## What php-modernization does, in the publisher's words

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.

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
- Agent contract: a Python verifier (verify_php_project.py), orchestrator (modernize_loop.py), and cheap profiler (introspect.py). stable structured output (JSON with schema_version 1.0.0, SARIF 2.1.0, or JUnit XML), archetype detection, and machine-readable agent_actions[] recommendations downstream agents can act on without re-reading the prose references.
- Hard guardrails: five binding refusal cases enforced in SKILL.md (no readonly on Doctrine entities, no Rector without --dry-run, baseline shrink-not-delete, no blanket final on mock targets, no editing generated files).
