State-of-the-art software and system architecture rules (2026) for both building and auditing. Use when designing, building, refactoring, or extending system architecture — boundaries, DDD, hexagonal/clean architecture, event-driven design, CQRS, sagas, messaging, caching, sharding, multi-tenancy, resilience, scalability, 12-factor/cloud-native — AND when auditing existing architecture for quality (design review, anti-patterns like distributed monolith or shared database…

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

# SOTA Architecture (2026)

## Purpose

Dense, enforceable rules for software and system architecture: choosing styles,
drawing boundaries, surviving distributed systems, scaling state, and shipping
cloud-natively. One rule set, two modes — apply the rules while **building**,
or check code against them while **auditing**. All substance lives in `rules/`;
this file routes you to the right one.

## BUILD mode — designing or writing code

1. **Identify the decision surface.** Before writing code, list the architectural
   decisions in play (style, boundaries, sync/async, datastore, tenancy, caching).
   Use the index below to read the relevant rules files *before* committing to a
   design — minimum: 01 for any new system/service, 03 for anything crossing a
   network, 07 always (know what failure looks like).
2. **Default to boring.** Modular monolith, one database, sync calls within the
   deadline budget, queues only where semantics are async. Escalate complexity
   only when a rule's stated forces apply, and record it.
3. **Write the ADR first** for any Type 1 (hard to reverse) decision: context,
   decision, consequences (must include downsides), rejected alternatives. Put it
…

How to install

The exact contents, by fingerprint
mdr add martinholovsky/sota-skills/sota-architecture@sha256:d2fc5154cf626ff8

The line at the top of this page pins the label git:20261012.ae1b29b, 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.
