Frequently Asked Questions about Hook Development

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create event-driven Claude Code hooks for plugin development?▼

Yes, PostToolUse hooks can be structured as either deterministic command hooks or flexible prompt-based hooks, allowing you to enforce automated validation or trigger contextual AI interactions after tool execution.

Do I need jq installed to build and validate Claude Code hooks?▼

Yes, jq is a required dependency for hook development, used to parse and validate structured JSON metadata including dependencies, components, and safety evaluations within your plugin configuration.

What is the difference between command hooks and prompt-based hooks in Claude Code?▼

Command hooks execute safe, deterministic shell operations for strict validation, while prompt-based hooks provide flexible, event-driven interactions, allowing you to choose between rigid automation and adaptive AI responses.

How do I ensure security when designing PreToolUse and SessionStart hooks?▼

Security is enforced by applying best practices for deterministic command execution, utilizing provided validation templates, and generating a structured safety evaluation to assess hook behavior before deployment.

What components are required in a valid Claude Code plugin hook package?▼

A valid hook package requires a SKILL.md file containing the name and description, supports optional scripts and references components, and yields structured metadata for dependencies and safety evaluation.
