Cover Stimulus controller fundamentals: lifecycle hooks, values and valueChanged callbacks, targets and target callbacks, outlets, action parameters, keyboard events, and controller architecture patterns. Prefer this skill when the request is primarily about Stimulus APIs and controller design independent of a specific Hotwire domain. Use hwc-forms-validation for form-specific workflows, hwc-navigation-content for Turbo navigation concerns, hwc-realtime-streaming for Turbo Streams/WebSocket patterns, hwc-media-content for media integrations, and hwc-ux-feedback for loading/progress/transition UX patterns.

Stimulus Fundamentals
Implement robust Stimulus controllers with clear lifecycle and state boundaries.
Core Workflow
- Define controller contract first: targets, values, outlets, actions, and expected lifecycle.
- Keep state transitions in value callbacks when reactive updates are required.
- Guard callbacks that can run before
connect()completes. - Use
connect()/disconnect()for setup and teardown symmetry. - Isolate DOM event handling from business rules; keep controllers composable.
Guardrails
- Prefer declarative action parameters over manual dataset parsing.
- Use outlets for controller-to-controller communication instead of private internals.
- Keep target callbacks idempotent; account for repeated connect/disconnect cycles.
- Use MutationObserver only when DOM-driven reactivity is required.
- Feature-detect browser APIs before exposing UI affordances.

Use when writing, reviewing, or debugging pure Ruby code — idiomatic patterns, modern 3.x+ features (pattern matching, Data.define, endless methods), error handling conventions (raise vs fail, result objects), memoization, and performance idioms. For Rails use rails-guides. For testing use minitest. For code style use sandi-metz-rules.

Use when stuck after multiple debug attempts and want to escalate to a stronger one-shot model (GPT-5 Pro, Opus, Gemini Pro) — packages a self-contained "oracle prompt" with Ruby/Rails project briefing, verbatim error, what-was-tried, constraints, and just-enough attached files. Triggers include "ask the oracle", "write a letter to GPT-5", "I'm stuck, draft a prompt for another model", "/tmp/letter.md".
