 ## Installation
 
 - ComfyUI-Manager: install as a custom node (recommended for most users), then restart ComfyUI.

 For the full step-by-step guide (where to put exported workflow JSON, how to author `manifest.json`, how to verify `/openclaw/templates`, and how to use `/run`), see `tests/TEST_SOP.md`.
 
+### Basic `/run` usage (chat)
+
+**Free-text prompt mode (no `key=value` needed):**
+
+```
+/run z 画面中央是一位年轻女性… seed=-1
+```
+
+The connector will map the free text into a prompt field using:
+
+- `allowed_inputs` if a single key is declared in `manifest.json`, or
+- fallback order: `positive_prompt` → `prompt` → `text` → `positive` → `caption`.
+
+**Key=value mode (explicit mapping):**
+
+```
+/run z positive_prompt="a cat" seed=-1
+```
+
+Important:
+
+- Ensure your workflow uses the same placeholder (e.g., `"text": "{{positive_prompt}}"`).
+- `seed=-1` gives random seeds; a fixed seed reproduces outputs.

 Set webhook auth env vars (see “Quick Start”) and restart ComfyUI.
 
+### Admin Token: server-side vs UI
+
+`OPENCLAW_ADMIN_TOKEN` is a **server-side environment variable**.  
+The Settings UI can **use** an Admin Token for authenticated requests, but **cannot set or persist** the server token.

+# OpenClaw Connector Security Checklist
+
+> **Complete this checklist before enabling public ingress (tunnel, reverse proxy, or direct exposure).**
+
+## ✅ Pre-Deployment Checklist
+
+### 1. Authentication & Trust
+
+- [ ] Set `OPENCLAW_CONNECTOR_ADMIN_USERS` with at least one admin ID.
+- [ ] Configure platform-specific allowlists:
+  - Telegram: `OPENCLAW_CONNECTOR_TELEGRAM_ALLOWED_USERS` / `_ALLOWED_CHATS`
+  - Discord: `OPENCLAW_CONNECTOR_DISCORD_ALLOWED_USERS` / `_ALLOWED_CHANNELS`
+  - LINE: `OPENCLAW_CONNECTOR_LINE_ALLOWED_USERS` / `_ALLOWED_GROUPS`
+- [ ] Verify startup banner shows "No trusted users" warning if allowlists are empty.
+
+### 2. Webhook Security (LINE)
+
+- [ ] HTTPS only — never expose webhook over HTTP.
+- [ ] Verify `OPENCLAW_CONNECTOR_LINE_CHANNEL_SECRET` is set (signature verification).
+- [ ] Consider using a randomized webhook path (e.g., `/line/webhook-abc123def`).
+
+### 3. Rate Limiting
+
+- [ ] Review default limits: 10 req/min per user, 30 req/min per channel.
+- [ ] Adjust if needed: `OPENCLAW_CONNECTOR_RATE_LIMIT_USER_RPM`, `_CHANNEL_RPM`.
+
+### 4. Payload Limits
+
+- [ ] Default max command length: 4096 chars.
+- [ ] Adjust if needed: `OPENCLAW_CONNECTOR_MAX_COMMAND_LENGTH`.
+
+### 5. Server API Access
+
+- [ ] Keep ComfyUI on localhost (`--listen 127.0.0.1`) unless LAN access required.
+- [ ] If exposing to LAN/Internet: set `OPENCLAW_ADMIN_TOKEN` environment variable.
+- [ ] Never expose admin endpoints without token.
+
+### 6. Debug Mode
+
+- [ ] `OPENCLAW_CONNECTOR_DEBUG=1` logs sensitive data — **disable in production**.
+- [ ] Ensure no debug flags are set in production environment.
+
+### 7. Tunnel / Reverse Proxy
+
+- [ ] Use ngrok, Cloudflare Tunnel, or similar with TLS termination.
+- [ ] Restrict access by IP if possible.

+## Admin Token & UI Usage (SOP)
+
+**Key rule:** `OPENCLAW_ADMIN_TOKEN` is a **server-side environment variable**.  
+The UI can **use** an Admin Token for authenticated requests, but **cannot set or persist** the server token.
+
+### Recommended setup (local only)
+1) **Set server token (env)**
+```powershell
+$env:OPENCLAW_ADMIN_TOKEN="your_admin_token_here"
+```
+2) **Restart ComfyUI**
+3) **Enter the same token in the Settings UI**
+   - This only stores it in the browser session for API calls.
+
+### Windows CMD (per-session)
+```cmd
+set OPENCLAW_ADMIN_TOKEN=your_admin_token_here
+set OPENCLAW_LLM_API_KEY=your_api_key_here
+set OPENCLAW_LLM_PROVIDER=gemini
+```
+
+### Windows CMD (persistent, user-level)
+```cmd
+setx OPENCLAW_ADMIN_TOKEN "your_admin_token_here"
+setx OPENCLAW_LLM_API_KEY "your_api_key_here"
+setx OPENCLAW_LLM_PROVIDER "gemini"
+```
+
+> After `setx`, open a **new** terminal session before launching ComfyUI.
+
+### Security Notes
+- Do **not** expose ComfyUI to the internet with UI-only tokens.
+- Admin token must remain server-side and protected by OS/environment.
