fastapi-vue

sdd-web-app

Claude Code plugin marketplace for AI-assisted web app development. Lighter and more batch-friendly than the original AIUP: no UML, no ceremony, generates monorepos.

Quick start

# 1. Install the marketplace
/plugin marketplace add ./sdd-web-app
/reload-plugins

# 2. In your project directory — start with the vision
/vision

# 3. Define requirements and architecture
/requirements
/architecture      # writes FastAPI+Vue3 default if docs/architecture.md is absent

# 4. Design the data model and feature specs
/data-model
/feature-spec      # generates all features from requirements at once

# 5. Implement + test everything in one go
/sprint

# 6. Ship
/ship
