Hello !
Opencode is amazing because of its possibility with different provider however I do not find the provider I'm currently using which is https://www.augmentcode.com/ would it be possible to add it to the supported list ?

Thank you again for your amazing work

Augment has a CLI (auggie), and it has ACP support. It "kinda" works with the current version of Opencode, but every message displays an error in the console.

Here is how you can set it up:

1. create a config file (in case it doesn't exist already) at ~/.config/opencode/opencode.json
2. put there the following content:

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "auggie_acp": {
      "npm": "@mcpc-tech/acp-ai-provider",
      "name": "Auggie (ACP)",
      "options": {
        "command": "auggie",
        "args": [
            "--acp"
        ],
        "session": {
          "cwd": ".",
          "mcpServers": []
        }
      },
      "models": {
        "claude-sonnet-4-5": { "name": "Sonnet 4.5" }
      }
    }
  }
}

3. start opencode, enter /models, pick "Sonnet 4.5" in the Auggie (ACP) section.
4. send a ping message and see the model response and the error messages on your terminal

BTW, I used auggie ACP in PhpStorm, and it works fine with no errors, I believe it might be some internal problem in the Opencode–ACP integration.

Just in case, there was a PR for adding ACP backend support: #5095 that was discounted
