An agent harness for KiCad boards. On one run, a worker "could not pass the brief's flags to kicad.fab. It renamed Gerbers to Protel extensions, could not clip silkscreen from mask, got one merged drill file with every hole marked plated, wrote an empty -NPTH.drl by hand, and dropped the .gbrjob." The fix adds the missing inputs, then checks after plotting that file names, the job file and plated vs unplated hole counts match the board. Anything not applied fails the run and the summary says not to send the package. The worker prompt now forbids renaming, editing or hand-writing fab files.
