This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

snowbank-distributed-testing from snowbanksdk/foundationdb-dotnet-client is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

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

# SnowBank Distributed Testing & the Unified Test Journal

`SnowBank.Testing.Framework` is a **general-purpose** harness for multi-node integration tests: it spins up several in-process "virtual hosts" on a **simulated network** (no real sockets, no Docker), each with its own isolated DI container and ASP.NET host, so you can test how nodes talk to each other deterministically. It is **not** FoundationDB-specific — anything that runs on a `WebApplication` can be a host.

Its single most important diagnostic output is the **unified Timeline journal**: one chronologically-ordered, correlation-tagged event stream merging every host's logs, HTTP packets, and any library-registered traces. When a distributed test misbehaves, the journal is where you look first — and this skill is mostly about reading it and cranking its detail.

This skill is layer-agnostic. A specific layer's own probes (e.g. a state-synchronization layer's debugger surface, a BUGGIFY apply-barrier, replay/chaos fuzzing) live in **that layer's testing skill in the consuming repo**, not here.

How to install

The exact contents, by fingerprint
mdr add snowbanksdk/foundationdb-dotnet-client/snowbank-distributed-testing@sha256:71a2f8e8e1c07fd8

The line at the top of this page pins the label git:20260814.b952de4, 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.
