Marionette, our project addresses both statement 1 and 3. Marionette is a cli tool that lives on top of claude code and other ai agents, which monitors both the user and the agent. The user is monitorred for poor prompts, and marionette encourages the user to write more detailed ones. The agent is monitored for sycophancy, and marionette automatically stops the agent, then forces the agent to rerun, but with less sycophancy.
