A 200-line agent design treats the whole conversation as a single file

The author proposes an ultra-minimal agent setup: put the agent in an Alpine container, use the container itself as the sandbox, and store the entire conversation in a single file.
A roughly 200-line Python loop watches the file, detects when the human has finished typing, and lets the host talk to the agent by appending text directly. The whole API is basically cat and echo.
The question is whether this simplicity is a breakthrough or whether the design hides obvious problems that will show up after a couple of weeks of real use.
