Struct HookSpec 

pub struct HookSpec {
    pub file_name: &'static str,
    pub body: &'static str,
    pub hook_event: &'static str,
}

One hook spec to render and write under ~/.claude/hooks/.

Fields

file_name: &'static str

File name on disk (e.g. spool-SessionStart.sh). Always prefixed with spool- so uninstall can sweep files via prefix matching without affecting unrelated tools.

body: &'static str

Raw template body before substitution.

hook_event: &'static str

The Claude Code hook event this script implements. We use this to wire the entry under ~/.claude/settings.json hooks.
