CI/CD Pipeline Builder Skill
Designs and writes CI/CD pipelines for GitHub Actions, GitLab CI, or any other platform — test, lint, build, and deploy stages with caching, matrix builds, and environment-specific deployment logic.
Writing a CI/CD pipeline from scratch means reading documentation for an afternoon, iterating through YAML syntax errors, and eventually getting something that mostly works. This skill produces a working pipeline on the first pass — with caching, proper job dependencies, and the environment-specific logic that always gets left out of tutorials.
What the skill does
- Full pipeline generation. Test, lint, build, and deploy stages wired together with correct dependencies and failure handling.
- Dependency caching. Proper cache configuration for npm, pip, Maven, Gradle, or Go modules — the single biggest impact on pipeline speed.
- Matrix builds. Multi-version and multi-platform testing configurations.
- Environment-specific deployments. Staging deploys on push to
main, production deploys on tags, with manual approval gates where needed. - Secrets handling. Correct patterns for passing secrets to jobs without exposing them in logs.
- Optimisation. Parallel jobs, conditional steps, and cache strategies that cut pipeline time without cutting corners.
- Debugging. Diagnoses existing pipeline failures from error output and config.
How it works
- Describe the project. Language, framework, how tests are run, how the app is deployed (Docker, serverless, static hosting, etc.), and any specific requirements.
- Specify the platform. GitHub Actions, GitLab CI, CircleCI, Bitbucket Pipelines — the skill adapts the syntax.
- Pipeline draft. A complete YAML file for the platform, ready to commit.
- Iteration. Ask to add a stage, adjust the deployment logic, or optimise for speed.

.claude/commands/. Full walkthrough in the import tutorial. - Invoke the skill:
Or specify the setup:/cicd-builder/cicd-builder GitHub Actions. Node.js 20, tests with Jest, Docker build, deploy to Fly.io on main. Deploy to production only on version tags.
Quick-start prompt (no download)
Write a complete CI/CD pipeline configuration for [platform: GitHub Actions / GitLab CI / etc.].
The pipeline should:
- Run on every push and pull request
- Install dependencies with caching (so repeated runs skip the download)
- Run linting and tests in parallel where possible
- Build a production artifact (Docker image / compiled binary / static files)
- Deploy to staging on merge to main
- Deploy to production on version tags (vX.Y.Z), with a manual approval step
Include:
- Correct job dependency declarations (needs:)
- Proper secrets handling — never echo secrets to logs
- Failure notifications or status checks
- Comments explaining non-obvious configuration choices
Project: [language, framework, how tests are run] Deployment target: [where the app runs — Fly.io, AWS, GCP, VPS, etc.] Special requirements: [anything specific — monorepo, multiple services, specific Node/Python version matrix, etc.]
Tips:
- Ask for a minimal pipeline first if you are starting from scratch — get it green, then add complexity.
- Caching is the highest-leverage optimisation; ask the skill to double-check your cache key strategy if builds feel slow.
- If jobs are failing intermittently, paste the error output — flaky tests, race conditions, and network timeouts have distinct signatures in CI logs.
- For monorepos, ask for path-filtered triggers so each service's pipeline only runs when its own files change.
