patch-diff-analyzer

patch-diff-analyzer is a skill for Claude Code, Codex from zebbern/termstack. It costs 41 tokens per session (2,159 once invoked), scanned B, original, no licence file.

A tool for comparing compiled software files such as JARs and DLLs by reverse-engineering their changes.

In plain words
What is it for?
Use it to compare releases, investigate security fixes, or analyze patches in compiled binaries.
Why use it?
It helps reveal what changed between binary versions when source code is unavailable, including changes that may fix security problems.

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 B, and why

patch-diff-analyzer scanned grade B 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 2d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/analyze-diff.sh, scripts/decompile-dll.sh, scripts/decompile-jar.sh, …), 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 deletemediumDestructive command

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

rm -rf <workspace>/decompiled/*

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

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.
