Backend Skill

This skill contains routes to references that should be read before dealing with backend-related problems.

Standards

• Testable code patterns
• SOLID principle
• Race condition prevention code

Tree of Thought

Determine which condition applies before reading references.

Condition 1 — Empty Project

Triggered when starting a new backend project from scratch.

1. Read project-structure reference
2. Read ddd-vs-simple-model reference
3. Read coding-patterns reference
4. Read bootstrap reference
5. Determine what system design pattern could be useful → read relevant system design references below

Condition 2 — Existing Project

Triggered when working with an existing backend codebase.

1. Read project-pattern-recognition reference
2. Read code-pattern-recognition reference
3. Read pattern-refactoring-recognition reference
4. Read existing-documentation-context reference
5. Determine what system design pattern might be needed or not needed → read relevant system design references below

Routes

Templates

Template	Description
markdown	Template for writing markdown documentation

Fundamental

Reference	Description
project-structure	read this reference when deciding project architecture (CSR, CQRS, Clean Architecture, Hexagonal Pattern)
ddd-vs-simple-model	read this reference when deciding between DDD or a simple model approach
coding-patterns	read this reference when defining coding conventions (one file one function vs one file multiple functions)
bootstrap	read this reference when bootstrapping files and folders (logging, routing, controllers, configs, env loader, middlewares)
project-pattern-recognition	read this reference when recognizing patterns in an existing project structure
code-pattern-recognition	read this reference when recognizing code-level patterns in an existing codebase
pattern-refactoring-recognition	read this reference when identifying refactoring opportunities in project and code patterns
existing-documentation-context	read this reference when gathering context from existing documentation
