The first write to a KiCad 9 board upgrades it to KiCad 10 format, so the ECO compare flagged format-only changes as unexpected. A correct one-part change failed with 72 entries while a track-by-track check found none of 815 tracks and vias moved.
Recurring agent failure issue in kicad-cli-extended (Hybirdss)
What engineers report
A recurring agent failure problem in kicad-cli-extended (Hybirdss) that mostly hits the electrical engineer.
Failure pattern: agent / failure
Analyst note
From the Grok pain-radar digests, Nov 8-9 2026 (Nov 8 8:41 AM ET through Nov 9 6:41 AM ET digests plus the Haitch editions). Verified live 2026-11-09: 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 kicad-cli-extended (Hybirdss)
- After an autoroute added 9 DRC errors, fab package still produced a JLC Gerber zip marked complete true with exit 0, unless the caller remembered a --fail-on-drc flag. The author's own words: an agent that gates on complete would send a shorted board to the fab.ECAD · impact 74
- On KiCad's pic_programmer demo, pcb place near put a VCC pad on another net's track and exited 0, so DRC later found shorts and solder mask bridges. The update step also reported unrouted connections using pre-placement coordinates about 100 mm off, and a worker crash reported placed.skipped with exit 0.ECAD · impact 74
- An agent branches on the tool's exit code and stdout, and several paths sent it the wrong way: a rolled-back save printed a success-shaped result, two processes editing one project failed as an internal error, and a refusal before any save said commit_state unknown, which the skill tells the agent means repair storage.ECAD · impact 66
- An autoroute threw away 651 seconds of routing. Grid auto refinement failed on its last step after 651 s on pic_programmer, exit 2, nothing saved. The DRC before/after gate also counted unrouted connections as new errors, so a partial route was refused and nothing saved. Follow-up to PR #10 from the 7:41 sweep.ECAD · impact 66
- On a non-English machine every ERC fix hint came back null because the wrapper parsed kicad-cli's translated messages. On KiCad 10.0.8 a valid STEP export got reported as a crash because the check looked for an English log line that build no longer prints.ECAD · impact 66
- The autoroute and placement gates compare KiCad DRC before and after an edit by item UUID. KiCad 5 boards store no UUIDs for pads or some tracks, so every load invents new ones and every old finding looked new. A routing edit far from the problem exited with DRC has 1 new error(s) and a placement was refused. Two earlier fixes matched findings by position, then by position and description, and reviewers broke both.ECAD · impact 66
