The first round of this PR removed SKIP_WIN32, fixed venv_py to use Scripts/python.exe, and added Lib/site-packages to the consumer glob — all necessary. Windows verification (Win11 ARM64, Py 3.13, Git Bash) showed two more blockers, both addressed here. 1. Pip dependency resolver picks unbuildable cryptography on ARM64. Without --prefer-binary, pip picks a cryptography version with no published ARM64 wheel and tries to build it from source. That needs Rust/Cargo, almost never present on user machines → BUILD_FAILED with err_kind=other:cryptography. A binary wheel exists for an adjacent version (cryptography-46.0.3-cp311-abi3-win_arm64.whl); --prefer-binary tells pip to pick it. Cross-platform safe (no-op where the latest version already has a wheel). 2. pywin32 .pth files aren't processed by sys.path.insert(). With the venv built, ensure_agent_sdk.py's post-build probe passes (it runs from venv_py, where Python's site.py at startup processes pywin32.pth and registers win32/, win32/lib/ plus runs pywin32_bootstrap.py to set the DLL search dir). But llm.py runs in the hook's SYSTEM Python and adds the venv via sys.path.insert(), which doesn't trigger site.py at all. Without the bootstrap, the SDK's mcp.client.stdio → mcp.os.win32.utilities chain raises ModuleNotFoundError: pywintypes and the agentic reviewer falls back to single-shot silently — exactly the symptom this PR is trying to fix. The probe says NOOP_VENV; the actual consumer fails. Probe and consumer use different Pythons. Replicate what site.py would do: after inserting site-packages, also insert win32/ and win32/lib/, then exec pywin32_bootstrap.py. Pulled into a shared helper _inject_agent_sdk_venv_into_syspath() so both consumer sites (3P SDK fallback, agentic_review fallback) call the same code — Windows handling stays in one place. Verified on macOS (POSIX path unchanged): - Helper end-to-end test: POSIX-layout venv detected + fake package imports successfully via the injected path - Windows-layout venv also detected; win32 branch correctly skipped via sys.platform check - Both files pass py_compile Credit: @mhegazy verified the previous commit on Win11 ARM64 / Py 3.13 / Git Bash, surfaced both issues end-to-end, and provided the exact fix patterns. This commit applies them with the pywin32 part factored into a shared helper (vs. inlining at both consumer sites). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
