Architecture SKILL.md skillA

Architecture from nxtg-ai/forge-plugin is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add nxtg-ai/forge-plugin/Architecture@git:20260715.857b62e

Pins git:20260715.857b62e in mdr.lock. Pin the fingerprint instead.

Clean Architecture, Domain-Driven Design, and backend system-design guidance: organizing a codebase into layers with the right dependency direction, choosing structural design patterns (Repository, Strategy, Observer, Command, DI), applying DDD tactical patterns (entities vs value objects, aggregates), designing REST resources and status codes, persistence (unit-of-work, N+1), caching, domain events, layered error handling, and recording decisions as ADRs. Use when designing a new system or…

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

# Architecture & System Design

**What this skill is**: reusable, language-agnostic guidance for structuring a
codebase — Clean Architecture layering, the dependency rule, the structural design
patterns that keep boundaries clean, and the ADR format for recording decisions.

**What this skill is NOT**: a description of the shipped NXTG-Forge implementation.
The real forge repos are polyglot (Rust orchestrator, Node governance MCP, React
UI) — for their actual internals read the repo `CLAUDE.md` files, not this skill.
The examples below are illustrative reference patterns you apply to *a* project,
shown in Python as one concrete language.

---

## Clean Architecture in one rule

**Dependencies point inward. Inner layers know nothing about outer layers.**

How to install

The exact contents, by fingerprint
mdr add nxtg-ai/forge-plugin/Architecture@sha256:9112ad100ae462d8

The line at the top of this page pins the label git:20260715.857b62e, 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.
