What ci-cd-pipeline-builder does

The skill inspects project files and lockfiles using scripts/stack_detector.py. It identifies tooling and build commands, returning plain text or JSON output. The scripts/pipeline_generator.py script then takes this payload to create starter workflows for GitHub Actions or GitLab CI.

Generated configurations cover standard CI stages including lint, test, and build. Caching rules and build matrix strategies are added automatically to match the detected runtime. Deployment stages handle staging environments and manual approval gates for production rollouts.

Running the scripts requires python3. Use this skill when bootstrapping new repositories without manually copying stale YAML templates. Teams with heavily customized release infrastructure will still need to adapt the output.

What it helps with

  • generate baseline workflows for GitHub Actions or GitLab CI
  • detect runtimes and build commands from project lockfiles
  • configure dependency caching and matrix build strategies
  • set up staging and production deploy stages with approval gates

Example prompts for the agent

  • Inspect repository stack and generate a GitHub Actions workflow for lint, test, and build
  • Create a .gitlab-ci.yml pipeline with caching enabled for this repository
  • Run scripts/stack_detector.py and output the detected stack as JSON

# 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

```bash
python3 scripts/stack_detector.py --repo . --format text
python3 scripts/stack_detector.py --repo . --format json > detected-stack.json
```

Supports input via stdin or `--input` file for offline analysis payloads.

### 2. Generate Pipeline From Detection

```bash
python3 scripts/pipeline_generator.py \
  --input detected-stack.json \
  --platform github \
  --output .github/workflows/ci.yml \
  --format text
```

Or end-to-end from repo directly:

```bash
python3 scripts/pipeline_generator.py --repo . --platform gitlab --output .gitlab-ci.yml
```

### 3. Validate Before Merge

1. Confirm commands exist in project (`test`, `lint`, `build`).
2. Run generated pipeline locally where possible.
3. Ensure required secrets/env vars are documented.
4. 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

- `python3 scripts/stack_detector.py --help`
  - Detects stack signals from repository files
  - Reads optional JSON input from stdin/`--input`
- `python3 scripts/pipeline_generator.py --help`
  - Generates GitHub/GitLab YAML from detection payload
  - Writes to stdout or `--output`
