From 329288aeef882bd357969561075045d66b11959d Mon Sep 17 00:00:00 2001 From: wenjiefan Date: Fri, 10 Jul 2026 12:58:32 +0200 Subject: [PATCH 01/17] Add BC PR-Review engine arm with BCQuality ref override Lands the faithful convergence arm (engine adapter + BCQuality fetch/filter + review.json transform) and wires it into the CLI as 'bcbench evaluate engine'. The adapter accepts optional bcquality_repo/bcquality_ref that are passed to the engine's fetch via BCQUALITY_REPO/BCQUALITY_REF env vars, so a CI run can review against a modified BCQuality branch/SHA without editing the engine. --- src/bcbench/agent/__init__.py | 3 +- src/bcbench/agent/engine/__init__.py | 3 + src/bcbench/agent/engine/agent.py | 215 +++++++++++++++++++ src/bcbench/agent/engine/fetch_bcquality.ps1 | 41 ++++ src/bcbench/commands/evaluate.py | 63 +++++- 5 files changed, 323 insertions(+), 2 deletions(-) create mode 100644 src/bcbench/agent/engine/__init__.py create mode 100644 src/bcbench/agent/engine/agent.py create mode 100644 src/bcbench/agent/engine/fetch_bcquality.ps1 diff --git a/src/bcbench/agent/__init__.py b/src/bcbench/agent/__init__.py index ab30132d1..efd425de6 100644 --- a/src/bcbench/agent/__init__.py +++ b/src/bcbench/agent/__init__.py @@ -3,5 +3,6 @@ from bcbench.agent.bcal import BCalBackendConfig, run_bcal_agent from bcbench.agent.claude import run_claude_code from bcbench.agent.copilot import run_copilot_agent +from bcbench.agent.engine import run_engine_review -__all__ = ["BCalBackendConfig", "run_bcal_agent", "run_claude_code", "run_copilot_agent"] +__all__ = ["BCalBackendConfig", "run_bcal_agent", "run_claude_code", "run_copilot_agent", "run_engine_review"] diff --git a/src/bcbench/agent/engine/__init__.py b/src/bcbench/agent/engine/__init__.py new file mode 100644 index 000000000..bfc657ac6 --- /dev/null +++ b/src/bcbench/agent/engine/__init__.py @@ -0,0 +1,3 @@ +from bcbench.agent.engine.agent import run_engine_review + +__all__ = ["run_engine_review"] diff --git a/src/bcbench/agent/engine/agent.py b/src/bcbench/agent/engine/agent.py new file mode 100644 index 000000000..567cabead --- /dev/null +++ b/src/bcbench/agent/engine/agent.py @@ -0,0 +1,215 @@ +"""BC PR-Review engine agent runner (faithful convergence arm). + +Instead of BC-Bench's own review pipeline, this runner invokes the exact +production reviewer script (``Invoke-CopilotPRReview.ps1`` from +``microsoft/BC-ALReviewAgent``) in its local review mode against the +patched worktree, then normalizes the engine's ``al-code-review-findings.json`` +into the ``review.json`` shape BC-Bench's scorer already understands. +""" + +import json +import os +import shutil +import subprocess +import time +from pathlib import Path + +from bcbench.dataset import BaseDatasetEntry +from bcbench.exceptions import AgentError, AgentTimeoutError +from bcbench.logger import get_logger +from bcbench.types import AgentMetrics, ExperimentConfiguration + +logger = get_logger(__name__) + +FETCH_BCQUALITY_SCRIPT = Path(__file__).parent / "fetch_bcquality.ps1" +FINDINGS_FILE_NAME = "al-code-review-findings.json" +REVIEW_OUTPUT_FILE = "review.json" +_ENGINE_TIMEOUT_SECONDS = 1800 + + +def _pwsh() -> str: + pwsh = shutil.which("pwsh") + if not pwsh: + raise AgentError("pwsh (PowerShell 7+) is required to run the PR-review engine but was not found on PATH") + return pwsh + + +def _resolve_token(gh_token: str | None) -> str: + token = gh_token or os.environ.get("GH_TOKEN") or os.environ.get("GITHUB_TOKEN") + if token: + return token + gh = shutil.which("gh") + if gh: + result = subprocess.run([gh, "auth", "token"], capture_output=True, text=True, check=False) + if result.returncode == 0 and result.stdout.strip(): + return result.stdout.strip() + raise AgentError("No GitHub/Copilot token available.

Pin _DEFAULT_ENGINE_REF to a released tag (1.15.4) so BCQuality content is the only variable under test and runs stay reproducible; ENGINE_REF still overrides. Unify severity on the shared Severity.from_input table (minor -> Medium, matching the production engine's BCQualitySeverityMap floor) and delete engine.py's divergent _SEVERITY_MAP so every arm scores identically. Sanitize clone-only credentials (BCQUALITY_REPO_TOKEN/ENGINE_REPO_TOKEN) from the reviewer subprocess env; only GH_TOKEN auth remains.
