Module hooks 

Tool hook system — PreToolUse / PostToolUse event interception.

Hooks run synchronously in the tool execution path. A hook can allow, block, or (future) modify a tool call. Multiple hooks are checked in registration order; the first Block wins.

Enforces allow / deny rules from PermissionRulesConfig.

Enums

HookDecision

Decision returned by a hook’s before_tool_use method.

Traits

ToolHook

Hook that runs before and after every tool execution.

Functions

run_post_hooks

Helper: run all registered hooks after a tool call.

run_pre_hooks

Helper: run all registered hooks before a tool call. Returns HookDecision::Block on first blocking hook; otherwise Allow.
