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 | $0.02585 | $0.02585 |
| Opus 5 | $0.01293 | $0.01293 |
| Sonnet 5 | $0.00517 | $0.00517 |
| Haiku 4.5 | $0.00259 | $0.00259 |
Grade C, and why
universal-netlist CLAUDE.md scanned grade C with 2 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 today.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Universal Netlist MCP Server
Overview
MCP server for querying EDA netlists and tracing circuit connectivity. Supports Cadence OrCAD/CIS (.DSN), Altium Designer, KiCad, and Universal Netlist formats.
DAT parsing and export_cadence_netlist are dormant in MCP, controlled by
src/features.ts. Keep their implementations and regression tests. The CLI
coverage command and developer golden-generation scripts still use DAT as
an independent reference; do not advertise that path to MCP clients.
Development
Setup
bun install # Prefer bun over npm
npm run setup # Initialize test fixture submodules
npm run dev
Note: Test fixtures are git submodules. Run npm run setup after clone.
Dependencies
Both lockfiles are committed. Binary packaging installs from bun.lock; CI installs
from package-lock.json and produces the npm tarball that is later published unchanged.
When you change a dependency,
regenerate both lockfiles in the same commit:
bun install # updates bun.lock
npm install --package-lock-only # updates package-lock.json
CI installs with npm ci and binary packaging with bun install --frozen-lockfile.
Both fail if the lockfile does not match package.json, so an out-of-date lockfile is
caught instead of being silently re-resolved.
Commands
npm run dev # Run with tsx (auto-reload)
npm run build # Compile TypeScript to dist/
npm run start # Run compiled version
npm run type-check # TypeScript type checking
npm run lint # ESLint
npm run lint:fix # ESLint with auto-fix
npm test # Run tests with Vitest
npm run test:watch # Run tests in watch mode
npm run compile:all # Build the five per-arch binaries (any host)
npm run compile:darwin-universal # Add the lipo'd macOS universal binary (macOS only)
Binary Compilation
Bun compiles the TypeScript into standalone executables. One script does this, and
release.yml and the compile:* npm scripts all call it, so you can reproduce a
release binary locally:
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.

universal-netlist CLAUDE.md is an instructions file published in the GitHub repository IntelligentElectron/universal-netlist (34 stars, last pushed yesterday), licensed Apache-2.0. It adds 2,585 tokens to every session, about $0.0129 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
