Struct HookInput 

pub struct HookInput {
    pub session_id: String,
    pub transcript_path: String,
    pub _cwd: Option<String>,
    pub _hook_event_name: Option<String>,
}

What a SessionEnd hook tells us about the session that just ended.

Claude Code’s payload is the reference shape. The camelCase aliases and the defaults are for the other harnesses that can end up invoking this command — Gemini’s hooks migrate --from-claude copies our hook straight into its own settings, and a payload that spells a field differently, or omits it, must produce a clear message rather than a deserialization error on every single session. What is missing is reported by crate::archive::run_with_hook_input, which can say what to do about it.

Fields

session_id: String

transcript_path: String

_cwd: Option<String>

_hook_event_name: Option<String>
