Request

Property	Type	Required	Description
location	object	Yes	An exact expression, complete statement or contiguous statement range to analyze.
symbolsPerCategoryLimit	integer | null	No	Maximum number of symbols to return in each data-flow category.
expectedSnapshot	object | null	No	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	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.

Bounded collections and continuation

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

• $/oneOf/0/properties/data/properties/variablesDeclared
• $/oneOf/0/properties/data/properties/readInside
• $/oneOf/0/properties/data/properties/writtenInside
• $/oneOf/0/properties/data/properties/dataFlowsIn
• $/oneOf/0/properties/data/properties/dataFlowsOut
• $/oneOf/0/properties/data/properties/captured

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
