dsh-opencode-go

You already have an OpenCode Go subscription and want to call its models directly inside DeepSeek Harness, but DSH does not ship that routing out of the box. dsh-opencode-go is a lightweight adapter built for exactly this: install the plugin, paste your API key, and session headers, model catalog, and plan-usage display are all handled automatically — no DSH source changes required, truly one key to start.

The plugin spans four core scenarios: streaming output, tool calls, image input, and a Web settings page. Every request carries the Harness User-Agent and x-opencode-session headers with a stable per-session ID; the model list is fetched live from the gateway and synced with models.dev online configuration, so newly listed models appear after a refresh without any plugin upgrade. Protocol execution is delegated to pi-ai, and the plugin itself injects no hidden system prompts, keeping behaviour transparent.

If you hold an OpenCode Go subscription and want the least-friction path into DSH for either your Web or Headless workflow, this plugin removes the boilerplate of manual routing setup, header maintenance, and multi-protocol tracking — so you can focus on the task at hand.
