What problem does it solves? Automating repetitive tasks and enforcing best practices within Claude Code workflows can be challenging without a structured way to manage lifecycle events. This skill simplifies the creation, configuration, testing, and debugging of hooks, enabling seamless automation and validation.
PreToolUse hook that checks the Git command and blocks git push --force if it targets a protected branch, ensuring code integrity and preventing costly errors.Create a hook to log all bash commands. List all configured hooks. Test the 'file-protection' hook with a sample input.

Hooks automate workflows by executing scripts at 9 lifecycle events—PreToolUse, PostToolUse, UserPromptSubmit, SessionStart, SessionEnd, Stop, SubagentStop, PreCompact, and Notification. Configure JSON-based hooks at project or user level to run deterministic automation, validation, and security checks without manual intervention.
Claude Code hooks enforce security policies, validate inputs, and automate tasks at specific workflow points. Common uses include blocking dangerous Git commands, logging bash activity, auto-formatting code, and enforcing coding standards to prevent errors and ensure compliance.
Yes. Create a PreToolUse hook that inspects Git commands and blocks `git push --force` on protected branches. The hook receives tool metadata, evaluates conditions, and returns exit code 2 to block the operation, preventing costly mistakes.
Define hooks as strict JSON configurations stored at project or user level under the ${CLAUDE_PLUGIN_ROOT} convention. Test hooks by submitting sample inputs to validate logic before deployment. The system supports exit codes 0 (success) and 2 (blocking) plus non-blocking errors.
Claude Code supports 9 lifecycle events: PreToolUse and PostToolUse for tool execution, UserPromptSubmit for input validation, SessionStart and SessionEnd for setup and cleanup, Stop and SubagentStop for interruption handling, PreCompact for context management, and Notification for alerts.
Hooks use declarative JSON configuration, not complex scripting. The Skill provides 13 pre-built patterns for logging, safety checks, and notifications that you can adapt to your workflow. Quick-start guides help you create your first hook in minutes.
