You can list the uses of the available tools in the AGENTS. I keep my agents on a tight leash, and self-extension runs counter to this. I would not my agent to spontaneously develop the ability to tap my bank account, for example.

The Deno sandbox is the answer here — network access is restricted to an allowlist, and the execution environment has scoped permissions. The agent builds tools within those constraints, it can't reach anything you haven't explicitly allowed
