WHAT IT DOES

What export_conversations does on Codex Chats

AI agents use export_conversations to create or update resources in Codex Chats — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Codex Chats environment.

WHY IT NEEDS A POLICY

Why export_conversations needs a policy

This tool writes data to a file on the filesystem. It creates/overwrites a JSON file at the specified output path. It is a Write operation (file creation), not purely Read since it has the side effect of writing to disk. It does not delete, execute code, or involve finances. Severity is medium because it could be used to exfiltrate sensitive conversation data to an attacker-controlled path.
