From 5a4c94290d3ff21db03b72d184309776e5f4b5b2 Mon Sep 17 00:00:00 2001 From: Mason Daugherty <61371264+mdrxy@users.noreply.github.com> Date: Wed, 1 Jul 2026 18:51:03 +0000 Subject: [PATCH 1/5] feat(evals): goal-tool over-eager-calling evals + gated prompt copy `dcode`'s goal-tools prompt made models call `get_rubric`/`get_goal` even when no goal or rubric was ever set. Add a `tool_not_called` hard-fail assertion and a `test_goal_tools.py` eval module (baseline gates that the tools stay untouched with no goal/rubric set, plus a hillclimb case that a consulted rubric is still allowed), and rewrite `GOAL_TOOLS_SYSTEM_PROMPT` to lead with the precondition that the tools are inert when nothing is set.
