authoring-tool-hook

What problem does it solve?

This Skill helps you author Claude Code hooks that control runtime behavior, audit events, and enforce security policy without confusing hooks with ordinary configuration.

Core Features & Use Cases

• Choose the right hook event for the job, including PreToolUse, PostToolUse, SessionStart, SessionEnd, UserPromptSubmit, Stop, SubagentStop, and Notification.
• Write scripts that read JSON from stdin, return allow or block decisions on stdout, and register them in settings.json or a plugin manifest.
• Use it when blocking dangerous Bash commands, logging tool activity, injecting session context, or handling external policy checks with explicit timeout, cache, and failure-mode rules.

Quick Start

Ask Claude to draft a PreToolUse hook that blocks risky Bash commands, then have it explain the JSON payload, the decision response, the registration path, and the security review steps.
