Use when refactoring, cleaning up, or enhancing the lib-electronic-components codebase. Provides guidance on architecture patterns, known issues, duplication hotspots, and recommended improvements.
Base skill for working with electronic components in this library. Use when adding new component types, manufacturer handlers, or working with MPN (Manufacturer Part Number) operations, BOM entries, or component classification.
Use this skill BEFORE creating a PR to ensure all documentation, skills, and learnings are updated. Critical for preserving institutional knowledge and preventing documentation drift.
Use when working with component similarity calculations - comparing MPNs, finding equivalent parts, implementing new similarity calculators, or understanding how component matching works.
Use when working with capacitor similarity calculations - comparing ceramic/electrolytic/film capacitor MPNs, understanding value/voltage/dielectric matching, or capacitor-specific similarity logic.
Use when working with connector similarity calculations - comparing connector MPNs, understanding pin count/pitch/family matching, or connector-specific similarity logic.

Cosmo Electronics is a Taiwanese manufacturer specializing in optocouplers and photo interrupters. Their product lines use the "KP" prefix family.
Cosmo MPNs follow these general patterns:
KP[SERIES][VARIANT][-SUFFIX]
| | |
| | +-- Optional: -1=DIP-4, C/S=SMD
| +-- Variant letter (optional)
+-- 4-digit series (e.g., 1010, 2010, 4010)
KPC[SERIES][CTR-GRADE][PKG-IND][-SUFFIX]
| | | |
| | | +-- Optional suffix
| | +-- Package indicator (S/G=SMD, T=SOP)
| +-- CTR Grade: A/B/C/D
+-- 3-digit series (e.g., 817, 357)
KP1010-1
| | |
| | +-- -1 = DIP-4 package
| +-- 1010 = Single channel phototransistor
+-- KP = Phototransistor optocoupler series
KPC817C-1
| | | |
| | | +-- -1 = DIP-4 package
| | +-- C = CTR grade (200-400%)
| +-- 817 = General purpose high isolation
+-- KPC = High isolation optocoupler
KPH121S
| | |
| | +-- S = SMD package
| +-- 121 = High speed single channel
+-- KPH = High speed optocoupler
