// plan vs build

Two modes. Use the right one.

๐Ÿ“ 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.

๐Ÿ”จ Build

Read. Edit. Run.

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

๐Ÿง 

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.
