Oh My Opencode Model Switcher

Model Switcher

This skill enables switching model configurations in oh-my-opencode.json between different modes:

• default: Original model settings
• economy: All models set to opencode/glm-4.7-free

Additional modes can be easily added by editing the mapping configuration.

Usage

When the user requests to switch models or activate a specific mode, use this skill to update the configuration.

Workflow

Switch to a Mode

Execute the switch script with the desired mode:

python3 ~/.config/opencode/.claude/model-switcher/scripts/switch_models.py [mode_name]

Examples:

• python3 ... switch_models.py economy - Switch to economy mode
• python3 ... switch_models.py default - Switch to default mode

List Available Modes

python3 ~/.config/opencode/.claude/model-switcher/scripts/switch_models.py --list

How It Works

1. Mapping-based approach: Model assignments are defined in config/model-mappings.yml
2. Partial updates: Only specified models are updated, preserving other settings
3. Wildcard support: Use "*" to apply a model to all agents/categories
4. Field preservation: Other fields like variant are kept unchanged
5. Structure-resilient: New agents/categories in oh-my-opencode.json are preserved

Configuration

Edit config/model-mappings.yml to:

• Add new modes
• Modify existing mode mappings
• Define per-agent/category model assignments

Example mapping structure:

modes:
  mode_name:
    agents:
      agent_name: model_name
      # or use "*" for all agents
    categories:
      category_name: model_name
