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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

## ARCHITECTURE
### 1. Application Controller
Create a base `ApplicationController` that all controllers inherit from. Use it to share lifecycle hooks and utility methods across the app.
```js
// application_controller.js
import { Controller } from "@hotwired/stimulus";
export default class extends Controller {
// shared helpers, error handling, etc.
}
// custom_controller.js
import ApplicationController from "./application_controller";
export default class extends ApplicationController {
// specialized behavior
}
```
**When NOT to use inheritance:** Ask whether the shared behavior is a *specialization* ("is a") → use inheritance; a *role* ("acts as a") → use mixins; a *collaborator* ("has a") → use composition.
---
### 2. Configurable Controllers (Late Binding)
Never hardcode dependencies (CSS classes, selectors, IDs) inside controllers. Use the Classes API, Values API, or dataset attributes so controllers are reusable.
Bad:
```js
toggle(e) {

How to install
mdr add maquina-app/rails-claude-code/better-stimulus@sha256:33421e2c2e7fd6c8The line at the top of this page pins the label git:20260714.486d7e4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
