What it does

GitHub Actions is an agent skill from callstackincubator/agent-skills, published by the product's own GitHub organization. GitHub Actions workflow patterns for React Native iOS simulator and Android emulator cloud builds with downloadable artifacts. Use when setting up CI build pipelines or downloading GitHub Actions artifacts via gh CLI and GitHub API.

Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `agents/openai.yaml`, `references/gha-android-composite-action.md` and `references/gha-ios-composite-action.md`).

It sits in DevOps & Cloud, covering CI/CD and Cross-platform mobile apps. It works with GitHub Actions, Android, iOS and React Native. The repository describes itself as: A collection of agent-optimized React Native skills for AI coding assistants. The licence is MIT.

When your agent uses it

  • Setting up CI build pipelines
  • Downloading GitHub Actions artifacts via gh CLI and GitHub API

Example prompts

  • “/github-actions”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Add composite actions from gha-ios-composite-action.md and gha-android-composite-action.md.
  2. Wire them into .github/workflows/mobile-build.yml from gha-workflow-and-downloads.md.
  3. Upload with actions/upload-artifact@v4 and capture artifact-id output.
  4. Download with gh run download or GET /repos/{owner}/{repo}/actions/artifacts/{artifact_id}/{archive_format}.

What it can do on your machine

Read from SKILL.md and the folder at commit 61e6e7d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

GitHub Actions loads about 703 tokens when it runs, and up to ~6.4k if it reads all its reference files. Until then it costs about 62 tokens; SKILL.md has 195 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~703
With references · SKILL.md plus every file in references/, read only if the agent opens them
~6.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 gh or REST API.

Quick Reference

  1. Add composite actions from gha-ios-composite-action.md and gha-android-composite-action.md.
  2. Wire them into .github/workflows/mobile-build.yml from gha-workflow-and-downloads.md.
  3. Upload with actions/upload-artifact@v4 and capture artifact-id output.
  4. Download with gh run download or GET /repos/{owner}/{repo}/actions/artifacts/{artifact_id}/{archive_format}.
