From 0c714857ce94fd76c628649bf3736ef3027c4e1c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Amaury=20Lev=C3=A9?= Date: Wed, 17 Jun 2026 17:42:37 +0200 Subject: [PATCH 1/6] Fix test-anti-patterns skill activation for 5 evals Sibling skills with overlapping descriptions were stealing activation from test-anti-patterns in plugin eval runs (coverage-analysis, assertion-quality, test-smell-detection). Reword descriptions so test-anti-patterns owns the umbrella 'audit my tests for anti-patterns' severity-ranked report, and add DO NOT USE redirects in the metric-focused siblings. Kept all descriptions within the 1024-char cap.
