Caching
Can I share a cache between workflows?
Quick answer
On GitHub-hosted runners, only within the same repository and branch scope. runnerhut caches are shared across workflows in the organisation.
The detail that matters
Cross-workflow sharing matters most when build and test are separate workflows that would otherwise each pay for their own cold cache.

Start free. Migrating away is the same one line, and we publish that diff too.
