somehow github actions kinda suck - api is very limited: there's no way really to download a cache entry via api artifacts api doesn't provide a way to find artifacts by name "create workflow dispatch event" doesn't fucking return the created run's id - you cant use matrix within composite actions, you need to do that wherever you use the composite action - caches are very half-assed and again introduce too much boilerplate ended up just making an incredible crutch to invoke another workflow from a workflow via api and waiting for it to finish, and then manually download its artifacts. this way i can save up to 2-5 minutes on each run
