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.
warnings	array	No	Non-fatal warnings the agent should consider.

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.

diagnostics	object	Yes	Diagnostics that explain the failed invocation.
reporting	object	No	Error-reporting workflow available for an unhandled failure.

Bounded collections and continuation

These response locations publish returned items with explicit bounds and continuation state:

• $/oneOf/0/properties/data/properties/locations

Continuations and required actions

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

• $/oneOf/1/properties/continuation
