Subtask commands do not inherit model

[JUVOJustin]

Description

If running a command as a subtask, the model is not inherited from the agent but from the config.

Config

{
    "$schema": "https://opencode.ai/config.json",
    "autoupdate": true,
    "model": "opencode/big-pickle",
    "agent": {
        "build": {
            "model": "github-copilot/claude-sonnet-4.5",
            "permission": {
                "external_directory": "deny",
                "context7*": "allow"
            }
        },
        "plan": {
            "model": "github-copilot/gpt-5.1",
            "permission": {
                "external_directory": "deny",
                "context7*": "allow"
            }
        },
        "explore": {
            "model": "opencode/big-pickle"
        }
    },
    "mcp": {
        "context7": {
            "type": "remote",
            "url": "https://mcp.context7.com/mcp"
        }
    }
}

Steps to reproduce

1. New session
2. Switch to another model than the agents default model. e.g. GLM 4.7
3. Run the command
4. Switch in the session of the command and see that the default model is used despite the previous selection
5. Be sad that your precious github copilot premium requests are used
