I Built an AI Skill That Writes GitHub Actions Workflows — With Zero Config Errors A developer built an AI Skill that generates production-ready GitHub Actions workflows with zero configuration errors. The skill enforces 12 quality gates, 5 decision templates, and 3 mandatory security configs, ensuring least-privilege permissions, concurrency control, and SHA-1 pinned actions. It works with Claude Code, Cursor, GitHub Copilot, Windsurf, Aider, and Cline. Stop hand-crafting YAML. Let any AI agent generate production-ready workflows with 12 quality gates, 5 decision templates, and 3 mandatory security configs. Hand-writing GitHub Actions YAML is error-prone. Did you remember permissions ? Did you pin action versions? Did you configure caching? Is concurrency set? Every omitted config is either slower builds, security holes, or wasted billable minutes. I built an AI Skill — an executable instruction set, not a vague prompt. It forces any AI agent to follow a strict pipeline: Decision Tree → Mandatory Config Injection → Cache Matching → 12 Quality Gates → Production YAML "Add CI for my Node.js project — run eslint and jest on PRs" What the AI generates under the hood: package.json → Node.js permissions: contents: read injected concurrency with auto-cancel cache: 'npm' → ~70% faster installs @11bd71... not @v4 5 seconds. Zero omissions. | Approach | Universal | Security Check | Caching | Quality Gates | |---|---|---|---|---| | GitHub templates | ✅ | ❌ | ❌ | ❌ | | Manual YAML | ✅ | ❌ | ❌ | ❌ | | Raw ChatGPT prompt | ✅ | ❌ | ❌ | ❌ | This Skill | ✅ All agents | ✅ 5 red lines | ✅ 6 langs | ✅ 12 gates | Raw LLM chats miss configs every time. This Skill makes them mandatory , not optional. Every template enforces least-privilege permissions, concurrency control, and SHA-1 pinned actions — no exceptions. pull request target misuse → blocked @main / @master action refs → blocked permissions: write-all → blocked| Agent | How | |---|---| Claude Code | SKILL.md → .claude/skills/ | Cursor | PROMPT.md → .cursor/rules/ | GitHub Copilot | PROMPT.md → .github/copilot-instructions.md | Windsurf / Aider / Cline | Paste into System Prompt | International users | PROMPT.en.md English | ❌ Without Skill — typical raw LLM output name: CI on: push jobs: test: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 unpinned - run: npm install no cache - run: npm test no permissions, no concurrency ✅ With Skill — production-grade name: CI on: pull request: branches: main push: branches: main concurrency: group: ${{ github.workflow }}-${{ github.event.pull request.number || github.ref }} cancel-in-progress: true permissions: contents: read jobs: lint: runs-on: ubuntu-latest steps: - uses: actions/checkout@11bd71901bbe5b1630ceea73d27597364c9af683 v4.2.2 - uses: actions/setup-node@cd063736c72066a58f36dd95fb0460484b220fb7 v4.3.0 with: node-version: 20 cache: 'npm' - run: npm ci - run: npx eslint . test: needs: lint ... full pipeline git clone https://github.com/2B0748/github-actions-skill.git 👉 Star the repo if you find it useful.
