+# WhisperGate Integration (No-touch Template)
+
+This guide **does not** change your current OpenClaw config automatically.
+It only generates a JSON snippet you can review.
+
+## Generate config snippet
+
+```bash
+node scripts/render-openclaw-config.mjs \
+  /absolute/path/to/WhisperGate/plugin \
+  openai \
+  whispergate-no-reply-v1 \
+  561921120408698910
+```
+
+Arguments:
+1. plugin path
+2. provider alias
+3. model name
+4. bypass user ids (comma-separated, optional)
+
+## Output
+
+The script prints JSON for:
+- `plugins.load.paths`
+- `plugins.entries.whispergate.config`
+
+You can merge this snippet manually into your `openclaw.json`.
+
+## Notes
+
+- This repo does not run config mutation commands.
+- Keep no-reply API bound to loopback/private network.
+- If you use API auth, set `AUTH_TOKEN` and align provider apiKey usage.
