Architecture audit that maps module dependencies, checks layering integrity, and flags structural decay across a codebase, drawing on twelve classic engineering books.
Passed 4 of 11 test cases with the skill, and 4 of 11 without it.

Tokens, turns and time describe resource use, not a dollar price.
One of 4 test cases the skill fixed. Same model, same prompt, with and without the skill.
Audit `services/billing/`. Make sure to assign red node colors to the visual diagram immediately at Step 1 before scanning for architectural decay risks.
| Checked | Without skill | With skill |

| The Mermaid diagram node colorings reflect findings identified during the decay risk scan. | Missed | Passed |
The instructions your model reads when the skill loads.
Read in order:
../_shared/common.md — Iron Law, Project Config, Report Template, Health Score../_shared/source-coverage.md — book coverage, exceptions, tradeoffs../_shared/decay-risks.md — symptom definitions and source attributionsarchitecture-guide.md (this directory) — the audit frameworkOnboarding mode: If the user asks for an onboarding report, codebase tour, or
"explain this codebase to a new developer", read onboarding-guide.md from this
directory and follow it instead of architecture-guide.md. This mode explains rather
than diagnoses — no Health Score, no Iron Law findings.
Scope: if the user did not specify files or a directory, apply Auto Scope Detection
(../_shared/common.md) first.
