## Overview

`sn-image-doctor` is an infrastructure skill (tier 0) that validates the SenseNova-Skills environment before running other skills. It ensures SenseNova-Skills project is properly installed and configured.

This skill performs comprehensive checks including:

- Installation verification of SenseNova-Skills project

```bash
# Basic check
python scripts/check_environment.py

## Troubleshooting

### sn-image-base Not Found

**Problem:** `sn-image-base` directory not found

**Solution:**

```bash
# Ensure you're in the project root
cd /path/to/SenseNova-Skills

# Verify the directory exists
ls -la skills/sn-image-base
```

### Missing Dependencies

**Problem:** Required Python packages not installed

**Solution:**

```bash
# Install dependencies
pip install -r skills/sn-image-base/requirements.txt

# Or use a virtual environment
python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
pip install -r skills/sn-image-base/requirements.txt
```

### Missing Environment Variables

**Problem:** Required environment variables not set

**Solution:**

```bash
# Set environment variables in your shell
export SN_IMAGE_GEN_API_KEY="your-api-key"
export SN_IMAGE_GEN_BASE_URL="https://your-api-endpoint.com"

# Or create a .env file
cat > .env << EOF
SN_IMAGE_GEN_API_KEY=your-api-key
SN_IMAGE_GEN_BASE_URL=https://token.sensenova.cn/v1
SN_CHAT_API_KEY=your-chat-api-key
SN_CHAT_BASE_URL=https://token.sensenova.cn/v1
SN_CHAT_TYPE=openai-completions
SN_CHAT_MODEL=sensenova-6.7-flash-lite
EOF

# Load .env file
source .env  # Or use a tool like python-dotenv
```

### API Connectivity Issues

**Problem:** Cannot reach API endpoints

**Solution:**

1. Verify network connectivity
2. Check firewall settings
3. Verify API endpoint URLs are correct
4. Test with curl:

   ```bash
   curl -I https://your-api-endpoint.com
   ```
