# Using Web Backend Skills

## Overview

**This router directs you to specialized web backend skills. Each specialist provides deep expertise in their domain.**

**Core principle:** Different backend challenges require different specialist knowledge. Routing to the right skill gives better results than generic advice.

## When to Use

Use this router when encountering:

- **Framework-specific questions**: FastAPI, Django, Express implementation details
- **API design**: REST or GraphQL architecture, versioning, schema design
- **Architecture patterns**: Microservices, message queues, event-driven systems
- **Backend infrastructure**: Authentication, database integration, deployment
- **Testing & documentation**: API testing strategies, documentation approaches

## How to Access Reference Sheets

**IMPORTANT**: All reference sheets are located in the SAME DIRECTORY as this SKILL.md file.

When this skill is loaded from:
  `skills/using-web-backend/SKILL.md`

Reference sheets like `fastapi-development.md` are at:
  `skills/using-web-backend/fastapi-development.md`

NOT at:
  `skills/fastapi-development.md` ← WRONG PATH

When you see a link like `[fastapi-development.md](fastapi-development.md)`, read the file from the same directory as this SKILL.md.
