Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install webcontainer-local-test-loop

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 turns a manually tested WebContainer host into a repeatable loop, separating file-tree tests from browser tests that need SharedArrayBuffer and real response headers. You get regression coverage you can run locally.
