Yesterday's morph-as-tool refactor leaves a gap. Once the agent can author tools, the next question is what those tools are written in — and whether compilers and VMs are themselves tools. They are. Which means the privileged layer is a design knob; here's how low you can turn it.
Most agent frameworks split decisions into agent-decidable tools and developer-decidable transitions. Collapse that split — make the transition itself a tool — and the agent can design new modes mid-conversation. A 700-line demo with a verification loop, plus an honest accounting of what's still missing.
The only way to catch what an agent did is to send another agent. A short story about scripted tests rotting under prompt drift, and the small twin we built to fix it.
