Do not use it for greenfield architecture, direct code review, implementation, security auditing, API contract authoring, data-platform strategy, or migration execution.</p>\n<h2>Requirements</h2>\n<p>Git and a programming language runtime matching the target codebase. Mermaid-capable Markdown is useful for architecture diagrams. No purchased books or private source material are required.</p>\n<h2>Quick Start</h2>\n<p>Start with the workflow in <code>SKILL.md</code>, then load the relevant reference. For a health review, copy <code>templates/architecture-health-assessment.md</code>, fill the evidence ledger first, and keep recommendations in a separate section.</p>\n","files":[{"path":"evals/evals.json","sizeBytes":7529,"isText":true},{"path":"README.md","sizeBytes":2520,"isText":true},{"path":"references/architecture-characteristics-analysis.md","sizeBytes":3257,"isText":true},{"path":"references/coupling-modularity-and-decomposition.md","sizeBytes":3800,"isText":true},{"path":"references/data-ownership-and-workflow-analysis.md","sizeBytes":3025,"isText":true},{"path":"references/interface-extraction-pattern.md","sizeBytes":5864,"isText":true},{"path":"SKILL.md","sizeBytes":14489,"isText":true},{"path":"templates/architecture-health-assessment.md","sizeBytes":2573,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
