arch-check

Architecture conformance check: verifies an existing codebase against its declared architecture (VSA, Clean Architecture, DDD, Modular Monolith) — dependency direction, layer violations, module boundary leaks, and cycles — using token-cheap Roslyn MCP analysis. Invoke when: "check architecture", "architecture violations", "layer violations", "dependency direction", "module boundaries", "arch check", "is my architecture clean", "enforce architecture", "conformance check". For CHOOSING an architecture, use architecture-advisor instead.

# /arch-check

## What

Verifies that the code still matches the architecture it claims to have.
Architectures rot through small, individually-reasonable changes — a Domain
project that gains an EF Core reference, a module that reaches into a sibling's
internals, an endpoint defined outside the host. This workflow catches the rot
using project-graph and dependency analysis, not file-by-file reading.

Output: a violation report with severity, file:line evidence, and the concrete
fix — or a clean conformance pass.
