efitz-skills

A collection of Claude Code extensions for localization, security, and GitHub work. Localization means adapting software text for different languages and regions.

In plain words
What is it for?
It helps audit and update locale files, review concurrent code for race conditions, vet extensions before installation, choose backlog work, and create detailed GitHub issues.
Why use it?
It groups repeatable workflows for translation maintenance, plugin safety checks, concurrency reviews, and GitHub issue work.

Security

Grade A, and why

efitz-skills scanned grade A with 0 findings 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 yesterday.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 24 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.
