What to do

• Delete Blob-related vault tools:
  • packages/vercel/src/tools/vault-delete.ts
  • packages/vercel/src/tools/vault-glob.ts
  • packages/vercel/src/tools/vault-list.ts
  • packages/vercel/src/tools/vault-read.ts
  • packages/vercel/src/tools/vault-write.ts
• Remove vault tool exports from packages/vercel/src/tools/index.ts
• Remove any vercel/blob dependency from packages/vercel/package.json
• Remove vault tool references from packages/vercel/src/index.ts

Current Code

• packages/vercel/src/tools/vault-*.ts — 5 vault tool files
• packages/vercel/src/tools/index.ts — exports
• packages/vercel/src/index.ts — package exports
• packages/vercel/package.json — dependencies

Architecture Context

From #550 architecture decisions: Local-first (CRITICAL). No Blob, no DB, no Cache. Markdown files processed at build step. Vaults read from filesystem, not Blob storage.

Acceptance

• No vault-*.ts files in packages/vercel/src/tools/
• No vercel/blob in packages/vercel/package.json
• No vault tool exports in index files
• bun run build passes
