github-actions-ci

github-actions-ci is a skill for Claude Code, Codex from vikasudasi/skill-vault. It costs 29 tokens per session (1,012 once invoked), scanned A, original, Apache-2.0.

A guide to setting up GitHub Actions continuous integration. GitHub Actions runs automated jobs when code is pushed or a pull request is opened; these jobs can check formatting, types, and tests.

In plain words
What is it for?
Use it to create workflow files, install dependencies with caching, run tests and code checks, use matrix builds, handle secrets, and enforce merge gates.
Why use it?
It catches problems before code is merged and can prevent a pull request from being accepted when required checks fail.

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-ci 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.

GitHub Actions Continuous Integration

Use when wiring a repo so every push/PR runs lint, type-check, format-check, and tests — and blocks merge when they fail. This is exactly what Skill Vault's own CI does: test, ruff check, mypy, and ruff format --check running as a pre-merge gate.

Anatomy

name: CI
on:
  push:
    branches: [main]
  pull_request:
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: "3.11"
          cache: "pip"
      - run: pip install -e ".[dev]"
      - run: pytest
  • on defines triggers: push to main, every PR, schedule for cron.
  • Each job runs on its own fresh runner — share nothing between jobs; combine steps that need the same environment.

Checkout + setup-python caching

actions/checkout@v4 fetches the repo. setup-python with cache: "pip" caches the pip download cache/Ci keyed to your lockfile, cutting install time. Pin action versions by tag (@v4) or, for supply-chain rigor, by SHA.

The quality gate

Structure the gate so a single failed check blocks merge (protect the branch with "Require status checks to pass before merging"):

step command failure meaning
lint ruff check . style/import errors
typecheck mypy skill_vault type errors
format-check ruff format --check . not formatted
test pytest behaviour broken

Keep the gate fast — it runs on every commit. Run test as its own job so it can cache longer and fail independently. Add a coverage threshold (pytest-cov --cov-fail-under=85) so regressions also block.

Caching dependencies

- uses: actions/cache@v4
  with:
    path: ~/.cache/pip
    key: ${{ runner.os }}-pip-${{ hashFiles('pyproject.toml') }}

What ships with it

2 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.
