Github Actions

This gives Claude the knowledge to set up and troubleshoot GitHub Actions workflows without hunting through docs. It covers the full syntax: triggers (push, PR, cron, manual), job dependencies, matrix builds across Node/Python/OS combinations, secrets handling, and contexts for accessing runtime data. The progressive disclosure is smart here since CI/CD configs can sprawl. You get enough in the quick start to wire up a basic test run, then the full reference when you need to debug why your workflow only runs on some branches or figure out how to pass outputs between jobs. Solid for teams standardizing on Actions or migrating from Jenkins/CircleCI.
