Coding agent harness

A browser playground for the workshop. Your Anthropic key stays in this tab and is sent only to api.anthropic.com. It is not stored in this repository. The workspace is memory in the page, so nothing here can run a shell or change your computer.

Idle

OpenAPPA is off until you check the box. A public page cannot reach a runtime on your computer, so turning it on refuses the spawn unless that URL accepts this site.
