Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install server-file-upload

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 sets up multipart reception (Multer for Express, UploadFile for FastAPI, MultipartFile for Spring), checks the real file type beyond the MIME type and sets size limits. You get a secure upload endpoint, ready to forward to storage.
