Deep Hotwire (Turbo, Stimulus, Hotwire Native) mental models, decision frameworks, and internals-informed debugging for Rails apps. Use whenever working with Turbo Drive/Frames/Streams, Morphing, ActionCable broadcasting, Turbo Cache, Stimulus controller design, Hotwire Native (iOS/Android, Path Configuration, Bridge Components), system testing Hotwire features, migrating legacy apps to Turbo, or debugging Hotwire behavior. Triggers on "Turbo Frame not updating", "Content missing", "morphing wipes my form", "broadcast not arriving", "flaky system test", "add Hotwire to legacy app", "wrap app with Hotwire Native", or any Turbo/Stimulus/Hotwire design decision.
A Rails-focused spec-driven development workflow for building features with AI agents. Use this skill when users want to plan features, write specs, create task breakdowns, or generate implementation prompts for Rails apps. Triggers on "sdd", "spec-driven", "shape spec", "create tasks", "initialize SDD", "feature planning", "implementation prompts", or any request to systematically plan and implement a Rails feature. Also triggers when moving from MVP documentation to implementation planning.
Create comprehensive MVP documentation for Rails applications. Use this skill whenever a user describes a new app idea, wants to explore a SaaS concept, needs competitor research, or is starting a new project from scratch — even if they don't explicitly say "MVP". Triggers on "I have an idea for...", "I want to build...", "help me plan...", "research competitors for...", "create a business plan for...", "design a brand for my app", "set up Claude for my Rails project", "bootstrap an app", or any request to plan, research, or document a new application concept.
Drive a running local Rails dev server from the terminal instead of a browser — log in (incl. OTP/magic-link codes read straight from the dev log), submit ERB forms with correct CSRF tokens, trigger and inspect Turbo Stream responses, and trace each request through the development log by request id. Ships an optional agent-browser (or Playwright) layer for the JS-dependent residual — screenshots, visual-regression diffs, waiting on Turbo events or DOM conditions, Stimulus controller introspection, and console/error capture. Use whenever exercising or debugging a Rails app's UI from the shell with curl instead of a browser — verifying a server-rendered turbo-stream, reading OTP/verification codes from the log, following an authenticated session, tracing what a request did, screenshotting a page or Turbo Frame, waiting for a broadcast to land, or inspecting Stimulus state. Especially apt for ERB + Hotwire apps with minimal JavaScript; bridges a logged-in session (storageState) between curl and a real browser so
Manages workspaces and memories in the Recuerd0 platform via the recuerd0 CLI. Use PROACTIVELY after architectural decisions, debugging sessions that resolved an issue, when the user states a strong preference, when a non-obvious discovery is made, or at the natural end of a focused working session. Also handles explicit save, search, version, and organize requests.
Simplifies and refines Ruby on Rails code following 37signals patterns and the One Person Framework philosophy, while preserving exact functionality. Focuses on recently modified code unless instructed otherwise. Use this skill when simplifying or refactoring Rails code, reviewing recently written Rails code for 37signals/vanilla-Rails conformance, or when asked to make Rails code more vanilla. Triggers on "simplify this", "refactor to 37signals", "make this more vanilla Rails", removing service objects, thinning fat controllers, converting boolean state columns to records, or CRUD-ifying custom controller actions.
Apply opinionated StimulusJS best practices from betterstimulus.com. Use this skill whenever writing, reviewing, debugging, or refactoring Stimulus controllers. Triggers when user asks to write, fix, or review a Stimulus controller, asks about data-controller, data-action, data-target, data-values, outlets, lifecycle callbacks, state management in Stimulus, Hotwire patterns, or Turbo and Stimulus integration.
Build consistent, accessible UIs in Rails using maquina_components. Use this skill whenever implementing UI for features, creating views, building forms, designing layouts, or reviewing UI specs. Triggers on view creation, UI implementation, form building, layout design, or mentions of maquina_components.
