Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# ArchLang

> A deterministic DSL and compiler for floor plans: write (or have an LLM write) `.arch` source and it compiles to SVG/DXF/PDF with linting and geometric validation — diffable, version-controllable, reproducible.

This file follows the [llms.txt](https://llmstxt.org/) convention: a concise, machine-readable map
of the project for large language models and AI agents.

How to install

The exact contents, by fingerprint
mdr add chanmeng666/archlang/llms.txt@sha256:d5b5a06ba57743c4

The line at the top of this page pins the label git:20261023.a9254d6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
