Make a GitHub Actions workflow faster, cheaper, and harder to attack — by profiling where wall-clock and billed minutes actually go, then adding content-keyed caching, matrix/job parallelism, run-cancellation, and path filters, and hardening the supply chain (SHA-pinned actions, least-privilege GITHUB_TOKEN, safe fork-PR handling). Use when CI is slow or queues, when a repo burns Actions minutes, or before trusting a workflow that runs on untrusted pull requests.

From the source SKILL.md

A workflow that takes 22 minutes and costs you a fortune in minutes is rarely slow for one reason — it's usually re-downloading dependencies every run, running serially what could run in parallel, and building branches no one is waiting on. And the same file is often a supply-chain liability: a third-party action pinned to @v3 can be repointed under you, and a write-all token plus pull_request_target is one malicious fork PR away from leaking secrets. This skill measures before it touches anything, then ships fixes ordered by payoff — biggest time or security win first — as concrete YAML…
