github-actions

github-actions is a skill for Claude Code, Codex from G1Joshi/Agent-Skills. It costs 19 tokens per session (489 once invoked), scanned A, original, MIT.

GitHub's built-in automation system for running tasks when code changes or other repository events occur. Workflows use reusable steps called actions and run on hosted or self-managed machines.

In plain words
What is it for?
Use it to run tests on pushes and pull requests, build software, deploy releases, schedule jobs, and create reusable automation workflows.
Why use it?
It automates checks and delivery directly alongside the code, reducing manual build, test, and deployment work.

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 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 4d ago.

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.

What it actually says

GitHub Actions

GitHub Actions is the CI/CD platform native to GitHub. In 2025, it is the dominant CI/CD tool, characterized by Reusable Workflows and OIDC integration for passwordless deployments.

When to Use

  • GitHub-Hosted: Your code is already on GitHub. Deep integration with Issues/PRs.
  • Simplicity: No servers to manage (unlike Jenkins).
  • Marketplace: Thousands of pre-built actions (setup-node, docker-build-push).

Quick Start

# .github/workflows/ci.yml
name: CI
on: [push, pull_request]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: "20"
      - run: npm ci
      - run: npm test

Core Concepts

Workflows

Defined in .github/workflows/*.yml. Triggered by events (push, release, schedule).

Runners

Virtual machines (Ubuntu/Windows/MacOS) that run your jobs. You can also host Self-Hosted Runners for cheaper/faster builds in your VPC.

Actions

Reusable steps. actions/checkout is an action. You can write your own in JS or Docker.

Best Practices (2025)

Do:

  • Use Reusable Workflows: Define a standard "Deploy to Prod" workflow in one repo, and call it from 50 microservices.
  • Use OIDC: Authenticate to AWS/Azure/GCP using permissions: id-token: write instead of long-lived secrets.
  • Pin Actions: Use actions/checkout@v4 or a specific SHA for immutability.

Don't:

  • Don't hardcode secrets: Use Repository Secrets or Environment Secrets.
  • Don't write huge shell scripts: If a step is >10 lines of bash, move it to a script file or a custom Action.

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.
