# Conditional Request Helper

## Overview

This skill provides automated assistance for conditional request helper tasks within the API Development domain.

## When to Use

This skill activates automatically when you:
- Mention "conditional request helper" in your request
- Ask about conditional request helper patterns or best practices
- Need help with api development skills covering rest, graphql, openapi, authentication, and api design patterns.

## Instructions

1. Provides step-by-step guidance for conditional request helper
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 conditional request helper"
Result: Provides step-by-step guidance and generates appropriate configurations


## Prerequisites

- Relevant development environment configured
- Access to necessary tools and services
- Basic understanding of api 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 provides automated assistance for configuring and using conditional request helper operations in API development. It auto-activates when conditional request helper phrases are detected and delivers step-by-step guidance, production-ready snippets, and validation advice. Use it to implement conditional requests, optimize caching, and enforce request preconditions across REST, GraphQL, and OpenAPI surfaces.

How this skill works

The skill inspects your prompt for trigger phrases like "conditional request helper" or "conditional helper" and responds with targeted guidance. It generates configuration snippets, sample code, and validation checks for common conditional patterns (ETag, If-Modified-Since, If-Match, conditional headers). It also highlights potential errors, suggests remediation, and aligns outputs with API design best practices.

When to use it

When implementing conditional GET/PUT semantics using ETag or Last-Modified.
When designing cache-friendly endpoints or reducing payloads with 304 Not Modified responses.
When validating preconditions for safe updates (If-Match/If-Unmodified-Since).
When mapping conditional behavior in OpenAPI or Swagger specs.
When you need production-ready code examples for REST or GraphQL conditional flows.

Best practices

Prefer ETag for precise resource versioning and If-None-Match for efficient cache validation.
Document conditional behavior clearly in OpenAPI/Swagger with examples and response codes.
Fail fast with clear 412/428 responses for unmet preconditions and include guidance for clients to recover.
Test conditional flows using automated integration tests that simulate concurrent updates and stale clients.
Log conditional header evaluations for debugging and metrics, including hits, misses, and precondition failures.

Example use cases

Add ETag generation and If-None-Match handling to an existing REST endpoint to enable 304 responses.
Define conditional update semantics in OpenAPI and generate server stubs that enforce If-Match checks.
Create a GraphQL resolver pattern that uses a version field plus conditional headers to prevent lost updates.
Generate sample client code showing how to send If-Modified-Since or If-None-Match to minimize bandwidth.
Validate and lint API specs to ensure conditional headers and response codes are declared and documented.

FAQ

What conditional headers should I use for caching?

Use ETag with If-None-Match for precise cache validation; Last-Modified with If-Modified-Since is a lighter alternative when exact versioning is not required.

How do I handle concurrent updates safely?

Require a version token (ETag) from clients and enforce If-Match on update operations. Return 412 Precondition Failed if the token does not match and provide the current resource representation or new ETag.
