A 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.
Recurring agent failure issue in trace (mteichtahl)
What engineers report
A recurring agent failure problem in trace (mteichtahl) that mostly hits the electrical engineer.
Failure pattern: agent / failure
Analyst note
From the Grok pain-radar digests, Nov 7-8 2026 (Nov 7 8:41 PM ET through Nov 8 7:41 AM ET digests plus the Haitch overnight edition). Verified live 2026-11-08: issue/PR read; title and state confirmed.
What it costs a team
Modeled annual cost
$30,000
For a team of 5
Prototype delay
3 days
Modeled schedule slip per occurrence
Time lost
240 min
Per engineer per month, about 1 incidents
How the cost is modeled
240 min/month × 5 engineers × 12 months = 240 hours × $125/hour = $30,000

Evidence
More recurring errors in trace (mteichtahl)
- A quality bar reported 'Firmware matches the schematic: Met' on a project with no firmware because the check never read any firmware.ECAD · impact 74
- 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.ECAD · impact 74
- The 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 · impact 74
- The 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 · impact 74
- AgentCore 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 · impact 66
- An 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 · impact 66
