workspace object | null No Provide workspaceId, alias, path, or any combination.

Response

Success response

Property Type Required Description
ok boolean constant (true) Yes Whether the tool invocation succeeded.
data object | null Yes Tool-specific result payload.
snapshot object Yes Exact immutable workspace snapshot associated with the result, when available.

Error response

Property Type Required Description
ok boolean constant (false) Yes Whether the tool invocation succeeded.
error object Yes Structured error details when the invocation failed.
continuation oneOf No Action the agent should take before retrying or continuing.

Continuations and required actions

A non-success response may include a structured continuation at the following schema location. Follow its tool call or user-action instruction instead of guessing how to retry:
