This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
foundationdb-advanced-layers from snowbanksdk/foundationdb-dotnet-client is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Advanced engineering for sophisticated FoundationDB layers with the .NET client (FoundationDB.Client / SnowBank) — the cluster model and transaction lifecycle (proxies, resolvers, tlogs, storage servers, the sequencer/version clock), latency/throughput optimization (batching reads with GetValuesAsync / Task.WhenAll, removing round-trip dependencies, snapshot reads), high-contention avoidance, and distributed patterns (change feeds, version-stamp logs, watch fan-out, version-as-clock leases…
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
# FoundationDB .NET — Advanced Layer Engineering This is the *advanced* tier. The **`foundationdb-keys-and-layers`** skill (key encoding, subspaces, the `IFdbLayer<TState>` pattern) and **`foundationdb-transactions`** skill (retry loop, idempotency, atomics, watches) are prerequisites — this skill assumes them and explains the *why* underneath, plus the patterns for performant, distributed, multi-node layers. A fully worked, compile-checked reference for everything in §5–§6 lives in [`samples/SkillValidation/BookStore.cs`](../../../samples/SkillValidation/BookStore.cs) + [`BookStore.ChangeFeed.cs`](../../../samples/SkillValidation/BookStore.ChangeFeed.cs). --- ## 1. The cluster model — how a transaction is actually processed *(FoundationDB's published architecture; the constraints below fall out of it directly.)* | Role | Responsibility | |---|---| | **Coordinators** | Small Paxos group; elect the cluster controller, hold the cluster file. Clients bootstrap here. | | **Cluster Controller** | Singleton; recruits/monitors all other roles, drives recovery. | …

How to install
mdr add snowbanksdk/foundationdb-dotnet-client/foundationdb-advanced-layers@sha256:40baf95b57224908The line at the top of this page pins the label git:20260809.f7377d4, 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.
