  "title": "Vercel Sandbox now supports FUSE-based filesystems",
  "why_included": "Vercel Sandbox can now mount FUSE filesystems — S3 buckets, network shares, any FUSE driver — as POSIX paths, so sandboxed agent code can stream remote data without copying it in first.",
  "summary": "**The gist** Vercel Sandbox now supports **FUSE**, so a running sandbox can mount remote storage as a regular path — **S3 buckets** via **Mountpoint for S3**, network filesystems, or any FUSE-compatible driver. The documented flow installs the mount tool inside the sandbox, creates a mount point, and passes AWS credentials through environment variables.",
  "practical_implication": "**Why it matters** Sandboxes are where agent-generated code tends to execute, and mounting object storage as a **POSIX path** means that code can stream **large datasets** straight from remote storage, run tools that expect local files against remote sources, and **share state across Sandboxes** through a common filesystem — no copy step before every run.",
