Integrate with WorkBuddy ​

WorkBuddy is a desktop-level AI Agent from the Tencent Cloud CodeBuddy team. It drives local file operations through natural language, runs multiple agents in parallel, and supports custom models via the OpenAI-compatible protocol.

I. Prerequisites ​

Obtain your API Key from the LongCat Platform, and confirm on the Usage page that your account has sufficient token quota.

The LongCat API platform currently provides the following models:

Model NameAPI FormatDescription
LongCat-2.5-PreviewOpenAI/AnthropicHigh-performance agentic model
LongCat-2.0OpenAI/AnthropicHigh-performance agentic model

II. Install WorkBuddy ​

Download and install from the WorkBuddy website. Windows and macOS are supported.

III. Configure the LongCat Model ​

  1. Open WorkBuddy. In the New Task dialog, at the model switcher, click Configure Custom Model.

work-buddy-open-config

  1. On the Add Model page, select Custom (or OpenAI-compatible) as the provider, and fill in:
    • API URL: https://api.longcat.chat/openai/v1/chat/completions
    • API KEY: your LongCat API Key
    • Model Name: LongCat-2.5-Preview

work-buddy-add-model

  1. Click Save to finish.

Option 2: Configuration file models.json ​

Create or edit the configuration file:

  • macOS: ~/.workbuddy/models.json
  • Windows: <User Home>\.workbuddy\models.json

Write the following into the file:

json
{
  "models": [
    {
      "id": "LongCat-2.5-Preview",
      "name": "LongCat-2.5-Preview",
      "vendor": "LongCat",
      "url": "https://api.longcat.chat/openai/v1/chat/completions",
      "apiKey": "LongCat API Key",
      "supportsToolCall": true,
      "supportsReasoning": true
    }
  ]
}

Fill the apiKey field with the API Key you obtained from the LongCat Platform. Restart WorkBuddy for the changes to take effect.

Project-level configuration is also supported: create <project root>/.workbuddy/models.json. Project-level configuration takes precedence over user-level configuration.

IV. View and Switch Models ​

Once configured, turn off Auto mode and open the model list to see the configured LongCat model.

V. Usage ​

Select the configured LongCat-2.5-Preview model, then start chatting, coding, and more.

VI. FAQ ​

The model does not appear in the dropdown after configuration?

  • Check that models.json is valid JSON and saved as UTF-8 without BOM.
  • Confirm the file is in the correct directory (~/.workbuddy/models.json).
  • Fully restart WorkBuddy and check again.

Authentication failure or 401?

  • Verify the API Key is a valid LongCat API Key, and that you did not swap the API Key and API URL fields.

Model not found or 404?

  • Verify the model id is exactly LongCat-2.5-Preview and the API URL is https://api.longcat.chat/openai/v1/chat/completions.
