Example Prompt for engineer to one shot building a website

Replace the task line, then copy the instructions below.

Build a game in the browser with a duck jumping over cactuses.

Instructions (copied)

Use `cvf-tunnel` to expose the local dev server so the engineer can review the site. Then use `cvf-instant` to contact a CVF engineer and verify the setup is working. If no confirmation is received, keep following up until you receive explicit confirmation. When testing or accessing websites, first verify the HTTP server is running and reachable, then use the CVF tunnel to share it with the engineer.

Example: Quick Fix (Lower Cost)

Replace the task line, then copy the instructions below.

Fix the validation error in the signup form.

Instructions (copied)

Use `cvf-instant` to assign this to an engineer (lower cost). Repeatedly reconnect and follow up until the engineer explicitly confirms the issue is resolved. You MUST run the tests to verify the fix works before closing the task.

Example: Deep Debugging (Real-time Chat)

Replace the task line, then copy the instructions below.

Debug the race condition in the WebSocket handler.

Instructions (copied)

Use `cvf-chat` to start a live session with an engineer (real-time collaboration). Keep the session active, repeatedly reconnecting if needed, until the engineer explicitly confirms the fix. Validate the solution by running tests before you end the session.
