Stop babysitting your agent. Architecture rules it can't ignore, checked on every change before it moves on.

A communication layer between you and your codebase: it keeps your AI coding agent talking in plain language — no jargon, no invented timelines — with one clear yes before anything irreversible.

Your agent hits a gap in the spec and guesses. Urd makes it stop and ask instead.

Per-file architecture rules for your coding agent. Markdown rules with a trigger DSL, verified on every commit by a local Ollama or paid API. Claude Code plugin, zero npm deps. The lighter sibling of Yggdrasil — reach for AutoReview when one rule on one file is enough.
