/** |

* The two tools that change something. |
| 20 |
* |
| 21 |
* `create-booking` stands alone because its parameter shape — attendee details, |
| 22 |
* custom fields, guests, location — shares nothing with the others. Everything |
| 23 |
* that acts on a booking that already exists goes through `manage-booking` |
| 24 |
* behind an `action` enum, which is where Cal.com spends six separate tools. |
| 25 |
* |
| 26 |
* Destructive actions will not execute without a confirm_token minted by a dry |
| 27 |
* run. The token is bound to BOTH a fingerprint of the booking's current state |
| 28 |
* — so a booking that moved while the agent was thinking cannot be acted on |
| 29 |
* with stale numbers — AND a digest of the parameters that were previewed, so |
| 30 |
* the change that executes is the change a human approved. Reversible actions |
| 31 |
* (complete, no_show, resend_email, and update_details on anything but the |
| 32 |
* email address) execute directly. |
| 33 |
* |
| 34 |
* "Destructive" is decided per call rather than per action name, because two of |
| 35 |
* them are only destructive sometimes. See needsConfirmation(). |
| 36 |
* |
| 37 |
* @see \FluentBooking\App\Modules\MCP\Support\WriteGuard for the contract. |
