Deep-explore current codebase and register it as a Walnut repository. Produces a rich profile: what the project does, architecture overview, key components, tech stack, and common workflows. Use when user says "register repo", "add this repo", "/walnut-register-repo", or wants to create a Walnut repository profile for the current project.
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
# Register Repository
Explore this codebase and produce a rich, structured repository profile.
## Goal
Create a YAML file at `~/.open-walnut/repositories/{slug}.yaml` that genuinely captures what this project is, how it works, and how to work with it. Someone reading this profile should understand the project without opening a single file.
## How to explore
Start with a quick broad scan — directory structure, README, package manifest — to get the lay of the land. Based on what you find, decide what needs deeper investigation. Use sub-agents for parallel deep dives into areas you identify as important.
You decide the exploration strategy. A React SPA needs different investigation than a microservice or a CLI tool. Go where the interesting stuff is.
**Quality bar**: "A web application built with React" is useless. "Real-time collaborative document editor with CRDTs for conflict resolution, React frontend with ProseMirror, and WebSocket sync server" is what we want.
## Output Format
Write the YAML to `~/.open-walnut/repositories/{slug}.yaml`:
```yaml
name: Project Name
description: >-
1-3 sentences. Specific about what it does, not generic.
…Read the whole file at its exact version.
How to install
mdr add evanzhang008/open-walnut/walnut-register-repo@sha256:36a1a244474db780The line at the top of this page pins the label git:20260911.35d897a, 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.
