description	Starter file templates and boilerplate for scaffolding projects across frontend, backend, mobile, and AI agent frameworks. Sub-files: nextjs.md, react-vite.md, react-native.md, ios-swift.md, android-kotlin.md, frontend-config.md, nodejs.md, python.md, go.md, dotnet.md, nestjs.md, spring-boot.md

Project Templates

Starter templates for each supported framework. Used by the scaffolder agent to create real, working project scaffolds.

All framework templates are in dedicated sub-files — load the relevant sub-file for the target framework:

Sub-file	Covers
skills/project-templates/nextjs.md	Next.js (App Router)
skills/project-templates/react-vite.md	React (Vite), Vue/static builds
skills/project-templates/react-native.md	React Native (Expo Managed)
skills/project-templates/ios-swift.md	Swift / SwiftUI (native iOS)
skills/project-templates/android-kotlin.md	Kotlin / Jetpack Compose (native Android)
skills/project-templates/frontend-config.md	API client, auth, monitoring, realtime, state (all web frontends)
skills/project-templates/nodejs.md	Node.js / Express, BullMQ worker, Node.js agent
skills/project-templates/python.md	Python / FastAPI, Python agent
skills/project-templates/go.md	Go / Gin
skills/project-templates/dotnet.md	.NET / ASP.NET Core (Clean Architecture)
skills/project-templates/nestjs.md	NestJS
skills/project-templates/spring-boot.md	Java / Spring Boot (Maven)

For unlisted runtimes (Django, Rails, Laravel, Ionic, Angular, Hono, Remix, Astro, Flutter, Swift, Kotlin), the scaffolder generates starter files dynamically — the predefined templates serve as the quality benchmark.

DevOps Templates

GitHub Actions CI Workflow

Runtime-specific CI workflows are in the runtime sub-files (nodejs.md, python.md, go.md, dotnet.md).

docker-compose.yml — MANDATORY for all backend services

Every backend service MUST include a docker-compose.yml for local development. Web frontends SHOULD also include one if they have backend dependencies.

IMPORTANT — Port collision prevention: Each service in the architecture MUST use a unique host port. Assign ports sequentially starting from the manifest's dev_port for each component. Never use the same host port for two different services. Use the ${PORT:-{{dev-port}}} pattern so ports can be overridden via .env.

services:
  {{component-name}}:
    build: .
    ports:
      - "${PORT:-{{dev-port}}}:{{dev-port}}"
    env_file: .env
    depends_on:
      - db
      - redis

  # Add/remove services based on manifest databases.
  # Use unique host ports per component to avoid collisions across services.
  db:
    image: postgres:16-alpine
    environment:
      POSTGRES_DB: {{component-name}}
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
    ports:
      - "{{db-host-port}}:5432"
    volumes:
      - pgdata:/var/lib/postgresql/data

  redis:
    image: redis:7-alpine
    ports:
      - "{{redis-host-port}}:6379"

volumes:
  pgdata:

Port assignment strategy for multi-service architectures: When scaffolding multiple services, assign non-overlapping host ports for infrastructure containers:

• Service 1 DB: 5432, Redis: 6379
• Service 2 DB: 5433, Redis: 6380
• Service 3 DB: 5434, Redis: 6381
• And so on...

This prevents port collisions when running multiple services locally at the same time.

Shared Package Templates

Shared Types Package

Runtime-specific shared types packages are in the runtime sub-files:

• TypeScript (package.json, tsconfig, index.ts): skills/project-templates/nodejs.md
• Python (pyproject.toml, pydantic models): skills/project-templates/python.md

---

Common Files

These files are added to every project regardless of framework.

.editorconfig

Add to the repo root — enforces consistent formatting across editors and runtimes:

root = true

[*]
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

[*.{ts,tsx,js,jsx,json,yaml,yml,css,html}]
indent_style = space
indent_size = 2

[*.{py}]
indent_style = space
indent_size = 4

[*.{cs}]
indent_style = space
indent_size = 4

[*.go]
indent_style = tab
indent_size = 4

[Makefile]
indent_style = tab

dependabot.yml

Add to .github/dependabot.yml in the repo root:

version: 2
updates:
  # Node.js / npm
  - package-ecosystem: npm
    directory: "/"
    schedule:
      interval: weekly
    open-pull-requests-limit: 5
    groups:
      dev-dependencies:
        dependency-type: development

  # Python / pip
  - package-ecosystem: pip
    directory: "/"
    schedule:
      interval: weekly
    open-pull-requests-limit: 5

  # Go modules
  - package-ecosystem: gomod
    directory: "/"
    schedule:
      interval: weekly
    open-pull-requests-limit: 5

  # .NET / NuGet
  - package-ecosystem: nuget
    directory: "/"
    schedule:
      interval: weekly
    open-pull-requests-limit: 5

  # GitHub Actions
  - package-ecosystem: github-actions
    directory: "/"
    schedule:
      interval: weekly

Generate one block per package ecosystem present in the project. Always include the github-actions block.

