I built a Claude Code skill that reconstructs historical monuments in 3D, stone by stone

I built something a little different from the usual productivity and coding skills.
It's called Monument.
The idea is simple: give Claude Code the name of a historical building, and it researches its history, reconstructs its architecture, and generates an interactive 3D model showing how it was built over time.

For example:
/monument Leaning Tower of Pisa, Italy

Claude then:

Researches the building's history using historical sources.
Finds its real footprint and architectural dimensions.
Identifies the different construction phases.
Generates the building using procedural 3D geometry.
Creates an interactive timeline where you can watch the monument being built, piece by piece.
Compares the result against reference photographs to improve accuracy. What makes this different from simply asking AI to generate a 3D model?

The goal isn't just visual generation.
Every construction phase is dated and sourced. The geometry is based on actual building measurements where available, and uncertain details are identified rather than presented as historical facts.

The entire experience runs locally using Three.js.
I've already created interactive reconstructions of the Leaning Tower of Pisa, the Eiffel Tower, and the Colosseum.

Try the interactive:
demos

Install the skill:

npx skills add Gleaming0427/monument

It also supports Codex, OpenCode, and Antigravity.
The project is completely free and open source (MIT).

Link github: GitHub

One limitation worth mentioning: detailed reconstructions can take 30–90 minutes, and the first result often needs refinement.
I'm sharing this because I'd love to see what other Claude Code users can build with it.

What monument should I try next?

I built Repoweek to turn READMEs into animated launch pages and video trailers

A README explains your project. But when you want to share it, you often need a landing page, a short video, and an image for social media.
I built Repoweek to help generate those assets from information already in your repository.
It’s an open-source skill for Claude Code, Codex, and Cursor.

What it creates

An animated landing page in a self-contained HTML file.
A video trailer exported as MP4 and GIF.
A social card for link previews and sharing. Watch the live demo

Getting started

Install the skill:
npx skills add Gleaming0427/repoweek
Then ask your coding agent:
Use repoweek to make a launch page and a trailer for this repo.
The agent reads your README and relevant project files, then prepares a JSON specification describing the content. Repoweek’s scripts render the page and export the media.
The output is yours to edit and host.

How it works

Repoweek separates writing the content from rendering it.
Your coding agent prepares the story: what the project does, its features, installation instructions, and demo content. The renderer turns that specification into HTML and animations.
For video export, a local browser captures the trailer frame by frame, and ffmpeg encodes the result.
The renderer has zero npm dependencies. Rendering requires Node.js 18 or newer; video export requires Node.js 22 or newer, Chrome or a compatible browser, and ffmpeg.

Customization and current limits

There are six theme presets and three trailer formats:
landscape, portrait, and square. You can also edit the generated JSON to change the copy, colors, and scene order.
The current trailers use animated text and code. They don’t include voice-over, background music, or screen recordings.
You should review the generated content before publishing, especially installation commands and claims about your project.

I’d love feedback

Would you use this to present your own side project? What would you change before sharing the output?
If you try it, I’d love to see what you create. And if you find it useful, a GitHub star is appreciated ⭐
