CI/CD Pipeline Builder
Tier: POWERFUL
Category: Engineering
Domain: DevOps / Automation
Overview
Use this skill to generate pragmatic CI/CD pipelines from detected project stack signals, not guesswork. It focuses on fast baseline generation, repeatable checks, and environment-aware deployment stages.
Core Capabilities
- Detect language/runtime/tooling from repository files
- Recommend CI stages (
lint,test,build,deploy) - Generate GitHub Actions or GitLab CI starter pipelines
- Include caching and matrix strategy based on detected stack
- Emit machine-readable detection output for automation
- Keep pipeline logic aligned with project lockfiles and build commands
When to Use
- Bootstrapping CI for a new repository
- Replacing brittle copied pipeline files
- Migrating between GitHub Actions and GitLab CI
- Auditing whether pipeline steps match actual stack
- Creating a reproducible baseline before custom hardening
Key Workflows
1. Detect Stack
Supports input via stdin or --input file for offline analysis payloads.
2. Generate Pipeline From Detection
Or end-to-end from repo directly:
3. Validate Before Merge
- Confirm commands exist in project (
test,lint,build). - Run generated pipeline locally where possible.
- Ensure required secrets/env vars are documented.
- Keep deploy jobs gated by protected branches/environments.
4. Add Deployment Stages Safely
- Start with CI-only (
lint/test/build). - Add staging deploy with explicit environment context.
- Add production deploy with manual gate/approval.
- Keep rollout/rollback commands explicit and auditable.
Script Interfaces
