github-actions

A guide and generator for GitHub Actions, the automation system built into GitHub repositories. It creates workflow files for testing, deployment, releases, Docker builds, reusable workflows, custom actions, and dependency updates.

In plain words
What is it for?
Use it to generate, debug, and harden files in .github/workflows, including pipelines, releases, Docker jobs, reusable workflows, composite actions, and Dependabot configuration.
Why use it?
It removes the need to design CI/CD automation and its security settings from scratch. CI/CD means automatically checking, building, and releasing code.

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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 400 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub Actions Workflow Generator

Generate production-ready GitHub Actions workflow YAML files. Supports CI, CD, releases, Docker, reusable workflows, composite actions, and dependabot configs across multiple languages and frameworks.

Principles

  • Secure by default: Pin actions to SHA, minimal permissions, no hardcoded secrets
  • Cache everything: Dependencies, build artifacts, Docker layers — always cache
  • Fail fast, fail clear: Matrix fail-fast: true for CI, false for releases
  • Concurrency control: Always add concurrency groups for push/PR workflows
  • DRY workflows: Extract shared logic into reusable workflows or composite actions

MODE DETECTION (FIRST STEP)

Analyze the user's request to determine workflow type:

Request Pattern Mode Jump To
"CI", "test", "lint", "check" CI Phase 1–5
"deploy", "CD", "release to" DEPLOY Phase 1–5
"release", "publish", "tag" RELEASE Phase 1–5
"Docker", "container", "image" DOCKER Phase 1–5
"reusable workflow", "shared workflow" REUSABLE Phase 1–5
"composite action", "custom action" COMPOSITE Phase 1–5
"dependabot", "renovate", "dependency updates" DEPENDENCY Phase 1–5
"fix workflow", "workflow failing" DEBUG Debug Flow

Phase 1: Project Detection (PARALLEL)

Execute ALL in parallel:

# Group 1: Language detection
ls composer.json package.json pubspec.yaml go.mod Cargo.toml pyproject.toml setup.py requirements.txt Gemfile pom.xml build.gradle 2>/dev/null

# Group 2: Framework detection
ls artisan next.config.* nuxt.config.* angular.json vite.config.* 2>/dev/null
cat composer.json 2>/dev/null | head -20
cat package.json 2>/dev/null | head -20

# Group 3: Existing workflows
ls .github/workflows/*.yml .github/workflows/*.yaml 2>/dev/null
ls .github/actions/*/action.yml 2>/dev/null
cat .github/dependabot.yml 2>/dev/null

# Group 4: CI tooling
ls .php-cs-fixer.dist.php phpstan.neon pint.json eslint.config.* .eslintrc* biome.json analysis_options.yaml .golangci.yml .flake8 pyproject.toml 2>/dev/null

# Group 5: Docker context
ls Dockerfile docker-compose.yml docker-compose.yaml 2>/dev/null

Files

What ships with it

3 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.

github-actions is a skill published in the GitHub repository anilcancakir/claude-code-plugin (2 stars, last pushed 4mo ago), licensed MIT. It adds 43 tokens to every session and 2,976 once invoked, about $0.0002 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.
