// plan vs build

Two modes. Use the right one.

📐 Plan

Read. Think. Propose.

The agent reads your codebase and writes a step-by-step plan. No files are edited. Review the plan, nudge it in chat, switch to Build when ready.

🔨 Build

Read. Edit. Run.

The agent actually edits your files and runs commands. Pair with git commit for an instant undo button.

🧠

Pro tip

Always start in Plan mode. Read the plan. Clean it up. Then switch to Build. That's vibecoding vs vibepanicking.

Stop reading. Start vibecoding.
