| description | Circuit, power budget, protection, and thermal risk checks for robot-dog and
hardware virtual prototypes. Use this skill whenever the user asks whether a
circuit is reasonable, power rails have enough margin, motor current is safe,
protection is adequate, or PCB/electronics thermal risk blocks a physical prototype.

circuit-simulation
This skill checks early electrical reasonableness for robot-dog virtual prototypes.
It consumes a circuit metadata contract, then writes deterministic circuit, power,
thermal, and protection reports.
When To Use
Use this skill for:
- Battery, fuse, emergency-stop, reverse-polarity, TVS, and undervoltage checks.
- Power rail current and power margin checks.
- Motor driver peak/continuous current checks.
- Thermal risk estimates for regulators, motor drivers, and MOSFETs.
- Producing
circuit_check.json, power_budget.json, and thermal_report.json
for robot-dog-digital-twin gates.
Workflow
- Read
<project>/circuit_requirements.yaml.
- Check ERC/DRC status when provided.
- Check battery voltage/current limits and total power budget.
- Check each power rail for current margin and regulator thermal risk.
- Check motor driver current margin.
- Check protection coverage.
- Write reports into
<project>/reports/.
Commands

Rules
- Keep MVP checks deterministic and conservative.
- Treat any failed ERC/DRC, missing emergency stop, missing fuse, or current margin below 20% as a blocker.
- Treat estimated component temperature above its declared limit as a blocker.
- Do not place orders, energize hardware, or claim physical safety from this report alone.
- Do not import sibling subskill code. Read files only.
