hex-agent turns a plain-language brief into a valid build of a real product. Hex Cluster is One Thousand Drones' modular 3D-printed hexagonal hardware, and its browser configurator already knows which parts fit where. The agent, built during the event, lets a Meta Muse model drive that configurator through its public window.hexAPI in a real browser tab: it reads the build, asks where parts fit, places them, reads every acceptance or refusal, revises, and ends with a share link, a parts list and a print pack, plus its own statement of which requirements it met, partly met or could not meet. The model chooses; the configurator's rules, collision check and our code decide the run. Briefs that would carry a child's weight, hold fuel or heat, or restrain a person are declined. On the frozen agent (git tag eval-final), Muse Spark 1.3 passed 14 of 18 held-out briefs on one pre-committed run (77.8%, Wilson 95% CI 54.8 to 91.0) and 173 of 180 development runs. Every run is traced; the 5,128 traces, grader, data pack and paper are in the repo.
