API Development Agent Skills

MCP Server Builder

Builds high-quality Model Context Protocol (MCP) servers in Python and TypeScript to integrate external APIs and services with LLMs.

Go Patterns & Best Practices (KR)

Implements idiomatic Go design patterns and best practices for building robust, high-performance applications.

Kotlin Ktor Backend Patterns

Implements production-ready Ktor server architectures using idiomatic Kotlin patterns, routing DSLs, and dependency injection.

Ai Agent Abort Condition Builder

Build and evaluate explicit stop, rollback, and escalation conditions for autonomous or batch workflows without executing runtime actions.

Claude API & SDK Reference

Streamlines the implementation of Anthropic Claude API features across Python and TypeScript development environments.

Kotlin Ktor Server Patterns

Implements production-ready Ktor server architectures with optimized patterns for routing, dependency injection, and security.

Claude API Integration Patterns

Provides production-ready code patterns and best practices for integrating Anthropic's Claude API into Python and TypeScript applications.

Claude API Integration

Provides standardized implementation patterns and best practices for building applications with Anthropic's Claude API using Python and TypeScript.

Backend Architecture Patterns

Implements scalable backend architectures, API design standards, and database optimizations for Node.js and Next.js applications.

REST API Design Patterns

Standardizes REST API architecture using consistent naming, semantic status codes, and scalable implementation patterns for production services.

Cost-Aware LLM Pipeline

Optimizes LLM API expenses by implementing intelligent model routing, budget tracking, and efficient caching strategies.

Realmint Rwa Intelligence

Query structured, machine-readable intelligence about tokenized real-world assets (RWAs) — ownership, control, transferability, redemption terms, legal backing, market data, and a six-dimension risk score. Use whenever an agent needs to evaluate, score, or vet an RWA before committing capital. Covers commodity-backed tokens (Tether Gold, PAX Gold, Kinesis), tokenized treasuries, tokenized equities (xStocks), and other indexed RWAs across multiple chains.

Developer Experience Plan Review

Audits and optimizes developer experience plans for APIs, SDKs, CLIs, and platforms to eliminate friction and elevate developer onboarding.

Spring Boot Production Patterns

Implements scalable, production-grade Spring Boot architectures using proven patterns for REST APIs, data access, and service orchestration.

Spring Boot Architecture Patterns

Implements production-grade Spring Boot architecture patterns for scalable Java backend services and RESTful APIs.

API Design Patterns

Implements industry-standard RESTful API conventions for resource naming, status codes, and scalable architecture.

Backend Architecture Patterns

Implements scalable server-side architectures, optimized API designs, and database best practices for Node.js and Next.js.

Java Coding Standards

Enforces modern Java 17+ and Spring Boot coding standards for clean, maintainable, and type-safe backend services.

Django Architecture Patterns

Provides production-grade Django architecture patterns, DRF API design, and ORM best practices for scalable web applications.

Realmint Agent Buy

Buy tokenized real-world assets (RWAs) as an autonomous agent — authenticate keyless with an EVM key, self-fund in USDC over the x402 payment protocol, and route a buy end-to-end. Use when an agent needs to actually acquire an RWA (not just evaluate it). Pairs with the read-only "Realmint — RWA Intelligence" skill for due diligence first.

Node.js Backend Architecture Patterns

Provides standardized backend architecture patterns, API design principles, and database optimization strategies for scalable Node.js and Next.js applications.

Backend Development Patterns

Implements scalable backend architectures, API designs, and database optimizations using industry-standard patterns for Node.js and Next.js.

Django Architecture Patterns

Implements scalable, production-grade Django architectures including DRF APIs, ORM optimization, and modular project structures.

Go Idiomatic Design Patterns

Implements idiomatic Go patterns, best practices, and robust implementation guidelines for building efficient and maintainable applications.

Java Spring Boot Coding Standards

Enforces production-grade Java 17+ coding standards and patterns for Spring Boot microservices.

REST API Design Patterns

Enforces industry-standard RESTful API conventions for resource naming, semantic status codes, and scalable backend architecture.

Claude API & SDK Integration

Integrates Anthropic's Claude API and SDKs into development workflows with best practices for models, adaptive thinking, and language-specific implementations.

Bun Zig-JS Class Generator

Generates high-performance JavaScriptCore class bindings from Zig implementations using Bun's codegen tools.

JSC C++ Class Implementation

Streamlines the creation of high-performance JavaScript classes in C++ using the JavaScriptCore engine.

DDD Bounded Context Scaffolder

Scaffolds and manages Domain-Driven Design bounded contexts with standard layered architecture, barrel exports, and memory graph integration.
