Add an open home to a property with date, times, a primary agent and optional secondary agents.

VaultRE API: https://cotlet.dev/docs/api/vaultre.md

`POST https://cotlet.dev/api/v1/vaultre/properties/{property_id}/open-homes`

Access: write. Confirm: waits for the user's OK before it runs.

Does what Add Open Home on the property card does. Vault adds the event to the calendars of the agents named. Editing or removing an open home is done in Vault. By default you confirm each call; you can switch that off for this tool.

|---|---|---|---|
| `property_id` | string | yes | Property ID from search_properties. |
| `date` | date | yes | Date of the open home. |
| `start_time` | string | yes | Start time, e.g. '10:00'. |
| `end_time` | string | yes | End time, e.g. '10:30'. |
| `primary_agent` | string | yes | Email of the agent running the open home. |
| `secondary_agents` | array | no | Emails of additional agents. |

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
