Install Github Actions
Pick your agent. Every command is ready to paste.
npx skills add callstackincubator/agent-skills --skill github-actionsThe open skills CLI detects your agents (Claude Code, Cursor, Codex and 70+ more) and installs to the right folder. Add -g to install globally.
01
Install it
Run the command above, or upload the folder in Claude.
02
Ask naturally
Describe the task. Your agent loads github-actions when the request matches its description.
03
Name it if needed
If it does not trigger, say “use the github-actions skill”. In Codex, type $github-actions.

GitHub Actions Build Artifacts
Overview
Reusable GitHub Actions patterns to build React Native apps for iOS simulators and Android emulators in the cloud, then publish artifacts retrievable via gh CLI or GitHub API.
When to Apply
Use this skill when:
- Creating CI workflows that build React Native simulator/emulator artifacts.
- Uploading iOS simulator and Android emulator installables from PRs or manual dispatch runs.
- Replacing local-only mobile builds with downloadable CI artifacts.
- Needing stable artifact IDs/names for scripted retrieval with
ghor REST API.
Quick Reference
- Add composite actions from gha-ios-composite-action.md and gha-android-composite-action.md.
- Wire them into
.github/workflows/mobile-build.ymlfrom gha-workflow-and-downloads.md. - Upload with
actions/upload-artifact@v4and captureartifact-idoutput. - Download with
gh run downloadorGET /repos/{owner}/{repo}/actions/artifacts/{artifact_id}/{archive_format}.

Need CI iOS simulator .app.tar.gz artifact |
gha-ios-composite-action.md |
Need CI Android emulator .apk artifact |

| Need one workflow to trigger both platform jobs | gha-workflow-and-downloads.md |
| Need scripted artifact download | gha-workflow-and-downloads.md |

Tips for Github Actions
- • Start a fresh session after installing so your agent picks up the new skill.
- • It bundles reference files. The agent reads them only when needed, so they cost no context until then.
- • It is part of a pack with 13 skills. Install only the ones you need with --skill to keep triggers precise.
- • If two skills overlap, mention the one you want by name.
