 Analyze images with two backends: fast cloud (RouterAI gpt-4o-mini) or private local (Gemma 4B via Jan API). Smart routing via emoji flags — NSFW content never touches cloud APIs.
 
+## 🚀 Setup Instructions for AI Agents
+
+### Step 1: Check RouterAI API Key
+
+The script reads the API key from the OpenAI‑style provider config at:
+
+```
+models.providers["routerai-ru"].apiKey
+```
+
+As an agent, you should do this at setup time:
+
+```python
+# Pseudo-code for agents integrating this skill
+try:
+    config = load_config("openclaw.json")  # or your config file
+    api_key = config["models"]["providers"]["routerai-ru"]["apiKey"]
+except (KeyError, FileNotFoundError):
+    api_key = None
+
+if not api_key:
+    # Ask the user for their RouterAI API key
+    api_key = ask_user("🔑 Введите API-ключ RouterAI (https://routerai.ru):")
+    # Write it to your config under models.providers["routerai-ru"].apiKey
+```
+
+The script will work **without** a key only if you always use `--local` (Gemma). However, the default routing goes to RouterAI, so a key is strongly recommended.
+
+**What is RouterAI?** A Russian LLM API aggregator (routerai.ru). Supports many models including gpt-4o-mini, Gemini, Claude. You need an account and an API key. The key is used for fast, cheap vision analysis (~₽0.5 per request).
+
+### Step 2: Check Local Gemma (Optional)
+
+Local Gemma runs on a Jan API / llama.cpp server (http://192.168.88.183:1337). It provides:
+- Free, private image analysis (no external API calls)
+- No censorship filters (handles NSFW/16+ content)
+- Slower (~30-90s per request)
+
+Ask the user:
+
+```python
+has_local = ask_user("💻 Есть локальный сервер Gemma (Jan/llama.cpp) на 192.168.88.183:1337? (y/n)")
+if has_local.lower() in ("y", "yes", "да"):
+    local_url = ask_user("🌐 URL локального сервера:", default="http://192.168.88.183:1337")
+    local_key = ask_user("🔑 API-ключ локального сервера (если нужен):", default="")
+    # Store in your config, e.g. models.providers["jan-local"].apiKey
+else:
+    # Note: --local flag will not work. All requests go to RouterAI.
+    logger.info("Локальная модель не настроена. --local будет недоступен.")
+```
+
+### Step 3: Verify
+
+```bash
+python3 vision-analyze.py test_image.jpg
+# Should return a description in Russian, 3-5 sentences
+```
+
 ## Requirements
 
 - Python 3.10+
 - `ffmpeg` (for image resize)
-- API key in `~/.openclaw/openclaw.json` → `models.providers["routerai-ru"].apiKey`
-- (optional) Local Jan server (`http://192.168.88.183:1337`)
+- RouterAI API key (see Step 1)
+- (optional) Local Jan server for `--local` mode
+
+## Installation
+
+```bash
+# Clone the repo
+git clone https://git.hidosi.ru/Hidosi/agent-scripts-vision-analyze.git
+cd agent-scripts-vision-analyze
+
+# Test without API key (will fail on first request, that's expected)
+python3 vision-analyze.py --help
+
+# Symlink for easy access (optional)
+chmod +x vision-analyze.py
+ln -s "$(pwd)/vision-analyze.py" /usr/local/bin/vision-analyze
+```
