Who it is forA developer whose Claude Code limit is nearly used up and who wants to continue the same feature in Codex.
The problemA full transcript is too long to carry into a new client, and the next session loses decisions and verified work.
The outcomeThe new session starts from a handoff listing decisions, unfinished work and what was verified, instead of a transcript.
What you need first
- macOS, Linux or Windows 10/11
- Node.js 24 or newer
- Claude Code and/or Codex installed on the same machine and operating-system user
- A project directory both clients can open
Steps
- Run
npm install -g agents-can-communicateto install ACC. - Run
acc install, follow its activation instructions, and review any required hook or plugin trust. - When the Claude Code session approaches its limit, ask it to leave a handoff with decisions, unfinished work and what was verified.
- Open Codex in the same project so it can pick up the handoff and continue the feature.
- If the handoff does not show up, run
acc doctorfrom the project.
Prompt for your agent
In the agents-can-communicate repo (https://github.com/automatis-tools/agents-can-communicate), use ACC to hand off <feature-name> from a Claude Code session in <project-path> to a Codex session. Expected output: a handoff that lists decisions, unfinished work and what was verified. Verify that the Codex session reads the handoff and confirms the next steps before continuing.
Caveat. The handoff is only as complete as what the outgoing session records, so the receiving session still needs to check the code.
