@toninho09/opencode-wakeup

Schedule a future prompt back into the current opencode session.

Use wakeup_after or wakeup_at to tell opencode to wake itself up after a delay or at a specific time. When the timer fires the plugin sends a prompt back into the same session, so opencode can resume work — checking a deploy, retrying a build, polling an external process, or anything else that needs a future nudge.

Install

npm install @toninho09/opencode-wakeup

Add the server plugin to opencode.json (or opencode.jsonc):

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["@toninho09/opencode-wakeup"]
}

For the Wakeups sidebar panel, also add the TUI plugin to tui.json (or tui.jsonc):

{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": ["@toninho09/opencode-wakeup"]
}

Restart opencode after editing either config file.

Note If you only configure opencode.json the tools work but the sidebar panel is not shown. If you only configure tui.json the sidebar loads but nothing schedules or fires wakeups. Configure both for the full experience.

What you get

• Four scheduling tools available to the model: wakeup_after, wakeup_at, wakeup_list, wakeup_cancel
• A Wakeups panel in the session sidebar (requires TUI plugin)
• Countdown display with target time, short ID, and message preview
• Wakeups survive an opencode restart — pending timers are rehydrated automatically
• Multiple concurrent opencode instances are safe; each instance owns its own session files

Tools

wakeup_after

Schedule a wakeup relative to now.

| Argument | Type | Required | Description | |---|---|---|---| | seconds | number | yes | Delay from now in seconds | | message | string | no | Prompt to send when the wakeup fires |

Returns JSON with status, id, sessionID, runAt, delaySeconds, and message.

wakeup_at

Schedule a wakeup at a specific date/time.

| Argument | Type | Required | Description | |---|---|---|---| | datetime | string | yes | Target date/time. Prefer ISO 8601 (e.g. 2026-06-10T15:30:00-03:00) | | message | string | no | Prompt to send when the wakeup fires |

Bare ISO dates such as 2026-06-10 are interpreted as local midnight, not UTC midnight. The datetime must be in the future. Invalid or past dates are rejected.

Returns the same shape as wakeup_after.

wakeup_list

List currently scheduled wakeups.

| Argument | Type | Required | Description | |---|---|---|---| | allSessions | boolean | no | When true, list wakeups across all sessions this plugin instance knows about |

By default only wakeups for the current session are returned. Triggered, cancelled, and failed wakeups are excluded.

Returns { "count": number, "wakeups": [...] }.

wakeup_cancel

Cancel a pending wakeup.

| Argument | Type | Required | Description | |---|---|---|---| | id | string | yes | Wakeup ID returned by a scheduling tool |

Cancelling an unknown or already-fired wakeup returns status: "not_found".

Return format

Scheduling and listing return wakeup objects in this shape:

{
  "status": "scheduled",
  "id": "wakeup_...",
  "sessionID": "...",
  "runAt": "2026-06-10T18:30:00.000Z",
  "delaySeconds": 60,
  "message": "Check the deploy"
}

wakeup_list wraps results in:

{
  "count": 1,
  "wakeups": [...]
}

TUI sidebar panel

The TUI plugin registers a Wakeups panel in the session sidebar. It polls the active session's state file every second and shows:

• Countdown to each scheduled wakeup
• Target date/time
• Short wakeup ID
• Message preview

No wakeup data appears in the sidebar if no wakeups are currently scheduled for the session.

How it works

Wakeups are persisted to a per-session JSON file under the system temp directory. This means:

• Restart recovery — when opencode restarts the server plugin rehydrates scheduled wakeups the first time it sees a session. Future wakeups are re-armed; already-overdue wakeups fire promptly.
• Multi-instance safe — each opencode instance fully owns its session files. Concurrent instances can never read or overwrite each other's wakeups.
• No database — the only runtime state is the per-session JSON file; nothing to set up.

When a wakeup fires, the plugin calls client.session.prompt(...) with the configured message so opencode actually resumes the session.

Long delays (beyond ~24 days) are handled by re-arming timers in chunks, so wakeup_at works for any future date supported by JavaScript's Date.

Manual / local setup

To use the local package path instead of the npm package, build first:

bun install
bun run build

Then reference the local path in your config files:

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["./path/to/opencode-wakeup"]
}

{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": ["./path/to/opencode-wakeup"]
}

Development

bun install
bun run typecheck
bun run build
bun run test
npm pack --dry-run

The package ships dist/index.js for the server plugin and dist/tui.tsx for the TUI plugin. Shipping the TSX source is intentional — the OpenTUI runtime loads it with the required TSX transform support.
