php-modernization

php-modernization is a skill for Claude Code, Codex from dirnbauer/typo3-skills. It costs 102 tokens per session (1,166 once invoked), scanned C, original, no licence file.

A guide for updating PHP code to newer PHP 8.1–8.5 features and common PHP coding standards.

In plain words
What is it for?
Use it when modernizing PHP, improving type safety, or working with DTOs, enums, readonly properties, strict types, and property hooks.
Why use it?
It helps make older PHP code safer, more consistent, and easier to check with tools such as PHPStan, Rector, and PHP-CS-Fixer.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

php-modernization scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/_common.py, scripts/introspect.py, scripts/modernize_loop.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- Never trust a warm PHPStan cache after vendor change: `rm -rf /tmp/phpstan-* var/cache/phpstan` first.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Files

What ships with it

32 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
