 - **Caveman + templates** (`tools/setup-caveman.sh`): Installs Caveman npm
   package, wrapper scripts, and compact output templates for token-efficient
   CLI output. Wrapper at `~/bin/caveman_wrapper.sh`.
+- **Hermes agent persona** (`tools/setup-hermes-soul.sh`): Provisions
+  `~/.hermes/SOUL.md` from `HERMES.md` on Hermes agents. This ensures every
+  Hermes agent follows the canonical homelab persona (token efficiency, source
+  of truth hierarchy). No-op on non-Hermes agents.
