Generates GitHub Actions CI pipeline for automated testing and validation.

Purpose & Scope

Creates CI/CD workflow for GitHub:

• Does: Generate .github/workflows/ci.yml with lint, test, build, docker jobs
• Does NOT: Configure deployment, manage secrets, set up CD pipelines

Inputs

Outputs

Workflow

Phase 1: Stack Analysis

Determine which template to use:

Detect commands:

• Frontend: Read scripts from package.json (lint, build, test)
• .NET: Standard dotnet restore/build/test
• Python: pip install, ruff lint, pytest

Phase 2: Variable Substitution

Replace template variables:

Phase 3: Directory Creation

Create .github/workflows/ directory if not exists.

Phase 4: File Generation

Generate ci.yml from selected template:

1. Check if workflow already exists (warn before overwrite)
2. Apply variable substitution
3. Write to .github/workflows/ci.yml
4. Validate YAML syntax

Generated Pipeline Structure

Jobs Overview

Frontend Job Steps

1. Checkout code
2. Setup Node.js with caching
3. Install dependencies (npm ci)
4. Run linter (npm run lint)
5. Build application (npm run build)
6. Run tests (npm test)

Backend Job Steps (.NET)

1. Checkout code
2. Setup .NET SDK
3. Restore dependencies (dotnet restore)
4. Build (dotnet build)
5. Run tests (dotnet test)

Backend Job Steps (Python)

1. Checkout code
2. Setup Python with pip caching
3. Install dependencies (pip install -r requirements.txt)
4. Run linter (ruff check)
5. Run tests (pytest)

Docker Job Steps

1. Checkout code
2. Build images (docker compose build)
3. Start containers (docker compose up -d)
4. Wait for startup (30 seconds)
5. Health check frontend (port 3000)
6. Health check backend (port 5000/8000)
7. Show logs on failure
8. Stop containers (docker compose down)

Triggers

Best Practices Applied

Quality Criteria

Generated workflow must:

• Pass YAML syntax validation
• Use pinned action versions (not @latest)
• Include dependency caching
• Have health checks for docker job
• Clean up resources on completion

Critical Notes

1. GitHub Actions Only: This skill generates only GitHub Actions workflows. No Azure/GitLab support.
2. Template-based: Use templates from references/. Do NOT hardcode workflow contents.
3. Idempotent: Check if .github/workflows/ exists. Warn before overwriting ci.yml.
4. Version Detection: Use detected versions, not hardcoded defaults.
