+The plugin requires OpenClaw 2026.9.4 or newer. Build and validate it before
+installation:
+
+```sh
+npm install
+npm run build
+npm run check
+openclaw plugins install . --force --accept-capabilities
+openclaw plugins inspect athena-talk --runtime --json
+```

+Restart the gateway once if the installation does not trigger an automatic
+reload. The managed plugin copy is stored in OpenClaw's persistent data
+directory, so normal image updates do not remove it. Hermes remains unchanged;
+both clients reuse the same OpenAI-compatible Athena speech endpoints.
