Close the loop names no source for an off-the-shelf part's mass and center of mass, so a torso that is 2.4 kg vendor parts in 4.6 kg total has no honest COM.
Recurring agent failure issue in armature (rioharper)
What engineers report
A recurring agent failure problem in armature (rioharper) that mostly hits the mechanical designer.
Failure pattern: validation / 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

More recurring errors in armature (rioharper)
- The armature-cad skill tells the agent to confirm 'the fabrication reality', meaning in-house machining envelope, printer, sheet stock, bend capability and minimum drill sizes, but it names a file only for an outside shop's questionnaire. The in-house limits and a shop's published limits have no home, so each project invents one.MCAD · impact 74
- The SOLIDWORKS equations file mirrors the project ledger, but nothing fails when it falls behind, so a changed entry can merge with the old value still in the file.MCAD · impact 74
- An agent skill set routes findings that move a requirement, part or BOM number back to the spec, but the spec skill only knows how to write a first spec. On one project "two revisions, each improvised." One wrote its account in a closing comment, the other in a side report that maps each routed item to spec text and lists deferred ledger edits.MCAD · impact 66
- Running the spec plugin end to end on a test project turned up a list of gaps, each with the workaround used now. The drive envelope says 'winding hot' but reads the winding at starting temperature when the motor has no thermal model. A source's overvoltage trip stops both sourcing and sinking, while a real BMS opens only its charge path. The motor has no peak torque field, so stall is computed as Kt times peak current, past the printed peak.Verification · impact 66
