⚠️ Limitations

Limitation	Description
Plan-Bound	Only uses models from your purchased plan
No External	Won't call models outside your plan
Requires Config	Needs correct openclaw.json setup
Memory	Uses 20% more memory for preloading

🔍 Technical Details

Task Classification Algorithm

1. Extract keywords from user request
2. Match against task type keywords
3. Calculate confidence score for each type
4. Select type with highest confidence
5. If confidence < threshold, use default
6. Map type to best model
7. Check model availability
8. Apply fallback if needed

Model Registry

{
  "models": {
    "qwen3.5-plus": {
      "status": "ready",
      "tasks": ["writing", "analysis", "translation"],
      "context": 1000000,
      "priority": 1
    },
    "qwen3-coder-plus": {
      "status": "ready",
      "tasks": ["coding", "debug"],
      "context": 100000,
      "priority": 1
    },
    "qwen3-max": {
      "status": "ready",
      "tasks": ["reasoning", "math"],
      "context": 100000,
      "priority": 1
    }
  }
}

Fallback Chain

Primary Model (Unavailable?)
    ↓
Fallback 1 (Unavailable?)
    ↓
Fallback 2 (Unavailable?)

📝 Installation

# Clone repository
git clone https://github.com/davidme6/openclaw.git

# Copy skill to workspace
cp -r openclaw/skills/smart-model-switcher-v2 ~/.openclaw/workspace/skills/

# Restart Gateway (one-time)
openclaw gateway restart

🔧 Configuration

No configuration needed! The skill auto-detects your plan and available models.

🆘 Troubleshooting

Q: Why didn't it switch models? A: Check logs for fallback events. Primary model may be unavailable.

Q: Can I override the selection? A: Yes, manually specify a model and it will use that.

Q: How do I know which model is being used? A: It always tells you at the start of each task.

Q: Memory usage increased? A: Normal. Model preloading uses 20% more memory for instant switching.
