Last Activity

OpenCode TUI plugin that shows a relative last-activity indicator in session_prompt_right so you can tell whether the current session is active, waiting, retrying, or possibly stalled.

Features

• shows active now while work is happening
• shows last activity 8s ago when the session is idle
• shows waiting on permission and waiting on question when input is blocked
• shows possibly stalled 2m ago when the session stays busy without recent activity
• optional inactivity-only mode that stays hidden until the session goes quiet
• optional compact mode for tighter prompt layouts

Install

Install the package with OpenCode:

opencode plugin @alexandroheredia/opencode-last-activity

Then quit and restart OpenCode.

Manual Config

If you prefer to edit tui.json directly:

{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": [
    [
      "@alexandroheredia/opencode-last-activity",
      {
        "compact": false,
        "activeWindowMs": 5000,
        "inactivityNoticeMs": 30000,
        "stalledWindowMs": 60000,
        "visibility": "always"
      }
    ]
  ]
}

Options

Option	Type	Default	Description
compact	boolean	false	Uses shorter labels such as active, 2m ago, and stalled 2m ago.
visibility	"always" | "inactivity-only"	"always"	Controls whether the indicator is always visible or only after inactivity.
activeWindowMs	number	5000	Age threshold that still counts as active.
inactivityNoticeMs	number	30000	In inactivity-only mode, how long to wait before showing quiet sessions.
stalledWindowMs	number	60000	Age threshold for switching a busy session to stalled.

If inactivityNoticeMs is set lower than activeWindowMs, the plugin raises it to match the active window. If stalledWindowMs is set lower than inactivityNoticeMs, the plugin pushes it above the inactivity threshold so labels stay sane.

Inactivity-Only Example

If you only want to see the indicator when OpenCode has gone quiet for a while:

{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": [
    [
      "@alexandroheredia/opencode-last-activity",
      {
        "visibility": "inactivity-only",
        "inactivityNoticeMs": 30000,
        "stalledWindowMs": 60000
      }
    ]
  ]
}

In this mode, active sessions stay hidden until there has been no output for at least inactivityNoticeMs. Permission prompts, questions, and retries still show immediately.

Label Examples

Full mode:

• active now
• last activity just now
• waiting on permission
• waiting on question
• retrying 12s ago
• possibly stalled 3m ago

Compact mode:

• active
• just now
• permission
• question
• retry 12s ago
• stalled 3m ago
