Build, debug, and extend integrations with the EasyPost shipping API. Use this skill whenever the user mentions EasyPost, shipping labels, postage, rate shopping, tracking packages programmatically, customs forms, carrier accounts (USPS/UPS/FedEx/DHL/ePost Global), scan forms, pickups, shipping insurance, or webhooks for shipping events. Also trigger on phrases like "create a shipping label," "buy postage," "rate a parcel," "verify an address," "international shipment," "commercial invoice," "Luma rate shopping," "UPS DAP," "DHL eCommerce," or any task involving the `@easypost/api` Node.js SDK or REST endpoints under `api.easypost.com/v2`. Optimized for Node.js/TypeScript but the REST patterns, field names, and carrier gotchas apply in any language.
Generates .NET/C# SDKs from OpenAPI specifications using the AutoSDK CLI tool (autosdk.cli). Use when the user wants to create a C# client library from an OpenAPI/Swagger spec, scaffold a new SDK project, regenerate existing SDK code, or customize generated .NET API clients.
[Pragmatic DDD Architecture] How to structure **Use Cases** using DDD and Railway-Oriented Programming (neverthrow Result types). Tailored for TypeScript + drizzle-orm + node-postgres stack. **Use whenever creating or modifying any Use Case class — even simple ones like "Exists" or "List" operations — to ensure type-safe error unions, proper transactional boundaries, Value Object-only contracts, auth-first patterns, and Result-based error handling.** Includes references to working examples (Create, List, Exists patterns). Depends on 'repositories' skill.
[Pragmatic DDD Architecture] Guide for creating DDD Repositories (Interfaces and Infrastructure). Use when creating repository contracts or implementing them using Drizzle ORM, Zod, and Postgres. Enforces completely typed transactions with Drizzle Transaction types (no 'unknown'), Result returns for Railway-oriented programming via neverthrow, and mapping pg node errors to domain errors. Fits our docker-compose / drizzle-kit standard testing workflow.
[Pragmatic DDD Architecture] Guide for creating strictly typed Domain validation and infrastructure errors. Use when handling or creating new errors to ensure they conform to the Railway-oriented programming model (neverthrow Result), TypeScript error branding, and constructor parameter constraints. Covers co-location rules vs. shared domain error usage.
ACF integration. Manage data, records, and automate workflows. Use when the user wants to interact with ACF data.
[Pragmatic DDD Architecture] Guide for creating DDD Entities and Aggregates. Use when defining new domain entities with business rules, private state, and getters. Covers entity instantiation via objects, integration with Value Objects, and the rule against using setters.
Enable developers to learn and use Chainlink Runtime Environment (CRE) quickly by referencing filtered CRE docs. Trigger when user wants onboarding, CRE workflow generation (in TypeScript or Golang or other supported languages), workflow guidance, CRE CLI and/or SDK help, runtime operations advice, or capability selection
Lightweight guidance for using the Upstash Redis RateLimit TypeScript/JavaScript SDK, including setup steps, basic usage, and pointers to advanced algorithm, features, pricing, and traffic‑protection docs.
