ee SKILL.md skillA
ee from mattpainter701/kicad_automations is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add mattpainter701/kicad_automations/ee@git:20260710.9da1c93Pins git:20260710.9da1c93 in mdr.lock. Pin the fingerprint instead.

Electrical and electronic engineering reference — circuit analysis, component selection, power supply design, signal integrity, RF, thermal, EMC, and test & measurement. Use for design questions, calculations, component vetting, and first-principles analysis. Do not orchestrate a complete new board from requirements; use circuit-weaver for that end-to-end workflow.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Core Circuit Laws ### DC Analysis ``` V = IR Ohm's Law P = VI = I²R = V²/R Power KVL: ΣV around loop = 0 Kirchhoff's Voltage Law KCL: ΣI into node = 0 Kirchhoff's Current Law ``` ### Voltage Divider ``` Vout = Vin × R2 / (R1 + R2) Rload effect: Vout_actual = Vin × (R2||Rload) / (R1 + R2||Rload) For < 1% load error: Rload > 100 × R2 ``` ### Thevenin / Norton ``` Vth = open-circuit voltage at terminals Rth = resistance seen from terminals with all sources zeroed (V→short, I→open) In = Vth / Rth ``` ### Superposition For linear circuits: activate one source at a time, zero others, sum results. --- ## Passive Components ### Resistors | Parameter | Calculation | Notes | |-|-|-| | Power derate | P_rated × 0.5 at 70°C | Derate linearly to 0 at T_max | | Noise (Johnson) | Vn = √(4kTRB) | k=1.38e-23, B=bandwidth | | Tolerance effect | ΔVout/Vout = √(ΔR1²+ΔR2²) / (R1+R2) | Worst-case RSS | **Standard E-series values:** E12 (10% tol), E24 (5%), E48 (2%), E96 (1%), E192 (0.5%) **SMD sizes:** 0201, 0402 (¼W), 0603 (⅒W), 0805 (⅛W), 1206 (¼W), 2512 (1W) ### Capacitors | Type | Voltage coeff | Temp coeff | Use case | |-|-|-|-| …

How to install
mdr add mattpainter701/kicad_automations/ee@sha256:8913d525febe031dThe line at the top of this page pins the label git:20260710.9da1c93, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
