This skill exists so those adjacent concerns stay out of scope and the review stays focused on the cross-cutting, org-level decision: should this architectural change be approved, and on what terms.</p>\n<h2>When to use</h2>\n<p>Use this skill when the user asks to:</p>\n<ul>\n<li>review a proposal to adopt a new frontend framework, library, or build tool,</li>\n<li>resolve two teams solving the same problem with different primitives (state management, routing, styling),</li>\n<li>redraw a monorepo/polyrepo module boundary or ownership line,</li>\n<li>review a rendering-strategy change (CSR to SSR, SSR to SSG/ISR/streaming/PPR),</li>\n<li>audit an existing codebase for architectural entropy before a scaling or hiring push.</li>\n</ul>\n<p>Do not use this skill for:</p>\n<ul>\n<li>implementation-level state-management review — route to <code>state-management-decision-review</code>,</li>\n<li>routing/navigation-specific review — route to <code>routing-navigation-review</code>,</li>\n<li>API-contract or data-fetching review — route to <code>api-integration-contract-review</code>,</li>\n<li>SSR/hydration mechanics debugging — route to <code>ssr-hydration-streaming-diagnosis</code>,</li>\n<li>responsive/visual UI design review — that needs a design-system/visual skill, not architecture review.</li>\n</ul>\n<h2>Context7 Documentation Protocol</h2>\n<ul>\n<li>Before evaluating any version-sensitive technical claim in the proposal (e.g., \"Next.js Partial Prerendering lets us do X,\" \"React 19 Suspense enables Y\"), call <code>resolve-library-id</code> for the exact library, then <code>query-docs</code> against the repo's confirmed version — read <code>package.json</code> first to confirm the installed major version before trusting a claim about API availability.</li>\n<li>Matched library IDs for this skill's default grounding: React is <code>/reactjs/react.dev</code>, Next.js is <code>/vercel/next.js</code>. Resolve fresh for any other framework named in a proposal (Angular, Vue, SvelteKit, etc.) rather than assuming these two cover every case.</li>\n<li>Never approve a version-sensitive technical claim without Context7 verification. If Context7 is unavailable, mark the claim <code>documentation-based — unverified this session</code> in the verdict and require the proposer to confirm the claim before final approval.</li>\n<li>Documentation proves what a framework <em>supports</em>; it does not prove the proposal's specific repo can adopt it safely. Pair every Context7-grounded capability claim with a repo-evidence check (actual installed version, actual existing patterns) before treating it as settled.</li>\n</ul>\n<h2>Lean operating rules</h2>\n<ul>\n<li>First classify the proposal: new capability, migration of an existing capability, or boundary redraw. Do not evaluate a migration as if it were greenfield.</li>\n<li>Check for an existing in-repo equivalent before evaluating the proposal on its own terms. A proposal that duplicates a capability the repo already solves is a duplication defect regardless of how well-argued the new approach is.</li>\n<li>Require at least two alternatives with tradeoffs before treating a single-option proposal as reviewable. A proposal with no alternatives considered is not ready for an architecture verdict — send it back.</li>\n<li>Default against \"rewrite\" framing. If an incremental strangler-fig or boundary-first path exists, require it over a big-bang rewrite; do not accept \"the codebase is too messy to migrate incrementally\" without the proposer demonstrating why.</li>\n<li>Treat accessibility and security posture as first-class, blocking review criteria — not items to defer to a follow-up ticket. An architecture proposal silent on a11y/security is incomplete, not merely imperfect.</li>\n<li>Treat Core Web Vitals budget impact as mandatory for any rendering-strategy change; a proposal with no stated LCP/INP/CLS impact (lab or field) has not been evaluated for its primary tradeoff.</li>\n<li>Never fabricate a performance or vitals number without a stated measurement source; label estimates <code>inference, not measured</code> and require the proposer to supply lab or field data before final approval.</li>\n<li>Never execute, build, or run application code as part of this review; this is a static-review skill (Read/Grep/Glob only) — verdicts are based on document, code, and config evidence, not live measurement you generate yourself.</li>\n<li>Flag any architecture proposal that stores secrets or tokens in client-reachable bundles or build-time-inlined env vars, allows postinstall scripts from unpinned/unaudited dependencies, or introduces a CSP-incompatible pattern (<code>unsafe-eval</code>, dynamic <code>Function()</code>) as a blocking finding, not a note — this cannot be approved-with-conditions into a later cleanup.</li>\n</ul>\n<h2>References</h2>\n<p>Load these only when needed:</p>\n<ul>\n<li><a href=\"references/workflow-and-output.md\">Review workflow and ADR output contract</a> — use for the step-by-step review procedure, the approve/approve-with-conditions/reject decision tree, and the required ADR-format output shape.</li>\n<li><a href=\"references/rendering-topology-and-budgets.md\">Rendering topology and cross-cutting budgets</a> — load only when the proposal changes rendering strategy (CSR/SSR/SSG/ISR/streaming/PPR) or when Core Web Vitals, a11y, or security posture needs grounding against current framework/WCAG guidance.</li>\n</ul>\n<h2>Response minimum</h2>\n<p>Return, at minimum:</p>\n<ul>\n<li>the architectural change and files/modules/teams in scope,</li>\n<li>duplication check result (existing in-repo equivalent found or none),</li>\n<li>every version-sensitive claim labeled <code>Context7-verified</code> or <code>documentation-based — unverified this session</code>,</li>\n<li>verdict (approve / approve-with-conditions / reject-with-reasoning) with the specific unresolved conditions if any,</li>\n<li>rollback or incremental-migration path referenced explicitly,</li>\n<li>open questions the review could not resolve from available evidence.</li>\n</ul>\n","files":[{"path":"metadata.json","sizeBytes":1537,"isText":true},{"path":"references/rendering-topology-and-budgets.md","sizeBytes":6684,"isText":true},{"path":"references/workflow-and-output.md","sizeBytes":5531,"isText":true},{"path":"SKILL.md","sizeBytes":6426,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
