Find out whether an agent can actually choose correctly within a toolset
Find out whether an agent can actually choose correctly within a toolset. Reports pairs of tools whose words overlap enough to be confusable, descriptions too short or too empty to distinguish, undescribed arguments an agent must guess at, tools with so many arguments they are filled wrong, state-changing tools with no annotation hints, and the total size of the manifest, which occupies the model context on every turn.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
