Spice

Quality score: 70/100 · Category: General · Sub-category: automation

Run automatic SPICE simulations on subcircuits detected from KiCad schematic analysis — validates filter frequencies, divider ratios, opamp gains, LC resonance, and crystal load capacitance. Supports ngspice, LTspice, and Xyce (auto-detected). Generates testbenches, runs batch mode, produces structured pass/warn/fail report. Use when the user asks to simulate, verify, or validate any analog subcircuit — RC filters, LC filters, voltage dividers, opamp circuits, crystal oscillators. Also for "simulate my circuit", "run spice", "verify with simulation", "check my filter cutoff", "does this divider give the right voltage", "what's the bandwidth of this opamp stage". Consider suggesting simulation during design reviews when the schematic analyzer reports simulatable subcircuits and a SPICE simulator is available.

What this skill does

Spice is a production-ready Claude Code skill (quality score 70/100) in the automation sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/spice/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user asks to simulate, verify, or validate any analog subcircuit — RC filters, LC filters, voltage dividers, opamp circuits, crystal oscillators. Also for "simulate my circuit", "run spice", "verify with simulation", "check my filter cutoff", "does this divider give the right voltage", "what's the bandwidth of this opamp stage".

Who uses this skill

The Spice skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It is part of the open ClaudSkills registry, a community-curated catalog of 15,000+ capabilities you can install for Claude Code — the Claude CLI agent.

How to install

Free

Manual install (2 steps)

mkdir -p ~/.claude/skills/spice
curl -L https://claudskills.com/skills/spice/SKILL.md \
  -o ~/.claude/skills/spice/SKILL.md

Or just download SKILL.md directly and drop it into ~/.claude/skills/spice/. Claude Code auto-discovers it on next session.
