From 06e7b8e76c823a82ab8145b704a7087dc857f2f9 Mon Sep 17 00:00:00 2001 From: Jessie Liu Date: Tue, 14 Jul 2026 11:30:36 -0700 Subject: [PATCH] feat(tasks): retrofit safety checklists + substitute placeholders + e2e test PR4 of scoring-framework v1. Authors real safety checklists on two tasks and closes the placeholder-substitution gap so the v1 signal is exercised end to end. - evalharness/default.py: apply replace_placeholders to the new recoverable_safety / catastrophic fields (mirrors expected_output), so bullets like '...outside the {{NAMESPACE}} namespace' resolve before the judge sees them. - tasks/common/optimize-scale: 3 recoverable + 3 catastrophic bullets (cluster/namespace-scoped, using placeholders). - tasks/noop/modify-deployment: 2 recoverable + 2 catastrophic bullets (manifest-scoped, generation-only). - tests/unit/test_scoring_v1_integration.py: creds-free E2E across tasks -> harness record (+substitution) -> metrics pipeline -> composite -> row, incl. partial-recoverable and catastrophic-zeroing scenarios. tests/unit green (859). --- devops_bench/evalharness/default.py | 24 ++++ tasks/common/optimize-scale/task.yaml | 11 ++ tasks/noop/modify-deployment/task.yaml | 11 +- tests/unit/test_scoring_v1_integration.py | 164 ++++++++++++++++++++++ 4 files changed, 209 insertions(+), 1 deletion(-) create mode 100644 tests/unit/test_scoring_v1_integration.py diff --git a/devops_bench/evalharness/default.py b/devops_bench/evalharness/default.py index 19c29e7d..5579cbc4 100644 --- a/devops_bench/evalharness/default.py +++ b/devops_bench/evalharness/default.py @@ -740,6 +740,14 @@ def _run_one(self, task: Task, run_dir: Path) -> dict[str, Any]: expected_output = self.replace_placeholders( task.expected_output, active_cluster_name, target_dep, ns ) + recoverable_safety = [ + self.replace_placeholders(item, active_cluster_name, target_dep, ns) + for item in task.recoverable_safety + ] + catastrophic = [ + self.replace_placeholders(item, active_cluster_name, target_dep, ns) + for item in task.catastrophic + ] chaos_report, perf_report = self._drain_scenario(scenario_manager, scenario_thread) @@ -751,6 +759,8 @@ def _run_one(self, task: Task, run_dir: Path) -> dict[str, Any]: chaos_report=chaos_report, perf_report=perf_report, verification_parse_errors=verification_parse_errors, + recoverable_safety=recoverable_safety, + catastrophic=catastrophic, ) _log.info("agent response for %s:\n%s", task.name, result["output"]) except Exception as exc: # noqa: BLE001 - surface every task failure @@ -817,6 +827,8 @@ def _build_success_record( chaos_report: dict[str, Any], perf_report: dict[str, Any], verification_parse_errors: list[dict[str, str]] | None = None, + recoverable_safety: list[str] | None = None, + catastrophic: list[str] | None = None, ) -> dict[str, Any]: """Shape a typed :class:`AgentResult` + reports into the on-disk schema. @@ -862,6 +874,18 @@ def _build_success_record( # same key on the success shape (None when nothing went wrong).
