hook-development

To automate event-driven workflows with Claude Code plugins, you create hooks that execute scripts or prompts in response to events like PreToolUse and PostToolUse. These hooks are defined in a hooks.json file and merged with user settings for comprehensive control over your automation processes.

Prompt-based hooks use LLM-driven decision making for context-aware validation of tool use. Instead of static rules, these hooks evaluate the context of a command before execution, allowing you to block dangerous commands dynamically based on the specific situation.

Yes, creating these advanced hooks requires Claude Code and associated plugins, specifically claudeserver and claudeserver-tools, to function. These dependencies provide the necessary environment and tool validation infrastructure for the event-driven workflows to operate.

You create a PreToolUse hook to block dangerous commands by defining it in your hooks/hooks.json file. This configuration merges with user settings and triggers an automated script or LLM-driven prompt to validate the tool use before the command executes.

Plugin development supports diverse hook types, including both command hooks that execute scripts and advanced prompt hooks that leverage LLMs. These configurations respond to various Claude Code events such as PreToolUse, PostToolUse, and Stop.

While prompt hooks provide context-aware validation using LLMs, they require the full Claude Code environment and associated claudeserver plugins to function. Hook configurations are limited to the specific events supported by the system, such as PreToolUse, PostToolUse, and Stop.
