//
// Zero npm dependencies. Uses only node builtins.

## Filer å oppdatere

${fileList}

## For HVER fil

1. Les filen med Read
2. Bruk microsoft_docs_fetch på de endrede kilde-URLene listet over
3. Bruk microsoft_docs_search for supplerende info
4. Oppdater filen med Edit:
   - Oppdater "Last updated" til ${new Date().toISOString().slice(0, 7)}
   - Oppdater utdaterte fakta, priser, datoer
   - Bevar eksisterende struktur og seksjoner
   - Marker oppdatert innhold med "Verified (MCP ${new Date().toISOString().slice(0, 7)})"

## Etter alle oppdateringer

1. Kjør: node scripts/kb-update/build-registry.mjs --merge
2. Kjør: node scripts/kb-update/report-changes.mjs
3. git add skills/ scripts/kb-update/data/
4. git commit -m "docs(architect): weekly KB update — ${staleFiles.length} files refreshed

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>"
5. git push origin main

## Regler
- Aldri slett filer, kun oppdater
- Bruk Edit, ikke Write
- Bevar all eksisterende struktur`;
