Recurring Hardware-Copilot (Natchpai) errors, by impact

  1. 1A 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 · Agent failure · 1 report66
  2. 2A 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 · Agent failure · 1 report66
  3. 3Eleven 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.ECAD · Agent failure · 1 report66
