github-actions-workflow

github-actions-workflow is a skill for Claude Code, Codex from aj-geddes/useful-ai-prompts. It costs 33 tokens per session (559 once invoked), scanned A, original, MIT.

A guide to setting up GitHub Actions, GitHub's system for running automated jobs when code changes. It covers workflows made of jobs and steps for testing, building, security checks, and deployment.

In plain words
What is it for?
Use it to create GitHub Actions files for CI/CD, automated tests, security scanning, dependency updates, code-quality checks, deployments, and release tasks.
Why use it?
It helps replace repeated manual checks and releases with a defined process that runs from the repository. It also keeps testing and other checks consistent across changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

github-actions-workflow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-pipeline.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GitHub Actions Workflow

Table of Contents

Overview

Create powerful GitHub Actions workflows to automate testing, building, security scanning, and deployment processes directly from your GitHub repository.

When to Use

  • Continuous integration and testing
  • Build automation
  • Security scanning and analysis
  • Dependency updates
  • Automated deployments
  • Release management
  • Code quality checks

Quick Start

Minimal working example:

# .github/workflows/ci.yml
name: CI/CD Pipeline

on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main, develop]

env:
  REGISTRY: ghcr.io
  IMAGE_NAME: ${{ github.repository }}

jobs:
  test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [16.x, 18.x, 20.x]
    steps:
      - uses: actions/checkout@v3

      - name: Setup Node ${{ matrix.node-version }}
        uses: actions/setup-node@v3
        with:
// ... (see reference guides for full implementation)

Best Practices

✅ DO

  • Use caching for dependencies (npm, pip, Maven)
  • Run tests in parallel with matrix strategy
  • Require status checks on protected branches
  • Use environment secrets and variables
  • Implement conditional jobs with if:
  • Lint and format before testing
  • Set explicit permissions with permissions
  • Use runner labels for specific hardware
  • Cache Docker layers for faster builds

❌ DON'T

  • Store secrets in workflow files
  • Run untrusted code in workflows
  • Use secrets.* with pull requests from forks
  • Hardcode credentials or tokens
  • Miss error handling with continue-on-error
  • Create overly complex workflows
  • Skip testing on pull requests

Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
