Docs: record where CI is configured in AGENTS.md - #7236
Merged
Conversation
WarpX splits its CI across two systems, and the split is not obvious: `.github/workflows/` holds the build-only jobs, while `.azure-pipelines.yml` builds the dimensionality/feature matrix and runs the actual `ctest` suite. The consequence worth writing down is that the Azure matrix carries the `WARPX_CMAKE_FLAGS` that decide which optional subsystems get compiled at all -- `WarpX_PETSC=ON`, for instance, is set there for the 1D, 2D and RZ jobs and nowhere in `.github/workflows/`. Looking at only one of the two locations makes it easy to wrongly conclude that an `#ifdef`-guarded code path has no coverage. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

GPU tests live in a third place: `.gitlab/ci.yaml`, run on the HPSF Frank cluster through a GitHub-to-GitLab mirror rather than as a GitHub Actions workflow. Every `runs-on:` in `.github/workflows/` is a stock GitHub-hosted image, so `cuda.yml` / `hip.yml` / `intel.yml` only compile; nothing there executes on a GPU. Worth noting that it is label-gated (`bot: run GPU`), so it does not appear in a default PR's checks. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

In several conversations with Claude Opus 5, I have noticed that it seems to accidentally overlook
.azure-pipelines.yml. For instance:This PR updates the
AGENTS.mdto prevent this error from recurring.
