 # Changelog
 
+## 1.7.1 (2026-05-06)
+
+### Documentation
+- README's Programmatic Usage section now documents `runSitemapAudit` alongside `runAeoAudit`. Library users who called `runAeoAudit('https://example.com')` on the homepage missed per-page issues — duplicate singleton `@type`s, JSON parse errors, missing schema on individual templates — because those problems live on subpages. Calling out the scope distinction up front, with a concrete `crossCuttingIssues` / `affectedUrls` example, makes site-wide auditing the obvious choice when one is appropriate.
+- Schema mode in `skills/aeo/SKILL.md` now defaults to sitemap mode (`--sitemap --top-issues`) for site-wide schema requests, mirroring the same scope guidance for skill users.

 ## Programmatic Usage
 
+The library exposes two audit entry points. **Use `runSitemapAudit` for site-wide checks** — `runAeoAudit` only fetches the URL you pass it, so per-page issues like duplicate `FAQPage` blocks, JSON parse errors, or missing schema on individual templates are invisible if you call it on the homepage of a multi-page site.

+
+```ts
+import { runSitemapAudit } from '@ainyc/aeo-audit'
+
+const report = await runSitemapAudit('https://example.com', {
+  limit: 200,               // Max pages to audit (default 200, sorted by sitemap priority)
+  factors: ['schema-validity', 'structured-data'],  // Optional subset

+console.log(report.crossCuttingIssues) // Per-factor rollup with affectedUrls for every recommendation
+console.log(report.prioritizedFixes)   // Top 5 fixes ranked by site-wide impact
+```
+
+Each entry in `crossCuttingIssues[].topIssues` carries a `recommendation` plus the exact `affectedUrls` so you can attribute each problem to specific pages — e.g. "FAQPage duplicate" pointing at every blog post that has it.
+
 TypeScript declaration files are included automatically.

+Validity issues like duplicate singleton `@type`s and JSON parse errors are **per page**, so a homepage-only audit misses every subpage. Default to sitemap mode for site-wide schema requests ("audit my schema", "are my FAQ blocks valid?"); use single-URL mode only when the user names one specific page.
