// taskKind labels the dispatch path that the runtime brief should
// follow for a given TaskContextForEnv. Used by
// `buildMetaSkillContentSlim` (MUL-3560 brief; the `runtime_brief_slim`
// flag that once gated it against a legacy verbose brief was retired in
// MUL-4297, so this is now the only brief).
//
// Five kinds, mutually exclusive in practice. classifyTask documents the
// tiebreak rule that applies if a future caller accidentally violates the
// mutex.

// autopilot run-only) and would either render an empty body or steer the
// agent into a guaranteed-failed CLI call. Note this is a kind-based

// kinds always carry an issue id by construction (the daemon refuses to
// dispatch them otherwise), and the other three kinds never do.
