A computer-aided design tool for drawing floor plans, buildings, and manufactured parts in 2D or 3D. It can export drawings, 3D meshes, and IFC files, a format used for sharing building information with construction software.

Use it to draft floor plans, model buildings or parts, render previews, measure geometry, validate designs, and export DXF, SVG, STL, GLB, OBJ, or IFC files.

It lets a coding agent create and check technical designs through written commands instead of requiring manual CAD work for each change.

Security

Grade A, and why

modulor 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.

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.
