analog-design-em

analog-design-em is a plugin for Claude Code from hdl-tools/analog-chip-design-agents. Its manifest loads nothing; the 1 skill, 1 agent it bundles cost 250 tokens per session together, scanned A, original, MIT.

A chip-design add-on for simulating electromagnetic behaviour in passives and antennas, then creating frequency-response and circuit-equivalent models.

In plain words
What is it for?
Use it to solve structures such as inductors, transformers, transmission lines, baluns, and antennas, extract S-parameters, and fit lumped models.
Why use it?
It connects physical RF structures to circuit-level simulation, where their real frequency-dependent behaviour matters.

Plugin for Claude Code

Written for Claude Code: a Claude Code plugin manifest.

Good fit Use it to solve structures such as inductors, transformers, transmission lines, baluns, and antennas, extract S-parameters, and fit lumped models.

Security

Grade A, and why

analog-design-em 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 1mo 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.

What it installs

The manifest is a name and a version. 1 skill, 1 agent travel with it, and installing the plugin installs all of them — 250 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.

analog-design-em is a plugin published in the GitHub repository hdl-tools/analog-chip-design-agents (22 stars, last pushed 4mo ago), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. 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.
