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

# Puffo Test Admission Rules

Every test must name the future production regression that would make it fail.
If deleting the test leaves no silent failure path, delete the test.

A new test must protect at least one of these:

1. A reproduced bug. Observe the test fail on the broken implementation, then
   pass after the fix. Describe the mechanism in behavioral terms.
2. A derived property or protocol invariant, such as ordering, idempotency,
   routing, encryption boundaries, lifecycle transitions, or retry semantics.
3. Critical bookkeeping that can silently drift, such as field propagation,
   serialization compatibility, registry completeness, or config migration.
4. A cross-component workflow whose failure cannot be detected at a smaller
   boundary. Keep these integration cases few and representative.

Do not add:

- Happy-path assertions that mirror an implementation line.
- Multiple cases guarding the same failure mode.
- Probabilistic concurrency stress that does not fail on the broken code.
- Test-only production APIs that expose private state without a real runtime
  use case.
- Verbatim prompt snapshots unless exact text is itself a public contract.

How to install

The exact contents, by fingerprint

mdr add puffo-ai/puffo-agent/tests/AGENTS.md@sha256:d5ace142ec02cdaa

The line at the top of this page pins the label git:20260811.0d9f44d, 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.
