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

# AGENTS.md

ArchLang: a declarative language (`.arch`) that compiles to SVG floor plans. TypeScript, Node 18+,
npm-workspaces monorepo; the core (repo root, `@chanmeng666/archlang`) also runs in the browser.
Code and tests are the documentation; this file holds only what they cannot say.

```bash
npm run build         # core + CLI → dist/ (before typecheck:all, e2e)
npm run cli -- compile examples/studio.arch -o studio.svg
npm run check         # typecheck + lint + test-wiring + vitest (floor)
npm run check:drift   # generated artifacts == generator output (CI gate)
npm run typecheck:all # the only typecheck that compiles test/ and the workspaces
npm run docs:build    # after any docs/*.md edit
npm run gen:all       # every gen:* generator
```

## Hard rules

- `compile()` is pure, sync, deterministic: no I/O, time, randomness or Node APIs in `src/` outside
  `src/cli.ts`+`src/cli/`; environment via the `World` seam; numbers via `src/num-format.ts`; never
  mutate the memoised parse-stage `PlanNode` (clone). Zero runtime deps.
- User-source errors are returned as a `Diagnostic` (byte `span` + catalogued `E_*`/`W_*`), never thrown.

How to install

The exact contents, by fingerprint
mdr add chanmeng666/archlang/AGENTS.md@sha256:2936c1bcaa8b05ec

The line at the top of this page pins the label git:20261024.8988a9d, 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.
