opencode-elapsed-plugin

opencode-elapsed-plugin is a small OpenCode TUI-only plugin that mounts in the session_prompt_right slot and shows three prompt-side indicators:

• current session status (idle, busy, or retry)
• cmd elapsed time since the latest user message
• agent elapsed time since the latest completed assistant message

The v1 implementation keeps the logic intentionally simple: every second it recomputes the latest timestamps from api.state.session.messages(sessionID) instead of maintaining a mutable cache.

Use in OpenCode

Global config

Add the package name to your global OpenCode plugin config:

{
  "plugin": [
    "opencode-elapsed-plugin"
  ]
}

Then restart OpenCode.

Per-project config

If you want to enable it only for one project, add the same package name to that project's OpenCode config:

{
  "plugin": [
    "opencode-elapsed-plugin"
  ]
}

Then restart OpenCode inside that project.

Install from the OpenCode settings UI

If you are using the settings screen:

1. Open OpenCode settings
2. Go to the plugin install/add section
3. Paste opencode-elapsed-plugin
4. Save or install
5. Restart OpenCode

What you should see

• idle, busy, or retry status in the prompt area
• cmd timer for the latest user message
• agent timer for the latest completed assistant response

Reinstall or refresh

If OpenCode keeps using an older cached version, remove the cached package and restart OpenCode:

rm -rf ~/.cache/opencode/packages/opencode-elapsed-plugin@latest

If needed, remove all cached versions:

rm -rf ~/.cache/opencode/packages/opencode-elapsed-plugin@*

Then start OpenCode again.

Local plugin path

If you want to load the plugin from a local folder instead of npm, point OpenCode at the folder path:

{
  "plugin": [
    "file:/absolute/path/to/opencode-elapsed-plugin"
  ]
}

Package contract

The package is intentionally TUI-only. It exposes only exports["./tui"], and that entry points to raw tui.tsx source so OpenCode can compile it directly instead of loading prebuilt JS through @opentui/solid/jsx-runtime.

That TUI entry default-exports an OpenCode plugin module with this shape:

{
  id: "opencode-elapsed-plugin",
  tui: async (api) => {
    // register session_prompt_right slot renderer
  },
}

There is no server plugin in v1.
