Request

Property Type Required Description
expectedSnapshot object Yes Echo the snapshot returned with the data or transaction state used to construct this request.
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 No 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:

  • $/oneOf/1/properties/continuation

Examples

Commit the reviewed snapshot

Workflow: Stage, review and commit one change, step 4.

Write the staged files only when the transaction still matches the previewed snapshot.

Expected outcome: The commit succeeds only if the supplied snapshot still identifies the current staged revision.
