+> **Rebuild:** this agent is being rebuilt as [`microscope_agent/`](https://github.com/kyu-softmatter/soft-matter-agents/tree/main/microscope_agent) in [soft-matter-agents](https://github.com/kyu-softmatter/soft-matter-agents), the four-agent system (microscope, simulation, librarian, bridge).
+
 An agent that turns a research goal into a microscope configuration that is
 checked against what the instrument can physically do — and refuses when the
 evidence for a setting does not exist.
