Middleware Chain Designer Skill

Overview

This skill designs middleware and interceptor chain architectures that enable SDK extensibility through pluggable request/response processing.

Capabilities

• •Design middleware interfaces and contracts
• •Implement interceptor chains with ordering
• •Support before/after hooks for requests
• •Enable custom transport implementations
• •Implement retry and circuit breaker middleware
• •Design logging and tracing interceptors
• •Support middleware composition
• •Configure middleware priority ordering

Target Processes

• •Plugin and Extension Architecture
• •Custom Transport and Middleware
• •SDK Architecture Design

Integration Points

• •SDK core HTTP clients
• •Authentication handlers
• •Logging frameworks
• •Retry libraries
• •Custom transports

Input Requirements

• •Extensibility requirements
• •Middleware ordering needs
• •Hook types required
• •Composition patterns
• •Transport abstraction needs

Output Artifacts

• •Middleware interface definitions
• •Interceptor chain implementation
• •Built-in middleware (logging, retry)
• •Transport abstraction layer
• •Middleware composition utilities
• •Documentation and examples

Usage Example

skill:
  name: middleware-chain-designer
  context:
    middlewareTypes:
      - request
      - response
      - error
    hooks:
      beforeRequest: true
      afterResponse: true
      onError: true
    builtInMiddleware:
      - logging
      - retry
      - timeout
      - compression
    ordering:
      priority: true
      named: true
    transports:
      - http
      - websocket
      - custom

Best Practices

1. •Define clear middleware interfaces
2. •Support ordered execution
3. •Enable middleware composition
4. •Provide built-in common middleware
5. •Allow transport customization
6. •Document middleware authoring
