Routine Health Check

Purpose

Routines run unattended. When one of them starts erroring or running away on cost, the user needs to know — but only via the same channels they already check (the Inbox), not a separate alerting layer.

This skill turns "watch the other routines" into a routine itself. It loads into a daily fire of AssistantAgent and produces findings.

What you check

For each routine the user owns:

1. Error rate — count of routine_runs.outcome IN ('error', 'budget_exceeded') in the last 24h vs total runs in 24h. > 30% = high importance.
2. Drift — has the agent stopped emitting findings (no inbox_add calls for N consecutive runs)? That suggests the routine is silently doing nothing.
3. Cost spike — sum routine_runs.cost_usd over 24h vs the routine's daily cap. ≥ 80% = high importance.
4. Stuck runs — outcome='started' for > 1h means the run never finished cleanly.

What you produce

For each issue, call inbox_add with:

{
  "kind": "routine_health",
  "summary": "<routine name> — <one-line issue + action>",
  "importance": "<calibrate via score-importance skill>",
  "reasoning": "<the numbers backing the claim>",
  "suggestedAction": {
    "label": "Open routine",
    "link": "/dashboard/routines/<id>"
  },
  "tags": ["routine-health"],
  "relatedItemIds": ["<routineId>"]
}

Scope rules

• Don't emit findings for routines the user has explicitly disabled — they already chose to stop them.
• Don't emit a finding for routine-health itself (that's recursive — and you'd cause exactly the noise you're checking for).
• Don't emit duplicate findings — if you've reported this routine in the last 24h, skip unless the metric got materially worse.

Tone

Findings are read while the user is doing other things. Lead with the routine name + the actionable bit, never with technical detail. Detail goes in reasoning.

Examples:

• ✓ Stuck-tickets sweeper — 4 of 6 fires errored (Gmail token expired). Reconnect Gmail.
• ✗ routine_runs WHERE outcome='error' returned 4 rows for routine_id=abc...

When nothing's wrong

Don't emit anything. The Inbox already shows zero new items as "all clear". A "all routines healthy" finding once a day is what desensitises users to the channel.
