Generate production-ready Saloon-based API integrations for Laravel projects including connector classes, request classes, readonly DTOs, service layer methods with comprehensive error handling, and complete Pest test suites. Use this skill when integrating external APIs using Saloon, creating API request/response handlers, adding new API endpoints to existing services, building API client wrappers for third-party services, or setting up API communication with proper error handling and testing. This skill applies when working on files in app/Services/Api/, app/DataTransferObjects/Api/, creating Saloon connectors and requests, implementing API service methods, or writing API integration tests.

This skill should be used when the user asks to "generate Rails code", "create a model", "create a controller", "add a migration", "write Rails tests", "set up background jobs", "configure Rails app", or discusses Rails conventions, best practices, ActiveRecord patterns, Hotwire/Stimulus, ViewComponent, RSpec testing, or Ruby on Rails development. Based on Evil Martians' AGENTS.md.

This skill should be used when the user asks about "Rails testing", "RSpec", "Minitest", "request specs", "system specs", "FactoryBot", "fixtures", "test coverage", "testing controllers", "testing models", "integration tests", or needs guidance on writing effective tests for Rails 7+ applications.

MUST invoke when encountering errors, bugs, test failures, or unexpected behavior - before any debugging action.

Write automated tests following a pragmatic, integration-focused philosophy. Use when writing tests for new features, writing tests for bug fixes, adding test coverage, or deciding what/how to test. Emphasizes confidence over coverage, real objects over mocks, integration over isolation, and simplicity over dogma.

Generate behavioral unit tests from functional specifications using PreDB/PostDB pattern. Use when user provides specs with PreDB/Workflow/PostDB structure or asks to write tests for a specification before implementation (TDD approach).
