:
```bash
# Check deployment status
vercel inspect <deployment-url> --token placeholder
```
If you have `agent-browser` available, open the deployed URL and take a screenshot to visually verify.
## Project Management
```bash
# Link to an existing Vercel project (non-interactive)
vercel link --yes --token placeholder
# List recent deployments
vercel ls --token placeholder
# List all projects
vercel project ls --token placeholder
```
## Domains
```bash
# List domains
vercel domains ls --token placeholder
# Add a domain to the current project
vercel domains add example.com --token placeholder
```
## Environment Variables
```bash
# Pull env vars from Vercel to local .env
vercel env pull --token placeholder
# Add an env var (use echo to pipe the value — avoids interactive prompt)
echo "value" | vercel env add VAR_NAME production --token placeholder
```
## Common Errors
| Error | Fix |
|-------|-----|
| `Error: No framework detected` | Ensure the project has a `package.json` with a `build` script, or set the framework in `vercel.json` |
| `Error: Rate limited` | Wait and retry. Don't loop — report to user |
| `Error: You have reached your project limit` | User needs to upgrade Vercel plan or delete unused projects |
| `ENOTFOUND api.vercel.com` | Network issue. Check proxy connectivity |
| Auth error after `vercel whoami` | Credential may be expired. Re-run `trigger_credential_collection` |
## Building Websites — Delegate to Frontend Engineer
When asked to **build, create, or redesign** a website or web app, do NOT build it yourself. Spin up a dedicated frontend-engineer agent that has full context for the job:
```
create_agent({
name: "Frontend Engineer",
instructions: "You are a dedicated frontend engineer. Your frontend-engineer skill has your full workflow. Build what is requested, test it visually with agent-browser, deploy to Vercel, and send back the live URL + screenshots to your parent agent when done."
})
```
Then hand off the task:
```
send_message(to: "Frontend Engineer", text: "<what to build, design requirements, any assets or content>")
```
The frontend agent will:
1. Build the site following pro frontend standards
2. Test visually with `agent-browser` (screenshots as proof)
3. Deploy to Vercel using `vercel deploy --yes --prod --token placeholder`
4. Verify the production URL in browser
5. Send back the live URL + screenshots
**When to delegate vs do it yourself:**
- **Delegate**: building new sites, redesigns, multi-page apps, anything that needs visual testing
- **Do yourself**: simple `vercel deploy` of an existing project, checking deployment status, managing domains/env vars
## Best Practices
- Run `npm run build` locally before deploying to catch build errors early
- Use `--cwd` instead of `cd` to keep your working directory stable
- For Next.js projects, `vercel deploy` auto-detects the framework — no extra config needed
- Use `vercel.json` only when you need custom build settings, rewrites, or headers
