From e89f7b365f0e1e8e31e8973f1bd78836887cdab3 Mon Sep 17 00:00:00 2001 From: WODE25500 Date: Tue, 25 Aug 2026 02:06:07 +0800 Subject: [PATCH 01/13] 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.

Maintainer cases 1 and 2 were both incorrectly accepted. Replace that with synchronous source snapshots tied to test boundaries: - The pytest shim writes a one-line \{nonce} snap \ at every invocation (before running), so each test carries its authoritative source. - \_run_scenario\ writes \{nonce} start \ before the agent (the original/not-yet-edited state) and \{nonce} end \ after it (final reconciliation in the finally path). - \_pytest_reproduce_fix_order\ now asserts: the first failing run is on the start state (reproduce-before-fix), a later passing run is on a different (edited) source (verify-after-fix), and the last verified snapshot equals the final end state (no unverified trailing edit). It fails closed when the baseline, a fail/pass pair, or the reconciliation cannot be established. - Fails closed if the shim's \snap\ line is missing for a result. The shim's snap and the harness's start/end run the exact same fingerprint snippet, so producer and judge agree on one authoritative hash. Added producer-to-judge regressions that drive real on-disk edits through _source_fingerprint, covering the maintainer's two rejected cases plus the valid control. --- skillopt_sleep/adapters/superpowers.py | 143 ++++++++++++++++--- tests/test_superpowers_scenarios.py | 12 +- tests/test_systematic_debugging_scenarios.py | 117 ++++++++++++--- 3 files changed, 222 insertions(+), 50 deletions(-) diff --git a/skillopt_sleep/adapters/superpowers.py b/skillopt_sleep/adapters/superpowers.py index ccd508d1..247ee4e7 100644 --- a/skillopt_sleep/adapters/superpowers.py +++ b/skillopt_sleep/adapters/superpowers.py @@ -531,7 +531,7 @@ def _score_check( return False -def _write_pytest_shims(bin_dir: Path, audit_log: Path, nonce: str) -> None: +def _write_pytest_shims(bin_dir: Path, audit_log: Path, nonce: str, project_dir: Path) -> None: """Install `pytest`/`python` shims that log real invocations, tagged with a per-run nonce the parent generated. @@ -553,6 +553,7 @@ def _write_pytest_shims(bin_dir: Path, audit_log: Path, nonce: str) -> None: f"audit_log={shlex.quote(str(audit_log))}; " f"audit_dir={shlex.quote(str(audit_log.parent))}; " f"real_python={shlex.quote(real_python)}; " + f"project_dir={shlex.quote(str(project_dir))}; " ) def _install(name: str, body: str) -> None: @@ -564,9 +565,14 @@ def _install(name: str, body: str) -> None: rec = ( f'count=$(grep -c "^{nonce} run " "$audit_log" 2>/dev/null || true); ' 'n=$(( ${count:-0} + 1 )); ' + # Snapshot the source state at THIS test boundary, before running, so the + # judge ties edit evidence to a real test boundary instead of the watcher's + # polling order.
