Notification Templates

Notifications are template fills, not creative writing. Do not spawn a subagent for this. Fill the slots from data you already have, then append the result to the outbox.

Low-stock Slack alert

:warning: *Low stock* — {{sku}} ({{product_name}})
On hand: {{on_hand}} · Reorder point: {{reorder_point}} · Days of cover: {{days_cover}}
{{action_line}}

action_line is either PO {{po_id}} placed for {{qty}} units (ETA {{eta}}) or Awaiting review — {{reason}}.

Supplier email

Subject: PO {{po_id}} — {{qty}} × {{sku}}

Hi {{supplier_name}},

Please confirm PO {{po_id}} for {{qty}} units of {{sku}} ({{product_name}}) at ${{unit_price}}/unit.
Requested delivery: {{requested_date}}. {{expedite_note}}

Thanks,
StockPilot

Escalation (human review needed)

Routing (who gets what)

When you escalate beyond the default channel, add one line saying which threshold was crossed.

Batch, don't spam

For sweeps and daily checks, send one summary notification, not one per SKU. The low-stock template above is for a single-SKU task; for a sweep, compose a single message listing the actioned SKUs (and any deferred) and send it once at the end.

When the task explicitly asks for one alert per SKU (e.g. "send a personalized alert for each of the top 10"): fill the template once per SKU and write all lines to the outbox in one Bash heredoc, like:

Do not call send_slack_alert (or any subagent) once per SKU — that's N model round-trips for template-filling.

After sending a batch, your final response should be a brief confirmation ("✓ 10 alerts sent to ops — see outbox") plus a compact table of SKU + on-hand

• days-of-cover. Do not echo the full alert text in your reply; it's already in the outbox.

How to send

Append directly to /mnt/user/sinks/outbox.jsonl via Bash — one JSON object per line, e.g.:

Use json.dumps so newlines in the message are escaped (raw echo would break the JSONL). That's the whole job: one read for the data you need (if you don't have it), one append. If you're making more than two calls to send a notification, you've over-engineered it.
