Backend Development Patterns

Backend architecture patterns and best practices for scalable server-side applications.

When to Use

  • This skill is applicable to execute the workflow or actions described in the overview.

Core Workflow

  1. Confirm the request matches this skill's trigger, scope, and risk profile.
  2. Use the topic map to identify the relevant pattern, checklist, or example before writing detailed guidance or code.
  3. Load references/full-guidance.md when implementation details, examples, anti-patterns, validation checks, or edge cases are needed.
  4. Apply only the relevant guidance instead of loading or repeating the entire reference by default.
  5. Verify the result against any validation checks, limitations, security notes, or platform constraints in the reference.

Topic Map

  • API Design Patterns
  • RESTful API Structure
  • Repository Pattern
  • Service Layer Pattern
  • Middleware Pattern
  • Database Patterns
  • Query Optimization
  • N+1 Query Prevention
  • Transaction Pattern
  • Caching Strategies
  • Redis Caching Layer
  • Cache-Aside Pattern
  • Error Handling Patterns
  • Centralized Error Handler
  • Retry with Exponential Backoff
  • Authentication & Authorization
  • JWT Token Validation
  • Role-Based Access Control

Reference Map

  • references/full-guidance.md preserves the complete original guidance, including examples and detailed edge cases.

Limitations

  • Use this skill only when the task clearly matches the scope described above.
  • Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
  • Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

Progressive Loading

Keep this SKILL.md as the compact routing and workflow entrypoint. Load the reference file only when the user task requires the deeper implementation material.

Said here and by no other author read

  • Confirm the request matches the skill scope
  • Identify the relevant pattern before writing code
  • Load detailed guidance only when implementation details are needed
  • Apply only the relevant guidance from references
  • Verify results against validation checks and constraints
  • Stop and ask for clarification if inputs are missing

Grouped from the skills themselves: near-identical wordings counted once, and counted by distinct author, so one author publishing three of these counts once. Length counted with cl100k_base; the agent that loads this file may tokenize it differently.
