foundations-distributed-systems SKILL.md skillA
foundations-distributed-systems from vasilyu1983/ai-agents-public is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add vasilyu1983/ai-agents-public/foundations-distributed-systems@v1.5Pins v1.5 in mdr.lock. Pin the fingerprint instead.

Designs consensus, quorums, leases, idempotency, and CRDTs. Use when facing split brain, fencing tokens, exactly-once claims, duplicate retries, stale reads, or leader flapping.
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
# Distributed Systems Foundations ## When to Apply **Apply when:** - 2+ nodes participate in a write or shared state (replication, consensus). - A retry, timeout or lost response can duplicate or drop an effect (idempotency, "exactly once"). - Two nodes may both act as primary (leases, fencing). - A consistency level is being chosen per feature (linearizable / causal / eventual). - Multi-AZ or multi-region failover and quorum sizing are being decided. **Skip, or route elsewhere, when:** - No coordination, retry/ambiguous-completion, durability or causal-order question exists. A single node or single writer alone is not a skip condition: a committed effect followed by a lost response can still be duplicated by a serial retry. - The question is throughput or latency under load: use foundations-queueing-theory. - The question is overload that persists after the trigger, retry storms or load shedding: use qa-resilience. - The question is availability or SLO budget: use foundations-reliability-theory. - The question is which verification tool to use (TLA+, model checking, proofs): use foundations-formal-methods. …

How to install
mdr add vasilyu1983/ai-agents-public/foundations-distributed-systems@sha256:ae570872a14466e5The line at the top of this page pins the label v1.5, 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.
