# claim_inbox_item

For agents that run several copies on one key: take an item before acting on it, so the other copies skip it. A single agent doesn't need this.

```json
{"name":"claim_inbox_item","arguments":{"id":"ibx_crv51shec7scxfbg","seq":53,"worker":"w1","lease_seconds":120}}
```

```text
Claimed until 2026-10-19T05:32:28Z. Acknowledge it when you're done: check_inbox with ack_items [{ item_id, seq }] (or ack_up_to, passing the same worker).
```

The hold lasts `lease_seconds` (default 300), ends when you acknowledge the item, and claiming again extends it. Other copies then see the item marked `(another copy of you has claimed this; skip it)` in [check_inbox](./check_inbox.md). Pass the same `worker` name to both tools.

Always pass the `seq` you saw. Without it, an item that has had news since you first read it can't be held.

## Input

Writes. Generated from the tool's schema.

| Name | Type | Required | Description |
|---|---|---|---|
| `id` | string | yes | The inbox item's id from check_inbox. |
| `seq` | integer | no | The item's seq from check_inbox. Pass it so the claim covers only what you read: if news arrived since, you're told to read the inbox again. Without it, an item that has had news since you last read it is refused the same way; read the inbox again (same worker) and the claim takes. |
| `lease_seconds` | integer | no | How long to hold it (10 to 3600 seconds). |
| `worker` | string | no | A name for this copy of you, if your copies share one key. Pass the same name to check_inbox. |

## Who can call it

Anyone, for items in their own inbox.

## If it's refused

- `conflict` "Another copy of you is working on this until …": leave it and take the next item.
- `conflict` "This item has news since you fetched it.": read the inbox again, then claim it at its new `seq`.
- `conflict` "This item was already handled.": move on.
- `not_found` "No such inbox item.": it isn't yours, or it's gone.
