# Request Validator Generator

## Overview

This skill provides automated assistance for request validator generator tasks within the Backend Development domain.

## When to Use

This skill activates automatically when you:
- Mention "request validator generator" in your request
- Ask about request validator generator patterns or best practices
- Need help with backend skills covering node.js, python, go, database design, caching, messaging, and microservices architecture.

## Instructions

1. Provides step-by-step guidance for request validator generator
2. Follows industry best practices and patterns
3. Generates production-ready code and configurations
4. Validates outputs against common standards

## Examples

**Example: Basic Usage**
Request: "Help me with request validator generator"
Result: Provides step-by-step guidance and generates appropriate configurations


## Prerequisites

- Relevant development environment configured
- Access to necessary tools and services
- Basic understanding of backend development concepts


## Output

- Generated configurations and code
- Best practice recommendations
- Validation results


## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| Configuration invalid | Missing required fields | Check documentation for required parameters |
| Tool not found | Dependency not installed | Install required tools per prerequisites |
| Permission denied | Insufficient access | Verify credentials and permissions |


## Resources

- Official documentation for related tools
- Best practices guides
- Community examples and tutorials

Overview

This skill automates creation of request validator generator operations for backend projects. It produces step-by-step guidance, production-ready validation code, and configuration snippets compatible with Node.js, Python, and Go. The output focuses on secure, maintainable validators that integrate with common frameworks and CI pipelines.

How this skill works

The skill inspects request shapes, schemas, and endpoint contracts you provide and generates validation logic, schema definitions (JSON Schema, Joi, Pydantic, or Go structs), and example middleware. It validates generated artifacts against common standards, suggests fixes for missing fields, and produces test cases and CI snippets to run validation checks. It can also recommend error-handling and logging patterns to ensure predictable API behavior.

When to use it

  • When you need consistent request validation across multiple services or languages
  • When defining API contracts or converting OpenAPI/JSON Schema into runtime validators
  • When hardening inputs to prevent injection, type errors, or malformed payloads
  • When automating validator generation for microservices or API gateways
  • When creating test cases and CI checks for request validation

Best practices

  • Start from canonical schemas (OpenAPI/JSON Schema) and generate code from source of truth
  • Validate both structure and semantic constraints (types, formats, enums, business rules)
  • Keep validators deterministic and side-effect free; handle errors at a single middleware layer
  • Include clear error payloads and status codes for client feedback
  • Add unit tests and CI checks to prevent regressions when schemas change

Example use cases

  • Generate Joi middleware for a Node.js POST /users endpoint from an OpenAPI request schema
  • Create Pydantic models and FastAPI request validators for a Python microservice
  • Produce Go struct tags and validation functions for an HTTP service with strict typing
  • Auto-generate test payloads and negative test cases to verify validation behavior
  • Integrate schema validation into CI to fail builds on incompatible contract changes

FAQ

Which schema formats does this skill support?

It supports JSON Schema and OpenAPI specs and can map them to Joi, Pydantic, and Go structs.

Can it generate validators that run in middleware?

Yes — it produces example middleware for frameworks like Express, FastAPI, and net/http with clear instructions for integration.
