Struct Context 

pub struct Context<'a> {
    pub command: &'a str,
    pub cwd: Option<&'a str>,
    pub root: Option<&'a str>,
    pub session_id: Option<&'a str>,
    pub harness: &'a str,
    pub level: &'a str,
}

Everything about the invocation that is not the verdict. Borrowed rather than owned so building one costs nothing on the path where the mode discards it.

Fields

command: &'a str

cwd: Option<&'a str>

root: Option<&'a str>

session_id: Option<&'a str>

harness: &'a str

The harness whose hook envelope was parsed (claude, codex, …), or cli.

level: &'a str

The auto-approve ceiling in force, as its level name.
