Recurring trace (mteichtahl) errors, by impact

  1. 1A quality bar reported 'Firmware matches the schematic: Met' on a project with no firmware because the check never read any firmware.ECAD · Agent failure · 1 report74
  2. 2An 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.ECAD · Agent failure · 1 report74
  3. 3The fab check could not see copper Gerbers on a board whose layers were renamed top_layer and bottom_layer, and the agent proposed renaming the layers in the board file after revision A was cut.ECAD · Agent failure · 1 report74
  4. 4The order estimate stood on a parts check from the day before while a later stage had added a soft-start switch, and nothing said so.ECAD · Agent failure · 1 report74
  5. 5A 2-layer board's release review said it had 20 layers because the fabrication step counted every board layer, including silk, mask and paste, instead of only copper layers.ECAD · Agent failure · 1 report66
  6. 6AgentCore Runtime refuses images over 2 GB, so KiCad 10, Blender, the FPGA toolchain and CalculiX had to move out of the agent image into a separate per-project function.MCAD · Agent failure · 1 report66
  7. 7An agent hardware tool's layout gate has the criterion 'The board fits its enclosure, or each clash is waived,' which 'has no check behind it yet.' The note picks build123d over FreeCAD and sets 0.5 mm board-to-wall defaults.MCAD · Agent failure · 1 report66
  8. 8An agent's schematic review kept the datasheet criterion not met because LCSC datasheet links now return an HTML viewer, not a PDF. Every part whose only datasheet link was LCSC had no datasheet.ECAD · Agent failure · 1 report66
  9. 9In an AI-driven board flow, the Overview estimate read US$26.83 to 83.04 for 10 boards because it took the newest parts check, which was a 2-line check of the display block alone (US$0.23). The chosen architecture's own 12-line check gives US$61.74 to 90.97.ECAD · Agent failure · 1 report66
  10. 10Waiving one KiCad footprint mismatch also waived the whole DRC criterion, letting any later DRC finding through unseen.ECAD · Agent failure · 1 report66
