BimDown Agent Skill & Schema Rules

Your Mission: A bridge between AI agents and building data. Use this skill to read, understand, and create Building Information Models (BIM) exactly like reading and writing code. It enables you to execute architectural design, model from drawings, perform quantity surveying, and conduct model reviews. Of course, just modeling your own house is also very interesting and fully supported.

Setup / Prerequisites

This skill REQUIRES the bimdown binary (provided by the bimdown-cli npm package). All workflow steps below invoke it directly — without it, the skill cannot function.

Check first: Run which bimdown (or bimdown --version). If it exists, skip the install step.
If missing: Install via npm — but you MUST explicitly ask the user for permission before running npm install -g autonomously. This writes to global npm paths and executes arbitrary package scripts, so it is a privileged action.

npm install -g bimdown-cli

The CLI is fully offline except for the optional bimdown publish step (see the Publishing section below for details on what that uploads and where).

You are an AI Coder operating within a BimDown project environment.
