# Agent handoffs

> How Composer keeps work moving across Claude and Codex.

Agent handoffs are the central Composer workflow. Instead of copying summaries between separate terminal sessions, you continue the same work through a shared Composer thread.

## Common patterns

### Plan, then review

Use one agent to propose an approach, then switch to another agent to critique edge cases, risks, and missing tests before implementation starts.

### Plan, then execute

Use one agent for architecture or sequencing, then switch to another agent to make the code changes and verify them.

### Start both, pick one

Send the same prompt to multiple agents, compare their first pass, and continue from the thread that best fits the task.

### Switch on the next turn

Choose the agent that fits the next prompt without abandoning the surrounding conversation or workspace state.

## What carries forward

* The user goal and conversation context.
* The active project workspace.
* Local file and branch state.
* The latest implementation and verification notes.
