To create and validate Claude Code hooks, use structured templates and safety patterns for events like PreToolUse and PostToolUse. This enforces consistent behavior, reliable context injection, and auditable configurations across your projects.

Command hooks execute shell commands for automated checks, while prompt hooks inject context to guide Claude's reasoning. Choosing between command versus prompt hooks depends on whether your workflow requires strict validation or flexible contextual automation.

Set up a PreToolUse hook by defining a configuration in .claude/hooks.json to log and validate Bash commands. Run claude --debug to verify hook matching, inspect inputs, and ensure predictable outcomes before tool execution.

Use SessionStart hooks to initialize project context and UserPromptSubmit hooks to validate or augment user inputs. These event-driven hooks ensure your automation workflows maintain required safety considerations and structured schemas from the beginning.

Yes, you can chain hooks together to build complex event-driven workflows. Chaining hooks allows you to trigger notifications, inject context sequentially, and enforce validation patterns across PreToolUse, PostToolUse, and Stop events reliably.

Hook matching issues often stem from unstructured input/output schemas or incorrect configurations. Run claude --debug to verify hook matching, inspect event inputs, and ensure your hook configurations follow the required safety patterns.
