php-code-injection

php-code-injection is a skill for Claude Code, Codex from blacklanternsecurity/red-run. It costs 74 tokens per session (2,890 once invoked), scanned A, original, GPL-3.0.

A guide to testing PHP code-injection flaws in which user input is evaluated as PHP code. It covers older and newer runtime features that can evaluate or create PHP functions.

In plain words
What is it for?
It is for authorized reviews of PHP applications that use eval, callbacks, assertions, or runtime function creation with untrusted data.
Why use it?
It helps distinguish direct PHP code execution from operating-system command injection or template injection, so the right weakness is tested.

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 A, and why

php-code-injection scanned grade A 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.

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.

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.
