guppy-programs

guppy-programs is a skill for Claude Code, Codex from xi-zhao/OpenQuantum. It costs 48 tokens per session (912 once invoked), scanned A, original, MIT.

A compiler and simulator for structured quantum programs with measurements, qubit reset, and gates chosen by earlier measurement results. It uses Guppy and Selene to model these dynamic circuits locally.

In plain words
What is it for?
Use it to test mid-circuit measurement, resetting, conditional gates, measurement records, and final qubit states.
Why use it?
It helps check feedback logic and bit ordering without running on quantum hardware or a cloud service. Finite sampling still causes normal statistical variation, while hardware noise and timing are not modelled.

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

guppy-programs 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 4d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (mcp/bridge.py, mcp/contracts.mjs, mcp/server.mjs, …), 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 it actually says

Guppy 与 Selene 混合程序

原生 SDK 路径

本能力同时支持 Guppy / Selene 的原生公开 API。用户需要 任意 Guppy 程序、控制流、编译、模拟与结果处理 时,由 Agent 在固定依赖环境中编写和运行任务代码,不限于下文便捷 Tool 的预设模型。

使用 node scripts/sdk-access.mjs inspect guppy-programs 定位环境,按完整 SDK 工作流执行。模块导航:guppylang、selene_sim;导航不是 API 白名单。

下文关于模型、门集、输入与预算的限制描述便捷 Tool 的合同;原生 SDK 另受上游版本、可选依赖、宿主资源与用户授权约束。已禁用或被拒绝的动作不能借代码路径绕过。执行状态和科研验收分别报告。

调用 guppy_local 的 simulate_guppy_feedback。固定 guppylang==1.1.1 与 selene-sim==0.3.2, 均为 Apache-2.0。先显式执行 node scripts/setup-paper-tools.mjs guppy-programs;需要 Python 3.12, 锁中包含平台对应的原生编译与仿真组件。

  1. 指定 numQubits、结构化 operations、shots 和 seed。初态为全零;支持 H/X/Y/Z/S/T、CX、 RX/RY/RZ,以及 MEASURE_RESET。旋转 angleRadians 用弧度,适配转换为 Guppy 的半周单位。
  2. MEASURE_RESET 在 Z 基测量、消耗当前 qubit,再分配全零 qubit;测量按出现顺序编号。 后续门通过 conditionMeasurement 和 conditionValue 控制是否执行。默认 -1 表示无条件。 测量自身必须无条件,保证所有运行分支拥有相同的测量记录结构。
  3. 例如 H(q0) → 测量复位(q0) → 若结果为 1 则 X(q1),应该得到测量值与 q1 完全相关、q0 恒零。 从 counts 同时检查 measurementBits 和 finalBits,不要只看最终直方图。
  4. measurementBits 按测量出现顺序排列,finalBits 按 q0、q1、… 排列;没有中途测量时前者为空串。 programSource 是工具从固定语法生成的可读程序,HUGR 大小与 SHA-256 来自真实 Guppy 编译结果。

输入不接受 Python、QIR、模块路径或任意代码。越界/重复目标、错误门元数、未来测量索引会显式失败。 SDK 环境或本地编译失败时保留错误,不以其他模拟器替换。execution 控制资源,规模由调用者选择。 临时本地编译产物在调用后清理,Zig 缓存保留于工作区。

Selene 使用 QuEST 理想态矢量后端;有限 shots 有统计波动。这里没有噪声、设备时序、反馈延迟或云运行。 编译与分支行为核对属于 L1 工程证据,scientificValidation=not_evaluated,不构成最终科学 Acceptance。

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.

guppy-programs is a skill published in the GitHub repository xi-zhao/OpenQuantum (75 stars, last pushed yesterday), licensed MIT. It adds 48 tokens to every session and 912 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 2026-09-29.
