Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install secure-file-uploads-storage

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent designs file uploads: presigned URLs for direct upload, multipart uploads for large files, streaming instead of buffering, type checks by file bytes and sanitised filenames. It also explains how to limit the spread of presigned URLs.
