How does the skill prevent hooks from failing silently?

It includes automated checkpointing that verifies hook scripts exit with the correct codes and produce valid, parseable JSON matching the event-specific schema.

What types of hooks can I create with this skill?

You can create command hooks for deterministic logic, prompt hooks for LLM-based decisions, HTTP hooks for external integrations, and agent hooks for complex multi-step tasks.

Does this skill handle the registration process?

Yes, it verifies and assists in adding hook entries to the hooks section of your target plugin's plugin.json file to ensure they are active.

Can I use this to restrict Claude's tool usage?

Yes, by implementing a PreToolUse hook, you can create logic to block or allow specific tools based on the current context or security requirements.
