What
The artifact read_page_data action validates the requested schema against what the session actually offers and fails with a dedicated error code instead of attempting a lookup.
Details
The check runs before any lookup and throws its own error code on mismatch.
The tool description is generated with the concrete list of available schema names inlined, so the model sees valid options up front.
Evidence
read_page_data: the requested interaction schema is not available in this session.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
