Eleven bug fixes in the schematic and PCB inspection tools an agent plugin uses to read KiCad files. All the 1.1 tests passed, but the bugs lived in cases the tests did not cover or covered with fixtures KiCad never writes. The worst gave wrong data: pins came from the wrong symbol definition, every pin was listed twice on symbols with an alternate body, and no via had a type, so an agent reading those outputs would reason confidently from bad facts.

Analyst note
From the Grok pain-radar digests, Nov 11-12 2026 (Nov 11 8:41 AM ET through Nov 12 5:41 AM ET digests plus the Haitch editions). Verified live 2026-11-12: 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

More recurring errors in Hardware-Copilot (Natchpai)
- A Claude skill for inspecting PCBs reported wrong pad positions on back-side parts and flagged every net on KiCad 10 boards as undeclared. pcb-inspect negated the X of pads on B.Cu even though KiCad already stores them flipped, and KiCad 10 boards with no net table had every net flagged as missing a declaration.ECAD · impact 66
- A schematic inspection tool an AI copilot relies on swapped pins 1 and 2 on mirrored parts at 90 and 270 degrees, and treated a global label and a same-named power symbol as separate nets. The fix applies the mirror after the rotation, joins those nets, and finds power symbols by their power flag instead of the library name.ECAD · impact 66
