A Claude Code plugin for creating editable draw.io diagrams from Mermaid text or draw.io XML, with optional automatic layout. It can also export diagrams as PNG, SVG, or PDF while keeping the diagram data embedded.

Use it to generate flowcharts and other diagrams, arrange them automatically, export them to image or document formats, or open them through diagrams.net.

It removes the need to build diagrams manually in the draw.io editor for common generated workflows. It keeps exported files connected to their editable diagram source.

Security

Grade A, and why

claude-code 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 2d 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 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.
