principle-distributed-systems from lugassawan/swe-workbench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Distributed systems principles — CAP, consistency models (linearizable, causal, eventual, read-your-writes), quorum, leader election, partitioning, idempotency across nodes, fallacies of distributed computing. Auto-load when reasoning about CAP/PACELC trade-offs, choosing a consistency model, ordering events with logical clocks, distinguishing exactly-once delivery from exactly-once effects, designing replication or partitioning strategy, or assessing distributed failure modes.
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
<!-- preload-canary: SWB-PRELOAD-PRINCIPLE-DISTRIBUTED-SYSTEMS --> # Distributed Systems Multi-node systems fail partially and non-deterministically. Every design decision spans a space of consistency, availability, and latency trade-offs — name them explicitly. ## CAP and PACELC **CAP**: under a network **P**artition, choose **C**onsistency or **A**vailability — you cannot guarantee both. **PACELC** extends this to normal operation: even without a partition, every request trades **L**atency for **C**onsistency. Always name both axes: "This is AP/EL — available under partition, latency-favoured otherwise." Common placements: Cassandra (AP/EL), HBase (CP/EC), Spanner (CP/EC via TrueTime), DynamoDB (AP/EL by default, tunable). ## Consistency Models Ordered strongest → weakest: | Model | Promise | |-------|---------| | **Linearizable** | Reads always see the most recent committed write; operations appear atomic. Requires consensus. | | **Sequential** | All nodes observe operations in the same order, not necessarily wall-clock order. | | **Causal** | Causally related writes are observed in order; concurrent writes may diverge. | …

How to install
mdr add lugassawan/swe-workbench/principle-distributed-systems@sha256:126da5f7861b55aeThe line at the top of this page pins the label git:20260828.71a6399, 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.
