# kei-cost-guardian This is an alias for the **cost-guardian** agent. The real agent prompt is at: `_generated/cost-guardian.md` Manifest source: `_manifests/cost-guardian.toml` Why two files: the `_generated/` form is what `_assembler` writes; the root `kei-cost-guardian.md` form is a discoverability shortcut at repo root. Both reflect the same manifest. Edit the manifest, never these.
