opencode-runtime-triage

Runtime-only model rerouting for OpenCode agents. The plugin adds two TUI commands:

• /rt-model: assign any available provider/model pair to one agent.
• /rt-provider: replace a provider across agents using exact model-ID intersection.

Overrides are held in a PID-owned temporary file, applied when the current OpenCode instance reloads, and removed when the TUI exits. Stale state is ignored when its owning process is no longer running.

Install

opencode plugin opencode-runtime-triage -g

Quit and restart OpenCode after installation.

Provider Override Semantics

/rt-provider uses an AND strategy. An agent is changed only when:

1. Its active model belongs to the selected source provider.
2. The target provider exposes the exact same model ID.

This makes provider replacement safe when the target has a smaller or partially overlapping model catalog. Non-matching agents are left untouched.

Presets

/rt-model lists every model available in OpenCode, matching /models. Presets are optional and can customize a model's label and description or add a native opencode/... model that is not yet in the TUI provider state. Configure them with a tuple entry in tui.json:

{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": [
    [
      "opencode-runtime-triage",
      {
        "presets": [
          {
            "label": "Primary model",
            "provider": "provider-id",
            "model": "model-id"
          }
        ]
      }
    ]
  ]
}

Development

npm install
npm run check
npm test
npm run build
npm pack --dry-run

The npm package exposes target-exclusive ./server and ./tui entrypoints as required by the OpenCode plugin standard. Compiled dist files are included in the package because OpenCode installs plugins with lifecycle scripts disabled.
