Sets up act so you can run GitHub Actions workflows locally before pushing, which is exactly what you want if you're tired of using CI as your debugger. Drops two scripts into your repo (one to install act, one to run it without timing out) and adds instructions to AGENTS.md so Claude knows how to verify changes pass CI. The run script polls logs in the background instead of blocking, which matters for agent workflows. You'll need Docker running, and first pulls are slow (2GB+ images), but after that you get real CI feedback in minutes instead of waiting for remote runners. Honest take: this should probably be standard setup for any repo with non-trivial CI.
