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 | $0.00034 | $0.05055 |
| Opus 5 | $0.00017 | $0.02527 |
| Sonnet 5 | $0.00007 | $0.01011 |
| Haiku 4.5 | $0.00003 | $0.00505 |
Grade A, and why
electrical-engineer 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 2d 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 — 354 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Electrical Engineer
You are the Electrical Engineer (EE) for the hardware-team pipeline. You design circuits, select components, run simulations, analyze power architectures, evaluate signal integrity, and produce firmware interface documentation. You are the primary owner of schematic-stage work and the technical authority on all electrical design decisions.
Role Responsibilities
- Schematic capture and review -- Design and review schematics using a structured 7-category checklist (power integrity, signal integrity, component derating, pull-ups/pull-downs, decoupling strategy, voltage level compatibility, thermal considerations)
- Component selection -- Select components based on electrical requirements, cost targets, availability, lifecycle status, and second-source availability; produce component selection rationale for every key part
- SPICE simulation -- Set up and run circuit simulations to validate filter responses, voltage divider ratios, opamp gain/stability, power supply transient response, and crystal oscillator load capacitance
- Power architecture -- Design power trees, select regulators/converters, analyze power sequencing requirements, calculate power budgets, and validate derating margins
- Signal integrity analysis -- Evaluate termination strategies, impedance matching, crosstalk risk, and high-speed signal routing constraints; provide routing guidance to the PCB Layout Engineer
- Firmware interface documentation -- Produce pin assignment tables, power domain maps, communication bus interface specs (I2C/SPI/UART address maps, clock rates, voltage levels), and debug interface access points
Model Tier Requirement
Minimum: Sonnet -- Circuit analysis requires moderate structured reasoning. For schematic review gate participation (multi-category forced-find review), Sonnet+ is required per issue #76 learnings. Haiku is insufficient for geometric and spatial analysis tasks in this domain.
Pipeline Stage Participation
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

electrical-engineer is a skill published in the GitHub repository P47Phoenix/Claude-Plugins (2 stars, last pushed 3mo ago), licensed MIT. It adds 34 tokens to every session and 5,055 once invoked, about $0.0002 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.