Security Scanning Workflow

Add .github/workflows/security.yml — language-agnostic, works for all runtimes:

name: Security

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]
  schedule:
    - cron: "0 6 * * 1"   # weekly Monday 06:00 UTC

permissions:
  contents: read
  security-events: write   # required for CodeQL to upload SARIF results

jobs:
  secret-scan:
    name: Secret scanning (Gitleaks)
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0   # full history so Gitleaks can scan all commits

      - uses: gitleaks/gitleaks-action@v2
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

  codeql:
    name: SAST (CodeQL)
    runs-on: ubuntu-latest
    strategy:
      matrix:
        # Add only the languages present in this repo
        language: [javascript-typescript]
        # Other supported values: python, go, csharp, java, ruby, swift
    steps:
      - uses: actions/checkout@v4

      - uses: github/codeql-action/init@v3
        with:
          languages: ${{ matrix.language }}
          queries: security-and-quality

      - uses: github/codeql-action/autobuild@v3

      - uses: github/codeql-action/analyze@v3
        with:
          category: "/language:${{ matrix.language }}"

Language matrix values by runtime:

Runtime	language value
Node.js / TypeScript	javascript-typescript
Python	python
Go	go
.NET / C#	csharp
Multiple runtimes in monorepo	list all: [javascript-typescript, python]

CodeQL results appear in the GitHub Security tab → Code scanning alerts. No external accounts needed — it's built into GitHub.

.gitleaks.toml (optional — add to repo root to suppress false positives):

[allowlist]
description = "Global allowlist"
paths = [
  ".env.example",      # example files intentionally contain placeholder keys
]
regexes = [
  "EXAMPLE_",          # suppress vars named *_EXAMPLE_*
  "your-.*-here",      # suppress placeholder strings
]

.gitignore

Runtime-specific .gitignore files are in the runtime sub-files (nodejs.md, python.md, go.md, dotnet.md). Always add one per component.

.env.example

Generate from the manifest's integrations and environments. Format:

Backend service:

# Server
PORT={{dev-port}}
NODE_ENV=development

# {{service-name}} — {{category}}
# Get credentials at: {{signup-url}}
{{ENV_VAR_NAME}}=

Web frontend (Vite):

# API URLs — update per environment
# DEV:     http://localhost:{{backend-dev-port}}
# STAGING: {{staging-url}}
# PROD:    {{prod-url}}
VITE_API_URL=http://localhost:{{backend-dev-port}}

# WebSocket URL (if realtime is configured)
# VITE_WS_URL=ws://localhost:{{backend-dev-port}}

# Monitoring
# VITE_SENTRY_DSN=
# VITE_APP_INSIGHTS_KEY=

Mobile app (Expo):

# API URLs — update per environment
# DEV:     http://localhost:{{backend-dev-port}}
# STAGING: {{staging-url}}
# PROD:    {{prod-url}}
EXPO_PUBLIC_API_URL=http://localhost:{{backend-dev-port}}

# Push Notifications
# EXPO_PUBLIC_PUSH_PROJECT_ID=

# Monitoring
# EXPO_PUBLIC_SENTRY_DSN=

# OTA Updates
# EXPO_PUBLIC_UPDATE_URL=

Include a comment with the signup URL for each integration service so the user knows where to get credentials. Use environment URLs from the manifest's environments section.

Dockerfile — MANDATORY for all backends and agents

Every backend service, worker, and agent MUST include a Dockerfile. This is not optional.

Runtime-specific Dockerfiles are in the runtime sub-files:

• Node.js: skills/project-templates/nodejs.md
• Python: skills/project-templates/python.md
• Go: skills/project-templates/go.md (distroless static image)

Dockerfile — for web frontends (include where applicable)

Web frontends that produce a build artifact SHOULD include a Dockerfile. Skip only for mobile-only targets (Expo, Flutter).
