Kstack

Create a KiCad schematic with components placed and nets labelled, starting from a high-level spec (MCU + peripherals list). Resolves symbols from the user's configured library paths (see `kstack_config`) — typically a personal symbol folder, KiCad 9 stock libraries, or a downloaded-parts staging area. Consults a knowledge graph of past designs for pin conventions and footprint history. Generates a ready-to-open KiCad 9.0 project. Invoke for: "create a schematic for STM32 + RS485", "generate a KiCad project with ESP32 and optocoupler", "new board for this MCU and these parts", "assemble a schematic with these components".

Build a functional peripheral knowledge graph from KiCad projects. Parses full net connectivity (hierarchical sheets included), classifies components by role (MCU, RS485, sensor, LDO, etc.), then aggregates across projects to find which peripheral blocks appear in ≥2 projects and which MCU pins they consume. Invoke for: "build a block library from my projects", "extract reusable blocks", "catalog my designs", "what peripherals do I reuse", "which pins does RS485 need on the ESP32".

Register downloaded KiCad symbols and footprints into KiCad's library tables (sym-lib-table, fp-lib-table) so they become available in eeschema / pcbnew without manually using Preferences > Manage Libraries. Handles vendor-style folders such as: ~/Documents/footprints/ BSS138/ (*.kicad_sym, *.kicad_mod) ULN2803AFW/ (*.kicad_sym, *.kicad_mod) MyLib.pretty/ (footprint library folder) Invoke for: "add this symbol to KiCad", "register these footprints", "import downloaded library", "make this library available", "set up libraries for this project".

KiCad schematic analysis and connectivity assistant. Parses .kicad_sch files, resolves full net connectivity, and answers questions about components, pins, signal routing, and power rails. Can also apply simple schematic changes (add/remove net labels, add wires). Invoke for: "what connects to X pin Y", "which net is R1 pin 1 on", "trace signal from IN1 to ESP32", "show GND connections", "connect X to Y", "what components are on the 3V3 net", schematic design review questions. Proactively invoke when the user is in a KiCad project directory (contains .kicad_sch) and asks about component connections, nets, or signal paths.
