greenlight-review

Review a pytorch/pytorch pull request's changes and decide whether they are safe to land. Emits a single machine-readable verdict (LAND or NO_LAND) for the greenlight auto-land gate.

vllm-pytorch-ci-triage

Root-cause a vLLM torch-nightly CI regression report. Reads the pre-fetched, ANSI-stripped cluster logs from the triage artifact, identifies the real exception per regressed cluster, groups clusters by shared root cause, routes each cause to pytorch/pytorch,…

vllm-upstream-dedup

Review vLLM-routed torch-nightly root causes against existing upstream vLLM issues using read-only search results, and emit a validated upstream-checks artifact for the filer. Use in the vLLM torch-nightly triage workflow after root-cause analysis.

pytorch-clickhouse

Load this FIRST whenever working with PyTorch CI data (any pytorch/* org repo), the torchci/HUD codebase, or the PyTorch HUD ClickHouse database. Covers the two MCP servers that reach this data — pytorch-hud (curated no-SQL triage plus ~145 pre-tuned named…

ci-metrics

Fallback loader for the canonical PyTorch ci-metrics skill. Use for CI duration, failures, queue times, workflow trends, runner health, or dashboard data only when the canonical instructions are not already loaded and no accessible pytorch/pytorch checkout…

release-cherry-pick-missing-reverts

Find reverts that landed on pytorch/pytorch main but are missing from a release branch (release/X.Y) because the reverted commit was already shipped in a release candidate, and open one cherry-pick PR per missing revert against the release branch (on a fork…

release-update-docker-image-pin

Pin (or re-pin) the Linux manywheel builder docker images used by the nightly/release binary build workflows in pytorch/pytorch to a fixed .ci/docker build. Takes the release version (e.g. 2.13) as input. Updates DOCKER_IMAGE_PIN in…

release-create-tracker-issue

Generate (and optionally open) a PyTorch release tracker / cherry-pick tracking issue from a release announcement, like https://github.com/pytorch/pytorch/issues/180506. Triggered by mentions of "release tracker", "release tracking issue", "cherry-pick…

release-create-validation-issue

Generate a PyTorch release validation checklist issue by pulling open/closed issues from a GitHub milestone and cherry-picks from a release tracker issue. Triggered by mentions of "validation issue", "validation checklist", "release validation", or "release…

migrate-workflow-ec2-to-osdc

Step-by-step playbook for migrating a pytorch/pytorch .github/workflows/*.yml from EC2 to OSDC (ARC) runners — covers both dial-up and 100% opt-in patterns, with the inputs that must be plumbed through _linux-build.yml / _linux-test.yml. Use when migrating a…

release-go-live-binary-build-matrix

Update tools/scripts/generate_binary_build_matrix.py when a PyTorch release goes live. Advances CURRENT_STABLE_VERSION to the new stable, promotes the release-channel CUDA/ROCm arches to match the candidate/test channel, and regenerates the JSON test…

r2-outage-toggle

Disable or re-enable Cloudflare R2 (download-r2.pytorch.org) usage in manage_v2.py during R2 outages. Can toggle R2 off/on for nightly builds, prod/stable builds, or both. The affected packages are PT_FOUNDATION_PACKAGES (torch, torchvision, torchaudio,…
