PHP Modernization Skill

Expert patterns for modernizing PHP applications to PHP 8.x with type safety, PSR / PER-CS compliance, static-analysis tooling, and Symfony-grade architecture. The skill ships an agent contract — a small set of executable tools that emit machine-readable verification reports, archetype profiles, and fix-loop transcripts.

Compatibility

This is an Agent Skill following the open standard originally developed by Anthropic and released for cross-platform use.

Supported platforms:

  • Claude Code (Anthropic)
  • Cursor
  • GitHub Copilot
  • Other skills-compatible AI agents

Skills are portable packages of procedural knowledge that work across any AI agent supporting the Agent Skills specification.
