SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides concise, curated updates for language and framework changes so developers avoid introducing outdated APIs, deprecated patterns, and breaking behaviors when writing or updating Elixir, Phoenix, and LiveView code.

Core Features & Use Cases

  • Breaking-change summaries: Clear notes on behaviors that now raise, deprecated patterns, and required code adjustments for Elixir 1.19–1.20 and Phoenix 1.8.
  • API and tooling guidance: Lists of new stdlib APIs, mix and compilation changes, and updated project configuration practices.
  • LiveView & frontend patterns: Updated JS hook patterns, colocated hooks, portals, keyed comprehensions, and testing migrations to LazyHTML.
  • Use Case: Run a patch check before generating or refactoring code to ensure generated code uses the correct APIs, avoids deprecated constructs, and follows new compilation and LiveView conventions.

Quick Start

Ask the elixir-knowledge-patch to review your project and produce a prioritized list of code changes required to migrate to Elixir 1.20 and Phoenix 1.8 compatibility.
