Each dot is a live Dynamic Worker — click any green dot to open its endpoint

Your Worker — trusted boundary

threadId: thread_8x7k2mNpQr_SENSITIVE

Secret credential — held server-side, never injected into sandbox

env.LOADER.load({

globalOutbound: null, // no internet

env: { MAIL: mailContext } // capabilities only

})

▼ injects capabilities, not secrets

Dynamic Worker Sandbox — AI Agent

Agent receives the MailContext toolbox:

env.MAIL.getContent() env.MAIL.sendReply(msg) env.MAIL.label(name)

⚠ env.MAIL.threadId → inaccessible via RPC

✗ fetch("https://...") → blocked — globalOutbound: null

Click the button to load agent code into an isolated Dynamic Worker and execute it.
