ln-732-cicd-generator

Type: L3 Worker Category: 7XX Project Bootstrap

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

Input Source Description

Stack Type ln-730 coordinator backend-dotnet, backend-python

Versions Auto-detected Node.js, .NET or Python versions

Frontend Path Auto-detected Path to frontend directory

Build Commands Auto-detected npm scripts, dotnet/pytest commands

Outputs

File Purpose Template

.github/workflows/ci.yml

Main CI pipeline github_ci_dotnet.template.yml or github_ci_python.template.yml

Workflow

Phase 1: Stack Analysis

Determine which template to use:

Detection Backend Template

.sln or .csproj present github_ci_dotnet.template.yml

requirements.txt or pyproject.toml present github_ci_python.template.yml

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:

Variable Source Default

{{NODE_VERSION}}

package.json engines 22

{{DOTNET_VERSION}}

*.csproj TargetFramework 9.0.x

{{PYTHON_VERSION}}

pyproject.toml 3.12

{{FRONTEND_PATH}}

Directory detection src/frontend

Phase 3: Directory Creation

Create .github/workflows/ directory if not exists.

Phase 4: File Generation

Generate ci.yml from selected template:

• Check if workflow already exists (warn before overwrite)

• Apply variable substitution

• Write to .github/workflows/ci.yml

• Validate YAML syntax

Generated Pipeline Structure

Jobs Overview

Job Purpose Dependencies

frontend Lint, build, test React/Vite None

backend Build, test .NET or Python None

docker Build images, health checks frontend, backend

Frontend Job Steps

• Checkout code

• Setup Node.js with caching

• Install dependencies (npm ci )

• Run linter (npm run lint )

• Build application (npm run build )

• Run tests (npm test )

Backend Job Steps (.NET)

• Checkout code

• Setup .NET SDK

• Restore dependencies (dotnet restore )

• Build (dotnet build )

• Run tests (dotnet test )

Backend Job Steps (Python)

• Checkout code

• Setup Python with pip caching

• Install dependencies (pip install -r requirements.txt )

• Run linter (ruff check )

• Run tests (pytest )

Docker Job Steps

• Checkout code

• Build images (docker compose build )

• Start containers (docker compose up -d )

• Wait for startup (30 seconds)

• Health check frontend (port 3000)

• Health check backend (port 5000/8000)

• Show logs on failure

• Stop containers (docker compose down )

Triggers

Event Branches

Push main, develop

Pull Request main

Best Practices Applied

Practice Implementation

Dependency caching npm cache, pip cache

Pinned versions actions/checkout@v4, setup-node@v4

Parallel jobs frontend and backend run in parallel

Fail fast docker job waits for both to succeed

Clean up docker compose down runs always

Debug support logs shown on failure

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

• GitHub Actions Only: This skill generates only GitHub Actions workflows. No Azure/GitLab support.

• Template-based: Use templates from references/. Do NOT hardcode workflow contents.

• Idempotent: Check if .github/workflows/ exists. Warn before overwriting ci.yml.

• Version Detection: Use detected versions, not hardcoded defaults.

Reference Files

File Purpose

github_ci.template.yml Full template with comments

github_ci_dotnet.template.yml Compact .NET stack template

github_ci_python.template.yml Compact Python stack template

Definition of Done

• .github/workflows/ci.yml generated and passes YAML validation

• Pipeline includes lint, build, test, and docker jobs

• All action versions pinned (not @latest )
