What it does, in plain words

Every codebase has unwritten rules. "Pages never talk to the database directly." "Shared code never reaches back into the app." Nobody wrote them down, but the code follows them, until one day someone (or an AI assistant) breaks one without noticing.

Archprint reads a TypeScript project, finds the rules its code already follows, and shows you the proof for each one: how many files follow it, which files break it, and how sure it is. The rules you trust become automatic checks in the tools your team already runs, so a break is caught the next time lint runs (in your editor, a pre-commit hook or CI), not weeks later in review.

Think of it as a building inspector who surveys the house first and writes down how it was actually built, instead of handing you a rulebook from somewhere else.

generated with init, connected with wire, and removed with eject.

• For developers and tech leads: inferred, evidence-backed lint rules for ESLint and dependency-cruiser,

rules, with the evidence, before they write code.

• For teams using AI coding agents: Claude Code, Cursor and other agents can ask Archprint for the project's

• For anyone evaluating a codebase: a quick, honest picture of how a project is actually structured.

Your CLAUDE.md is guidance. Your lint rules are enforcement. Archprint closes the gap by generating the enforcement from patterns your codebase already demonstrates, so you adopt rules you can trust instead of authoring them by hand.

See it in action

The recordings below use archprint-demo, a small Next.js API whose routes reach the database only through a service layer.

1. Find the rules your code already follows. Each rule comes with its evidence.

2. See why one rule is trusted. The confidence check, step by step.

3. Turn the rules on, watch a break get caught, and remove it all again. Archprint writes its files, adds one line to your ESLint config, lint flags a route that imports the database directly, and eject restores your project exactly.

Try it yourself, nothing to install: open the demo in StackBlitz. The scan runs as soon as it opens, and the demo's README walks through enforcing a rule in ESLint, breaking it, and asking for the rules over MCP.
