github-actions is agent-read markdown (skill) from openhands/extensions: Create, debug, and test GitHub Actions workflows and custom actions. Use when building CI/CD pipelines, automating workflows, or troubleshooting GitHub Actions..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

# GitHub Actions Guide
## Critical Rules
**Custom Action Deployment:**
- New custom actions MUST be merged to the main branch before they can be used
- After the initial merge, they should be tested from feature branches
**Debug Steps:**
Add debug steps that print non-secret parameters when:
- Creating a new action, OR
- Troubleshooting a particularly tricky issue
(Not required for every workflow - use when needed)
## Effectiveness Principles
Actions cost CI minutes. Be deliberate, not iterative:
1. **Monitor, don't poll** - use `gh run watch` / `gh pr checks --watch` to follow runs live
2. **Read logs, don't guess** - fetch the failed job's log before changing code
3. **Print actual values** - debug steps reveal the real `inputs`/`github` context, not your assumptions
4. **Test locally first** - `act` runs workflows on your machine and avoids burning CI minutes
5. **Plan the smallest reproduction** - one job, minimal matrix, narrow trigger before scaling up
See [README.md](README.md) for the full debugging workflow, `gh` commands, and YAML debug-step examples.
## Key Gotchas
…
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
