Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install untrusted-code-sandbox-deno

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 creates a Deno sandbox, runs processes, handles streaming input and output, and kills processes. Each sandbox runs in its own Linux microVM with a separate filesystem and network.
