Agent
Modes
Modes change how the agent approaches a task. Pick one from the composer menu before you launch.
Built-in modes
- Build — the default. Plans briefly, then implements the change end-to-end: creates and edits files, runs commands, and verifies until the task is done.
- Plan — thinks first. Produces a concrete, step-by-step implementation plan (files to touch, risks) before writing any code. Great for scoping a large change.
- Debug — reproduces the issue, finds the root cause, and applies the minimal fix, with a short explanation of the cause.
- Multitask — splits the goal into a few independent workers that run in parallel, then brings the results back together.
- Ask — read-only. Answers questions using your codebase as reference without making sweeping edits.
Custom modes
Define your own mode with a label and a system instruction — for example a “Review” mode that only critiques, or a “Docs” mode that writes documentation in your house style. Custom modes appear alongside the built-ins in the composer menu and can fan out across multiple workers like Multitask.
