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.

Run an autonomous coding agent that builds applications from specifications. Use when asked to "build an app autonomously", "run autonomous agent", or "create application from spec".

Use when you need SVGs with selectable/customisable appearance: multiple palettes (WLILO / Obsidian / light), consistent typography, and repeatable agent-friendly pipelines. Triggers: svg theme, tokens, palette, WLILO, obsidian, design system, dark mode, diagram styling.

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.
