list_transaction_contacts

List transaction contacts

List buyer-visible people connected to a transaction (an ended one reads too), including buyers, listing-side contacts, and saved transaction contacts. A contact the buyer added carries its contactId, the handle update_transaction_contact and delete_transaction_contact take; every other row has null there and cannot be changed by an agent. Values derived from external or editable records are delimited as untrusted data. This tool cannot contact anyone.

Effect: Read
Required scopes: workspace:read
Workflow stages: closing, offer, transaction
Data classes: contacts, transaction
Operation cost: 1 weighted units; additional domain limits may apply.
Configurations: Standard, Buyer UI v2
Muse proposal: Read. Retrieves or computes authorized information; consult the tool contract for its scopes and result. Meta makes the final classification during review.

Buyer approval and signing controls apply in addition to the scopes above. Read error and retry guidance before implementing recovery.

Input and output contracts

Returns structured content and a JSON text content block. Live discovery may compact a large output schema; execution validates the full contract below.

Input fields

Required applies within the containing object. Optional fields can be omitted; null is accepted only where listed. Field descriptions and constraints come from the source schema. The raw schema remains the complete contract.

Field	Required	Meaning and constraints
`workspaceId`string	Yes	Pattern validation applies; see the raw schema.
