A Claude Code and Codex plugin for organized, ongoing vulnerability research. Vulnerability research looks for security weaknesses and checks whether they can be realistically confirmed.

Use it for structured security research, including planning investigations, retaining useful findings, and validating suspected vulnerabilities.

It helps coordinate research over time by keeping track of memory, strategy, and validation. This reduces the need to organize those parts manually.

Security

Grade A, and why

proteus 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 today.

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.

What it installs

The manifest is a name and a version. 10 skills travel with it, and installing the plugin installs all of them — 518 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
