What is excalidraw-diagram?

A diagram tool for creating and editing Excalidraw drawings from written descriptions or code. Excalidraw is a web-based whiteboard for hand-drawn-style diagrams.

Use it for architecture diagrams, flowcharts, dependency views, and other technical whiteboard drawings.

It turns a plain-language request or code structure into a visual diagram, reducing the need to draw system relationships manually.

Security

Grade A, and why

excalidraw-diagram 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 4d 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.

What it installs

The manifest is a name and a version. 1 skill, 1 command, 1 agent travel with it, and installing the plugin installs all of them — 597 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.
