kicad-happy is a collection of coding-agent skills and tools that inspect KiCad schematics, PCB layouts, and Gerber files for electronics design issues. It is for hardware designers who want automated reviews, simulations, datasheet checks, component sourcing, and fabrication preparation. The catalogue entries are its agent skills, rules, plugin, and instruction for integrating this workflow with coding agents.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00119 | $0.02230 |
| Opus 5 | $0.00060 | $0.01115 |
| Sonnet 5 | $0.00024 | $0.00446 |
| Haiku 4.5 | $0.00012 | $0.00223 |
Grade A, and why
pcbway scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

PCBWay — PCB Fabrication & Assembly
PCBWay is a PCB fabrication and assembly service based in Shenzhen, China. It is an alternative to JLCPCB with similar capabilities and pricing.
Typical usage: Order bare prototype PCBs + framed stencil from PCBWay during prototyping (parts sourced separately from DigiKey/Mouser, hand-assembled in lab). For production runs (100s qty), order fully assembled boards from PCBWay using turnkey component sourcing (PCBWay sources parts by MPN). JLCPCB is the primary alternative. For BOM management, gerber/CPL export, and stencil ordering, see the bom skill.

Key Differences from JLCPCB
| Feature | PCBWay | JLCPCB |
|---|---|---|
| Component sourcing | Turnkey (PCBWay sources by MPN) | LCSC parts library (you provide LCSC PNs) |
| Parts library | No fixed library — sources globally | LCSC library (basic/extended parts) |
| Assembly fee model | Quote-based per project | Per-part fees (basic free, extended $3 each) |
| Pricing turnaround | Manual quote, 1–2 business days | Instant online pricing |
| BOM format | MPN-based (manufacturer part numbers) | LCSC PN-based |
Plan around manual quoting. PCBWay assembly requires a human-reviewed quote before you can place the order — typically 1-2 business days after uploading files. JLCPCB shows assembly pricing instantly at checkout. If you're prototyping and need to iterate quickly, the JLCPCB feedback loop is much tighter. PCBWay's value is in sourcing parts JLCPCB can't, not in turnaround speed.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pcbway is a skill published in the GitHub repository aklofas/kicad-happy (1,175 stars, last pushed 9d ago), licensed MIT. It adds 119 tokens to every session and 2,230 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
altium-library
Create and verify Altium schematic symbols (.SchLib) and PCB footprints (.PcbLib) from datasheets and 2D drawings, as code. Use whenever a part library must be made, fixed, measured from a drawing, or checked. Triggers: "make a footprint", "create a symbol", "add this part to the library", "SchLib", "PcbLib"…
circuit-design
Use when designing an electronic circuit from requirements, choosing topology or regulator type, selecting component values, planning protection circuits, or deciding what goes on a board before schematic capture begins. Also use when the user asks "what components do I need" or "how should I power this.".
using-kicad
Use when starting any conversation involving electronics, KiCad, PCB design, schematic capture, circuit design, or EDA tasks.
schematic-plan
Use after circuit-design produces a validated BOM (specs/bom.md) to plan exact component placement coordinates and wiring before schematic capture begins. Pure planning — no file modifications.
altium-pcb-placement
Altium PCB component placement — derive board size, decide rotation for main ICs and connectors, split zones, generate a 1:1 placement plan drawing, then inject real coordinates after approval, and check overlaps. Triggers: "PCB placement", "place the components", "how big should the board be", "board outline", "start…
altium-schematic-review
Review an Altium schematic (.SchDoc) — find unconnected pins, missing footprint links and net errors, then judge each candidate against the datasheet before calling it a defect. Triggers: "review this schematic", "check my circuit", "ERC", "floating pins", "unconnected", "any missing footprints", "does this schematic…
