# sn-image-doctor

## 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
- Python dependency validation
- Environment variable configuration checks, with interactive prompts to configure missing required variables and save them to `.env`
- Automatic environment reload after configuration changes, with agent restart suggestion if reload fails

## Usage

Run the doctor check to validate your environment:

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

# Verbose output with detailed diagnostics
python scripts/check_environment.py --verbose
```

## Output Format

### Text Output

```
=== SenseNova-Skills Environment Check ===

[1/3] Checking sn-image-base installation...
  ✅ Installation looks good

[2/3] Checking Python dependencies...
  ✅ Python 3.11.0
  ✅ All required packages installed

[3/3] Checking environment variables...
  ❌ SN_IMAGE_GEN_API_KEY: Image generation API key is not set; configure SN_API_KEY, or configure SN_IMAGE_GEN_API_KEY only for an image-generation-specific override

  Some required environment variables are missing.
  Enter values below to save them to /path/to/.env.
  Press Enter to skip a variable.

  SN_API_KEY: <user input>

  ✅ Saved to /path/to/.env: SN_API_KEY
  🔄 Reloading environment...
  ✅ Environment reloaded successfully

=== Summary ===
✅ Environment is properly configured
```

If reload fails, the output will suggest restarting the agent:

```
  ✅ Saved to /path/to/.env: SN_API_KEY
  🔄 Reloading environment...
  ⚠️  Failed to reload environment: <error message>
  💡 Suggestion: Restart the agent to apply new configuration
```

### Error Output

When checks fail:

```
=== SenseNova-Skills Environment Check ===

[1/3] Checking sn-image-base installation...
  ❌ sn-image-base directory not found
  Expected location: /path/to/skills/sn-image-base

[2/3] Checking Python dependencies...
  ❌ Missing packages: httpx, pillow
  Run: pip install -r skills/sn-image-base/requirements.txt

=== Summary ===
❌ Environment check failed
Please fix the errors above before using SenseNova-Skills.
```

## 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
# If all capabilities use the same gateway, set only the global values.
export SN_API_KEY="your-api-key"
export SN_BASE_URL="https://your-api-endpoint.com"

# Or create a .env file
cat > .env << EOF
SN_API_KEY=your-api-key
SN_BASE_URL=https://token.sensenova.cn/v1
SN_CHAT_TYPE=openai-completions
SN_CHAT_MODEL=sensenova-6.8-flash-lite
EOF

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

Fallback priority is capability-specific variable > domain shared variable > global variable. For example, text calls use `SN_TEXT_API_KEY` -> `SN_CHAT_API_KEY` -> `SN_API_KEY`; vision calls use `SN_VISION_API_KEY` -> `SN_CHAT_API_KEY` -> `SN_API_KEY`; image generation uses `SN_IMAGE_GEN_API_KEY` -> `SN_API_KEY`.

### 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
   ```

## Integration with Other Skills

This skill is designed to be run before using other skills in the SenseNova-Skills project:

```bash
# 1. Run doctor check
python skills/sn-image-doctor/scripts/check_environment.py

# 2. If checks pass, use other skills
python skills/sn-image-base/scripts/sn_agent_runner.py sn-image-generate \
    --prompt "A beautiful landscape"
```
