[Bug]: maxOutputTokens must be >= 1 error when using custom provider with oh-my-openagent plugin

Prerequisites

• I will write this issue in English (see our Language Policy)

• I have read the documentation or asked an AI coding agent with this project's GitHub URL loaded and couldn't find the answer

Bug Description

When using oh-my-openagent plugin with a custom OpenAI-compatible provider (local Qwen model), the following error occurs:
Invalid argument for parameter maxOutputTokens: maxOutputTokens must be >= 1
Without the oh-my-openagent plugin, the same custom provider works correctly.

Steps to Reproduce

When I install this plugin, OpenCode stops working properly.
If I remove this plugin from opencode.json, OpenCode works normally again.
I used the same large language model in both scenarios.
This issue only occurs with custom models.
Everything works fine when using OpenCode's built-in free model.
The OpenCode client also works normally; the problem only happens in the command-line environment.

Expected Behavior

opencode should be work when I install oh-my-openagent plugin！

Actual Behavior

Invalid argument for parameter maxOutputTokens: maxOutputTokens must be >= 1

Doctor Output

- OpenCode version: 1.4.3
- oh-my-openagent version: 3.17.2
- OS: Windows 11
- Provider: Custom OpenAI-compatible (@ai-sdk/openai-compatible)
- Model: Local Qwen3.6Plus via http://127.0.0.1:8317/v1

I'm having the same issue. I've been staying on version 1.5.3.This version is good.

1.5.3 Is OMO version? I couldn't find it in the release list.

[JiGuangYuan]

@Cenariuser OMO version 3.15.3 My apologies, I misspoke.

我也遇到了；
同样是：

• OpenCode version: 1.4.3
• oh-my-openagent version: 3.17.2
  我的解决办法是：
  修改 ~/.config/opencode/oh-my-openagent.json
  给每个agent添加”"maxTokens": 4096,“

例如：

  "agents": {
    "sisyphus": {
      "maxTokens": 4096,
      "model": "opencode/minimax-m2.5-free",
      "variant": "max",
      "fallback_models": [
        {
          "model": "opencode/kimi-k2.5"
        },
        {
          "model": "opencode/gpt-5.4",
          "variant": "medium"
        },
        {
          "model": "opencode/glm-5"
        },
        {
          "model": "opencode/big-pickle"
        }
      ]
    },
}

May I ask when the official can fix it?
It's been stuck here for a day and it's really frustrating.
