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

# ossrules.md

ossrules.md is a Modem-built reference library of real open-source agent instructions and skills.
This is the canonical project guidance; `CLAUDE.md` is a relative symlink to it.

## What we are building

Help developers write better instructions for coding agents by learning from
real projects. Readers should be able to find a relevant example, understand
what its instructions do, inspect the original source and supporting documents,
and borrow useful techniques for their own repositories.

The site earns trust through specific observations and accurate source context.
It is a reference library, not a leaderboard or a collection of generic AI advice.
Describe what a file does and why it matters; let readers judge whether it fits.

## Preserve the aesthetic

- Keep the reference-library feel: a scannable two-column directory on desktop,
  comfortable reading layouts, clear hierarchy, compact metadata, and generous
  enough spacing to make dense material approachable.
- Prioritize readable content over viewer controls and secondary metadata. Keep
  supporting detail available on demand. Use borders to clarify entries, tabs,
…

How to install

The exact contents, by fingerprint
mdr add modem-dev/ossrules/AGENTS.md@sha256:8040112b71416e04

The line at the top of this page pins the label git:20260918.a539028, 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.
