Claude Code hook designed for read-only observation

By PulseAugur Editorial · [1 sources] ·

The author details how to create a read-only hook for Claude Code, a tool that integrates with AI agents. The hook, named ccdeck, is designed to observe agent behavior without influencing it. The post explains the various communication channels a hook can use to interact with Claude Code, such as standard output, exit codes, and asynchronous responses, and outlines how to ensure the hook remains passive by closing these channels and testing for their inaccessibility. Specific attention is given to preventing unintended steering of the agent by ensuring all execution paths result in a zero exit code and by handling uncaught exceptions to maintain the read-only status.
