Hooks

Anatomy

What it contains

  • An event name and optional matcher
  • A command, prompt, or HTTP action
  • Timeout, dependency, and failure behavior

Lifecycle

How it works

  1. Claude Code emits a lifecycle event
  2. The matcher decides whether the hook applies
  3. The configured action runs automatically
  4. Its result allows, blocks, or annotates the event

Audit lens

What Zebonastic would check

  • Automatic execution is visible and justified
  • Shell input is quoted and validated
  • Timeouts, dependencies, and failure modes are declared
