Hook Inputs & Outputs

Hooks communicate via a standardized JSON interface: Inputs are passed to the hook via stdin, and Outputs are returned via stdout to influence the agent's next move. The input payload typically includes a context object containing session metadata and event-specific data, such as the tool name and its arguments (e.g., the exact code being written or command being run). To respond, your hook must return a JSON object.
