clifft-sampling SKILL.md skillA
clifft-sampling from xi-zhao/openquantum is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add xi-zhao/openquantum/clifft-sampling@git:20261012.5ce3b3ePins git:20261012.5ce3b3e in mdr.lock. Pin the fingerprint instead.

用固定 Clifft 对 Clifford+T 电路做带噪采样或 Stim 格式的纠错记录采样，按活跃宽度控制成本，可选最终测量密度矩阵参考。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Clifft 近 Clifford 采样 <!-- BEGIN NATIVE SDK ACCESS --> ## 原生 SDK 路径 本能力同时支持 **Clifft / Stim 的原生公开 API**。用户需要 自定义电路、噪声模型、测量与采样程序 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 clifft-sampling` 定位环境，按[完整 SDK 工作流](../quantum-sdk-workbench/references/workflow.md)执行。模块导航：`clifft`、`stim`；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。 <!-- END NATIVE SDK ACCESS --> 结构化最终测量调用 Harness 注册的 `clifft_local.sample_clifft_circuit`。用于 T 门干涉、Clifford+T 电路和门后去极化噪声实验。 - 提交结构化 `gates`，仅支持 H、S、T、X、Y、Z、CX、CZ；CX/CZ 的 targets 顺序为控制位、目标位。量子位数、门数和 shots 由输入决定。maxActiveWidth 默认为 null；只有用户显式设置该预算时才按实际 peakActiveWidth 检查。 - 初态固定为全零态；每个门后，在该门涉及的各量子位独立施加 `DEPOLARIZE1(p)`。`p` 是 Pauli 错误总概率，不是直接乘在密度矩阵上的白噪声混合系数。 - 只做最终 Z 测量，位串从左到右为 q0、q1……。密度矩阵参考运行时返回完整位串（complete）；跳过参考时仅返回实际出现的位串（observed_only），频数之和仍等于 shots。 - referenceMode=auto|required|skip；独立密度矩阵参考默认在 6 qubits 内自动运行；required 尝试所请求规模；skip 主动跳过。未运行时 reference.status=not_run，参考概率、TVD、trace error 均为 null。密度矩阵参考描述相同的噪声模型；采样频数仍有有限 shots 不确定度。比较 total variation distance 时结合样本数，不要求频数与解析概率完全相等。 - 该结构化接口不开放中间测量、反馈或 Stim 文本；需要记录采样时使用下述独立 Tool。 …

How to install
mdr add xi-zhao/openquantum/clifft-sampling@sha256:9d0cacee5cd1e999The line at the top of this page pins the label git:20261012.5ce3b3e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
