shapeitup

A plugin marketplace listing for ShapeItUp, a scripted computer-aided design toolkit. It lets agents create 3D geometry in TypeScript and export STEP or STL files, with optional live preview in Visual Studio Code.

In plain words
What is it for?
Creating or modifying shape files, checking geometry and collisions, and exporting models for CAD workflows.
Why use it?
It describes a way to produce and validate programmable 3D models from agent-written scripts.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

shapeitup 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.
