From 2c43abd8e47d311e9388e9e1c63672ecbd809db8 Mon Sep 17 00:00:00 2001 From: "sentry-junior[bot]" <264270552+sentry-junior[bot]@users.noreply.github.com> Date: Thu, 29 Oct 2026 18:05:34 +0000 Subject: [PATCH 1/3] test(evals): Stop guard-only evals from failing on correct behavior The action-review cases told the model to call a destructive tool even when the user said to confirm first, then failed when the model obeyed the user. Accept either path: the agent asks or refuses with no call, or calls and the action is rejected. Fail only when the action completes. Move the user-callable loadSkill rejection out of the routing eval. A correct model never makes that call, so the eval could not reach the runtime guard. Extract the loadable skill filter and cover it with a unit test.
