What it does

This skill provides a comprehensive reference of implementation patterns that ensure an AI agent writes consistent, maintainable, and production-grade code. It focuses on matching existing codebase conventions rather than inventing new ones.

When to use it

Activate this skill when implementing common backend features such as:

Creating REST or GraphQL API endpoints
Implementing CRUD operations with proper error handling
Writing asynchronous event handlers with idempotency
Setting up environment configuration with schema validation
Implementing structured logging with context propagation

What's included

Instructions: Detailed patterns for CRUD (Validate -> Transform -> Persist -> Return), API flows (Parse -> Validate -> Execute -> Format), and Event handling.
References: Includes guides on violations and correct patterns in references/violations.md and references/patterns.md.
Checklists: A rigorous implementation checklist for verifying Result types, input validation, and idempotency.

Compatible agents

Designed for advanced agentic development toolkits like Claude Code, Codex, and other LLM-based CLI coding assistants that can read repository patterns.
