Struct HookConfig 

pub struct HookConfig {
    pub pre_tool_use: Option<HookHandler>,
    pub post_tool_use: Option<HookHandler>,
    pub on_stop: Option<HookHandler>,
    pub user_prompt_submit: Option<HookHandler>,
}

Hook configuration for tool/lifecycle interception.

Currently honored only by Claude Code (serialized into --settings <json>). Codex/OpenCode treat all hooks as no-ops with a debug-level log.

Fields

pre_tool_use: Option<HookHandler>

Run before every tool use.

post_tool_use: Option<HookHandler>

Run after every tool use.

on_stop: Option<HookHandler>

Run when the session terminates.

user_prompt_submit: Option<HookHandler>

Run when the user submits a prompt.
