preview

Preview

Launch a local or remote preview of the project using the configured infrastructure provider.

Arguments

• $ARGUMENTS: Optional flags:
  • --status — check current preview status
  • --stop — stop running preview
  • --logs — show preview logs
  • (default) — start/update preview

How to Execute

Step 1: Resolve Provider

Read the preview provider from agency/config/agency.yaml under preview.provider.

# agency.yaml
preview:
  provider: "docker-compose"  # or "fly", "vercel", "cloudflare"

The provider maps to a tool: ./agency/tools/preview-{provider}

Step 2: Check Provider Tool Exists

Verify ./agency/tools/preview-{provider} exists and is executable. If not:

• List available preview tools: ls ./agency/tools/preview-*
• Tell the user which providers are available
• Suggest adding the provider tool if none exist

Step 3: Dispatch to Provider

Execute: ./agency/tools/preview-{provider} {verb} {args}

Where verb is one of: start, stop, status, logs (mapped from flags above, default: start).

Step 4: Report

Show the user:

• Preview URL (if started)
• Status (running, stopped, error)
• Any relevant logs or errors

Provider Contract

Each preview-{provider} tool must support these verbs:

• start — launch preview, print URL to stdout
• stop — tear down preview
• status — print current state (running/stopped/error)
• logs — stream or print recent logs

Error Handling

• If no provider configured in agency.yaml, suggest adding the preview section
• If provider tool missing, list available alternatives
• If provider command fails, show stderr and suggest troubleshooting
