github-actions

A tool for creating or improving GitHub Actions workflows, which are automated jobs that run checks or deployments when code changes.

In plain words
What is it for?
It helps run tests, linting, and type checks on pull requests; build or deploy applications; cache dependencies; test multiple runtime versions; and cancel outdated runs.
Why use it?
It removes the need to assemble continuous integration, deployment, release, or linting workflows by hand and helps check the project's existing setup first.

Made for: Claude Code, Codex.

Per session 12 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.
When invoked 320 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 3d 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 Workflow

Type: $1 (ci | deploy | release | lint - or auto-detect)

  1. Check existing workflows:
ls .github/workflows/ 2>/dev/null
cat package.json | grep '"scripts"' -A 20
  1. Generate the appropriate workflow:

CI (test + lint on PR):

name: CI
on: [pull_request]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with: { node-version: '20', cache: 'npm' }
      - run: npm ci
      - run: npm run lint
      - run: npm test
      - run: npm run typecheck
  1. Add optimizations:

    • Dependency caching (actions/cache)
    • Matrix testing for multiple Node/Python versions if needed
    • Fail-fast vs complete runs
    • Concurrency groups (cancel in-progress on new push)
  2. For deploy workflows: ask for target platform (Vercel, Railway, AWS, Fly.io, etc.)

  3. Save to .github/workflows/<type>.yml

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.

github-actions is a skill published in the GitHub repository berkcangumusisik/claude-code-practices (10 stars, last pushed 4mo ago), licensed MIT. It adds 12 tokens to every session and 320 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
