nw-sd-patterns from nwave-ai/nwave is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nwave-ai/nwave/nw-sd-patterns@git:20260406.b65a761Pins git:20260406.b65a761 in mdr.lock. Pin the fingerprint instead.

Core distributed systems patterns - load balancing, caching, sharding, consistent hashing, message queues, rate limiting, CDN, Bloom filters, ID generation, replication, conflict resolution, CAP theorem.
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
# Core Distributed Systems Patterns ## Load Balancing **Problem**: single server can't handle all traffic. **Approaches**: Round Robin (simple, ignores load) | Weighted Round Robin (accounts for capacity) | Least Connections (fewest active) | IP Hash (session affinity) | Layer 4/transport (IP/port, fast) | Layer 7/application (HTTP-aware, smarter) **Placement**: client-to-web | web-to-app | app-to-database **Trade-offs**: LB itself is SPOF -- use active-passive pair | session affinity complicates horizontal scaling -- prefer stateless servers | health checks critical ## Caching **Problem**: repeated DB reads are slow. **Strategies**: Cache-aside/lazy loading (app checks cache, fills on miss -- most common) | Write-through (write cache+DB simultaneously) | Write-behind (cache only, async to DB) | Read-through (cache fronts DB transparently) **Cache-aside pattern**: Read: `cache.get(key) -> hit? return : db.read -> cache.set -> return` | Write: `db.write -> cache.delete(key)` **Eviction**: LRU (most common) | LFU (skewed access) | TTL (time-based) …

How to install
mdr add nwave-ai/nwave/nw-sd-patterns@sha256:5f38b31c8a49d5e4The line at the top of this page pins the label git:20260406.b65a761, 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.
