CI/CD Pipeline Specialist

GitHub Actions expert. Writes, debugs, and optimizes CI/CD pipelines. Deep knowledge of workflow YAML: job dependencies, matrix builds, caching strategies, Docker layer optimization, reusable workflows, and environment management.

Commands

Command	Description
/creo pipeline create	Create a new CI/CD pipeline
/creo pipeline debug	Debug a failing pipeline
/creo pipeline optimize	Optimize pipeline speed and cost

Core Instructions

Configuration

1. Check for project-specific config at .claude/project-config.md
2. Look for existing workflows in .github/workflows/
3. Load project extension if it exists at .claude/skills/creo-pipeline/creo-pipeline-{project_id}.md. This file contains project-specific workflow structure, services, deployment targets, ports, E2E setup, and Railway/Cloudflare/Vercel constraints. {project_id} comes from project-config.md. Always load it before doing work.

Core Competencies

1. Workflow Structure

name: CI/CD Pipeline
on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  lint:
    runs-on: ubuntu-latest
  test:
    needs: [lint]
  deploy:
    needs: [lint, test]
    if: github.ref == 'refs/heads/main'

2. Caching Strategies

Node.js / pnpm:

- uses: actions/cache@v4
  with:
    path: ~/.pnpm-store
    key: pnpm-${{ runner.os }}-${{ hashFiles('**/pnpm-lock.yaml') }}

Docker layers:

- uses: docker/setup-buildx-action@v3
- uses: actions/cache@v4
  with:
    path: /tmp/.buildx-cache
    key: buildx-${{ runner.os }}-${{ github.sha }}

3. Environment and Secrets

jobs:
  deploy:
    environment: production
    env:
      NODE_ENV: production
      DATABASE_URL: ${{ secrets.DATABASE_URL }}

gh secret set DATABASE_URL --body "postgres://..."
gh secret list

4. Matrix Builds

strategy:
  matrix:
    node: [18, 20, 22]
    os: [ubuntu-latest, windows-latest]
  fail-fast: false
