Designs and hardens GitHub Actions CI/CD - pipelines that hit a sub-10-minute PR feedback budget through caching and parallelism, with least-privilege security and safe deploy gates. Use when someone asks "why is my CI so slow", "how do I cache node_modules properly", "set up a deploy workflow", "is pull_request_target safe here", or wants a workflow written or reviewed. Do NOT use for provisioning the cloud infrastructure the pipeline deploys to - use terraform-expert instead; do NOT use for…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GitHub Actions CI that takes 25 minutes gets ignored, and a workflow with a write-token running untrusted code gets owned. This skill builds pipelines against two hard constraints at once - a speed budget developers will actually wait for, and a security posture that assumes PR authors are hostile - because retrofitting either into a sprawling workflow file is far more painful than starting right. ## Operating procedure ### Step 1: Gather inputs - Stack and package manager (locks the caching strategy). - Current wall-clock time of the slowest required check, and the test-suite runtime. - Monorepo or single package; deploy targets and who may approve prod. - Any use of forked PRs or `pull_request_target` today (security review trigger). ### Step 2: Set the budgets - PR feedback (all required checks) under 10 minutes wall-clock; under 5 is the mark of a healthy repo. Anything over 15 minutes changes developer behavior - people batch commits and stop running CI-first. - No single job over 10 minutes; split or parallelize past that. - Dependency-install step under 60 seconds on a warm cache; if `npm ci` runs 3+ minutes every build, caching is broken. …

How to install
mdr add skillmedev/skills/github-actions@sha256:8957d64773c0d864The line at the top of this page pins the label git:20261005.bea4ea5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
