Create, import, analyze, or resume an end-to-end Circuit Weaver electronic design with durable project state. Load the canonical workflow from skills/circuit-weaver/SKILL.md. Use kicad for one-off file inspection, bom for sourcing, and design-wizard only when explicitly requested.

Use only for an explicitly requested step-by-step Circuit Weaver questionnaire. Load the canonical workflow from skills/design-wizard/SKILL.md; use circuit-weaver for ordinary automatic new-design requests.

Route non-critical nets on a real KiCad PCB or Specctra DSN through Circuit Weaver's fail-closed Freerouting integration. Use after placement and net-class setup when the user requests autorouting, a validated SES session, routing diagnostics, or post-route cleanup. Keep critical power, RF, clock, crystal, switching, and differential nets manual.

Generate KiCad schematics from a Circuit Weaver design.yaml or a project's own checked-in generator. Use for large, repetitive, or machine-synchronized designs. Prefer the Circuit Weaver CLI unless the project actually contains and documents its own generation scripts.

Design and verify professional multi-sheet KiCad hierarchies generated from Circuit Weaver functional sections. Use when adding, splitting, renaming, or reviewing schematic sheets, cross-sheet interfaces, root symbols, sheet ownership, or final hierarchy ERC.

Review Circuit Weaver's exhaustive placement proposal and apply approved SVG coordinates to a real electrically annotated KiCad PCB. Use after schematic generation for placement optimization, official-reference review, interactive SVG editing, strict reference reconciliation, and PCB placement handoff. Do not treat review artifacts as fabrication data.

Pin-to-net mapping auditor -- verifies that every IC pin in the schematic is connected to the correct net, matched against a pin map source of truth (CSV, datasheet table, or Python dict). Critical for BGA/QFN devices where swap errors are invisible to DRC/ERC.

Cross-reference design audit -- validates consistency across spec, schematics, BOM, pin maps, and PCB layout. Catches disagreements before fabrication. Run after any significant design change.

Guidance for editing Claude Code agents. Use when Claude touches agent markdown files so tool scopes, MCP wiring, memory scope, isolation, and agent hooks are configured safely.

Guidance for editing Claude Code hooks. Use when Claude touches hook scripts, hook JSON, or settings files that register hooks so matcher selection, shell choice, timeouts, and blocking behavior stay correct.

Automatic memory extraction skill — triggered by file operations to extract durable learnings from session context. Runs in the background via the memory-extractor agent.

Guidance for editing Claude Code skills. Use when Claude touches skill folders or SKILL.md files so slash-command naming, frontmatter, helper scripts, and conditional paths stay coherent.

BOM (Bill of Materials) management for electronics projects — the primary orchestrator skill that coordinates DigiKey, Mouser, LCSC, element14, JLCPCB, PCBWay, and KiCad skills into a unified workflow. Create, update, and maintain BOMs with part numbers, costs, quantities stored as KiCad symbol properties. ALWAYS trigger this skill for any task involving component sourcing, pricing, ordering, distributor searches, BOM export, or fabrication preparation — even if the user names a specific distributor or fab house (e.g. "search DigiKey for...", "generate JLCPCB BOM", "order from Mouser"). This skill decides which distributor/fab skills to invoke and in what order. Also trigger on phrases like "what parts do I need", "order components", "how much will this cost", "export for JLCPCB", "find parts for this board", "cost estimate", "compare pricing", or "check stock".

Search DigiKey for electronic components and download datasheets — primary source for prototype orders and the preferred API-based method for fetching datasheets. Find parts by keyword or part number, check pricing/stock, download datasheets directly via API, analyze specifications. Sync and maintain a local datasheets directory for a KiCad project — extract components from schematics, download all missing datasheets, keep them up to date. Use with KiCad for BOM creation and part selection. Use this skill when the user asks about electronic components, part specifications, datasheets, footprints, pricing, stock availability, or needs to download/read a datasheet — even if they don't mention "DigiKey" by name. Also use when the user says "sync datasheets", "download datasheets for my board/project", or mentions a datasheets directory. DigiKey is the default distributor for prototyping and the preferred datasheet source because its API returns direct PDF links without web scraping. For package cross-reference t

Search Newark, Farnell, and element14 for electronic components — find parts by MPN or distributor part number, check pricing/stock, download datasheets, analyze specifications. One unified API covers all three storefronts (Newark for US, Farnell for UK/EU, element14 for APAC). Free API key, simple query-parameter auth, no OAuth. Datasheets download directly from farnell.com CDN with no bot protection. Sync and maintain a local datasheets directory for a KiCad project. Use this skill when the user mentions Newark, Farnell, element14, needs parts from a non-US distributor, wants to compare pricing across regions, or needs datasheets from a source that doesn't require complex API auth. For package cross-reference tables and BOM workflow, see the `bom` skill.

JLCPCB PCB fabrication and assembly — BOM/CPL generation, basic vs extended parts, assembly constraints, design rules, ordering workflow. Use with KiCad for JLCPCB manufacturing. Use this skill when the user mentions JLCPCB, wants to order PCBs or assembled boards, needs prototype bare PCBs and stencils, wants to know JLCPCB design rules and capabilities, or is asking about PCB manufacturing costs or turnaround times. For gerber/CPL export, stencil ordering, and BOM management, see the `bom` skill.
