The GitHub Actions knowledge system
Make GitHub Actions fast, cheap, and safe
20 public rules, each with a page that says how to detect the problem, how to fix it, and how to verify the fix: readable by you, fetchable by your coding agent, and applied automatically by StarSling.
How StarSling worksStart here
- The rule catalog
GitHub Actions optimizations
Every CI rule StarSling checks: performance, reliability, cost, and security, each with detection steps, the fix, and an agent prompt.
- The practice guides
GitHub Actions best practices
Eighteen reference guides on what good CI looks like: caching, sharding, trigger scope, runners, and workflow security, with real-world exemplars.
- Workflow patterns
docker/build-push-action, copy-paste ready
A complete Docker build-and-push workflow with layer caching, explained line by line.
- Workflow patterns
Docker CI on GitHub Actions, end to end
Building, testing, and shipping images from CI: the whole pipeline in one page.
For coding agents
The whole catalog is one fetch: /github-actions/catalog.json lists every rule with its stable ci.* id, category, detection mode, and page URLs. Every page on this site also serves a plain .md version for agents, listed in /llms.txt.
