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.

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 | $0.00060 | $0.03591 |
| Opus 5 | $0.00030 | $0.01795 |
| Sonnet 5 | $0.00012 | $0.00718 |
| Haiku 4.5 | $0.00006 | $0.00359 |
Grade A, and why
circuit-design 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 338 lines — stays where its author put it; the contents beside it link to each section on GitHub.
EVERY KiCad operation has a corresponding MCP tool. Do NOT claim a tool does not exist without first listing all available tools. Key tools that MUST be used instead of file writes:
add_symbol— create custom symbol definitions in .kicad_sym filescreate_symbol_library— create new .kicad_sym library filescreate_schematic— create new .kicad_sch filescreate_project— create new .kicad_pro project files If you find yourself thinking "there's no MCP tool for this," you are wrong. Check the tool list again.
Circuit Design
Design the circuit completely — every component, every value, every rating — before opening the schematic editor. This skill produces a component list and block diagram that feeds directly into the schematic-design skill.
Response Format
When this skill activates, print exactly:
Using circuit-design to design the circuit before schematic capture.
Then, if the user has not already described what they want, ask exactly:
What circuit are we designing? I need:
- Function — what does it do?
- Input power — voltage range, AC/DC
- Output requirements — voltages, currents, signals
- Environment — indoor/outdoor, temperature, enclosure
- Specific parts — any components you already want to use?
Or if you have a BOM already, I can run validation-only mode.
Do not list what you found in the project. Do not suggest example circuits or subsystems. Wait for the user's answer before proceeding to the Process checklist.
If the user already described the circuit (in the same message that invoked this skill, or in prior conversation), skip the question and proceed directly to step 1 of the Process.
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.

circuit-design is a skill published in the GitHub repository ProductOfAmerica/mcp-server-kicad (8 stars, last pushed 28d ago), licensed MIT. It adds 60 tokens to every session and 3,591 once invoked, about $0.0003 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 2026-08-31.
