Use when writing or editing ngspice circuit netlists (.cir, .sp, .spice), working with ngspice scripting (.control blocks), or interpreting simulation results. Covers ngspice-specific SPICE syntax, behavioral sources, .control scripting, Monte Carlo via control loops, parameters, XSPICE, .save, .MEAS, convergence, and common gotchas that cause silent errors. Use this skill whenever the user mentions ngspice, or is writing SPICE netlists targeting ngspice rather than LTspice.
