The Sainte-Chapelle construct assembling itself

The first public release. Construct is an agent skill and toolkit that turns a description of a
real or fictional thing into an animated holographic model, in the Measured Light style: an AI
agent writes a short scene, and Construct checks it, builds it into one web page and reviews it.

What's included

  • Three modes, and the skill chooses. fast is one careful pass in about ten minutes;
    masterpiece runs rounds judged by an independent critic for named subjects whose likeness
    matters; unbounded keeps going without the round and time limits, only when you ask. When
    you don't name a mode, the skill picks one and tells you why before it starts.
  • An independent critic. In masterpiece mode a fresh model compares each new version with
    the best so far without knowing which is which, and only a better version is kept. You get a
    short report after every round.
  • Honest constructs. Every fact and part is marked as verified, user-supplied, inferred or
    decorative, and the provenance view (press P) shows which. Unknown facts are left out.
  • A check that repairs. Every problem comes back with where it is and how to fix it, and the
    agent repairs until the scene is clean.
  • One house style, Measured Light. Line light over smoked glass, built part by part on screen,
    with labels drawn only from facts. Models never choose the colours.
  • A drawing guide for detailed, sculpted constructs, and a check that warns when a main surface
    is drawn as a flat shape.
  • New shapes: lofted car bodies and a vehicle template, towers, roofs, facades, battlements,
    ribbed shells, measured terrain and a globe from coastline data.
  • An examples gallery of constructs made by Claude Opus, GPT-6.1 Sol and DeepSeek:
    https://rtmandreyev.github.io/construct/
  • Any agent, any model: Claude Code and Hermes skills, an MCP server, and a runner for any
    OpenAI-compatible model.

Install

git clone https://github.com/rtmandreyev/construct.git
cd construct
python3 construct_hologram/package.py --out dist

Then add dist/claude-code/construct to Claude Code (claude --plugin-dir dist/claude-code/construct)
or copy dist/hermes/construct into ~/.hermes/skills/, and ask in plain words: "make a construct
of a Leica M3". See the README and USING.md.

Requirements

Python 3.10 or newer, with no third-party packages. Review stills need a Chromium-family browser
you already have; videos need ffmpeg.

Known limitations

  • Glass is never tinted, and stills show the closed pose; open a construct in a browser to see it
    open.
  • No imported meshes, CAD or photogrammetry; a construct is built from Construct's own shapes.
  • One periodic motion per part.
  • Masterpiece mode in Hermes needs a higher helper-agent limit; see
    Troubleshooting.
  • Tested on macOS; review capture on Linux and Windows is untested.
