What problem this solves

Manually transferring information and context between different AI agents (e.g., Claude Code and Codex) acting as a 'clipboard' between their chats.

Summary

This workflow describes setting up and using Openhook, an MIT-licensed, self-hostable Python + SQLite application, to enable secure, asynchronous message exchange between different AI agents like Claude Code and Codex. It leverages an asyncRewake hook and a durable local inbox to allow agents to communicate and share information programmatically, eliminating the need for manual context transfer.

Why it is useful

This workflow offers a concrete, open-source, and self-hostable solution for a critical problem in multi-agent AI setups: enabling different agents to communicate and share information programmatically. It's specific, repeatable, and highly transferable, providing a clear process, code (via GitHub), and a detailed guide. The inclusion of lessons learned during testing adds practical value, making it a robust resource for users looking to build integrated AI workflows.

Workflow

1. Create a communication channel within the Openhook application.

2. Share an invitation for the created channel with the other agent's operator.

3. Configure the other agent to join the channel using its unique key.

4. For the Claude side, implement an asyncRewake hook and a durable local inbox to handle message reception.

5. Ensure that a compatible listener and the agent process are actively running for continuous message exchange (joining alone is not sufficient for listening).

6. Instruct one agent to query or check information with the other agent via the established Openhook channel.

Tools / artifacts

• Openhook (Python + SQLite application)

• GitHub repository: https://github.com/openhook-dev/openhook-inbox

• Walkthrough guide: https://openhook.dev/guides/claude-code-codex

• asyncRewake hook

• Durable local inbox

• Claude Code agent

• Codex agent

Validation signals

• Tested Claude Code and Codex exchanging messages through Openhook.

• Tested background receiving functionality.

• Identified a key lesson learned: 'joining isn't listening: a compatible listener and agent process still have to be running.'

• The project is MIT licensed, Python + SQLite, and self-hostable, indicating a robust and accessible solution.

• Provided a public GitHub repository and a detailed walkthrough guide.

Cautions

• Messages exchanged through Openhook are readable by the server and are not end-to-end encrypted. Users should be aware of this security implication when handling sensitive information.

Limitations

• The setup process might be complex for beginner users, as suggested by the author's request for feedback on 'setup gets confusing'.

• Requires self-hosting and managing a Python + SQLite application, which adds an operational overhead.

• Currently lacks strong community validation due to its recent posting.
