yonsei-certificate-assistant

yonsei-certificate-assistant is a plugin for Claude Code from mrcha033/yonsei-skills. Its manifest loads nothing; the 4 skills it bundles cost 399 tokens per session together, scanned A, original, no licence file.

A cross-platform Yonsei certificate tool for Windows, macOS, and Linux. It checks the needed certificate choice and login once, then saves a free online-issued certificate as a local PDF.

In plain words
What is it for?
Selecting and issuing Yonsei certificates through the free online service and saving the resulting document as a PDF.
Why use it?
Getting a Yonsei certificate can involve choosing the right document, signing in, and handling the online print result. This guides that process and keeps the result as a file on the computer.

Security

Grade A, and why

yonsei-certificate-assistant 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 6d 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.

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.

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.

Contents

What it installs

The manifest is a name and a version. 4 skills travel with it, and installing the plugin installs all of them — 399 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
