Description

The model field in slash command YAML frontmatter appears to be ignored, causing commands to fall back to the default model without any user notification.

This is documented in the [commands[(https://opencode.ai/docs/commands/) section of the docs, suggesting that the docs are out of sync.

Steps to Reproduce

  1. Create .opencode/command/test.md:

    ---
    description: "Test command with specific model"
    agent: plan
    model: cerebras/qwen-3-coder-480b
    ---
    
    This is a test command.
    
  2. Run the command: /test

  3. Observe that the command executes with the default model instead of the specified model

Tested with cerebras/qwen-3-coder-480b, github-copilot/claude-sonnet-4 and anthropic/claude-sonnet-4-20250514. Neither of the 3 models worked in the 'model' field.

This issue might be a duplicate of existing issues. Please check:

  • #2335: Chosen model is not used for command - This was about the model selection being ignored when running custom commands, which appears to be the exact same issue you're reporting with the model field in YAML frontmatter being ignored.

Feel free to ignore if none of these address your specific case.
