analog-netlist-crawl

analog-netlist-crawl is a skill for Claude Code, Codex from Arcadia-1/analog-agents. It costs 291 tokens per session (7,902 once invoked), scanned A, original, no licence file.

A tool for examining post-layout parasitic netlists, which are circuit descriptions that include unwanted resistance and coupling introduced by the physical chip layout. It analyzes them without running a SPICE simulation.

In plain words
What is it for?
It helps trace resistance between nodes, find electrically distant device pins, identify badly coupled nets, and locate settling bottlenecks.
Why use it?
It answers detailed connectivity and resistance questions in very large resistor networks when a full simulation is not the immediate need.

Token cost

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.

Security

Grade A, and why

analog-netlist-crawl 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.

The scan reads SKILL.md. This mod also ships 19 executable files (scripts/adapters/__init__.py, scripts/adapters/_util.py, scripts/adapters/mrpp.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 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-netlist-crawl is a skill published in the GitHub repository Arcadia-1/analog-agents (68 stars, last pushed 2mo ago), with no licence file. It adds 291 tokens to every session and 7,902 once invoked, about $0.0015 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.
