monoprop-propagation

monoprop-propagation is a skill for Claude Code, Codex from xi-zhao/OpenQuantum. It costs 49 tokens per session (541 once invoked), scanned A, original, MIT.

A scientific-computing workflow using monoprop's public API for Pauli and Majorana operators, gate generators, and propagation. It supports custom programs with gradients and controlled truncation of the calculation.

In plain words
What is it for?
Use it to construct operator models, generate gates, propagate states or operators, compute gradients, and test whether a truncated result has converged.
Why use it?
It makes the sign conventions, operator order, angles, and truncation choices explicit, which helps avoid ambiguous quantum calculations. Small systems can be checked against exact matrices, but the run itself does not establish scientific correctness.

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

monoprop-propagation 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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (references/native-example.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.

monoprop-propagation is a skill published in the GitHub repository xi-zhao/OpenQuantum (75 stars, last pushed yesterday), licensed MIT. It adds 49 tokens to every session and 541 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-14.
