What this server can do
41 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
rubrkit_add_golden_case(tags, input, origin, weight, criteria, originRef, expectedOutput, artifactBundleId)- Add a golden case (a real edge-case input with a confirmed-correct output) to an artifact bundle via POST /api/v1/artifact-bundles/{artifactBundleId}/golden-cases. Requires artifact_bundles:write for API keys. Required: artifactBundleId, input.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
