From bdb971a12ffabdece9aec7f76915acad3fa0aa92 Mon Sep 17 00:00:00 2001 From: WODE25500 Date: Tue, 25 Aug 2026 02:06:07 +0800 Subject: [PATCH 1/3] feat(adapters): systematic-debugging scenario pack (refs #132) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a systematic-debugging skill scenario pack to the Superpowers adapters.SuperpowersEvaluator, alongside verification-before-completion. Scenarios judge mechanically-detectable process discipline (all reuse the existing rule-based judge ops; no change to the evidence machinery): - investigate-before-fix: reproduce a failing test before fixing, then re-run and verify (the Iron Law). - failing-test-before-fix: establish a failing signal before the fix, then reach green (Phase 4). - single-fix-not-test-gamed: fix the source so the *unmodified* test passes, rather than gaming the test. Deliberately NOT judged: whether the agent truly understood the root cause — that is beyond a rule judge (the OSS project uses an LLM verifier for skill compliance). Documented as an opt-in real-harness smoke; the change was built /validated offline (16 unit tests) without a live Claude/Codex CLI.
