symmer-tapering SKILL.md skillA
symmer-tapering 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/symmer-tapering@git:20261012.5ce3b3ePins git:20261012.5ce3b3e in mdr.lock. Pin the fingerprint instead.

用固定 Symmer 将实 Pauli Hamiltonian 投影到显式指定的对称性扇区，降比特，可选同一扇区的独立完整能谱比较。.
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
# Symmer 对称性降比特
<!-- BEGIN NATIVE SDK ACCESS -->
## 原生 SDK 路径
本能力同时支持 **Symmer 的原生公开 API**。用户需要 PauliwordOp、投影、对称性、tapering 与子空间方法 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 symmer-tapering` 定位环境，按[完整 SDK 工作流](../quantum-sdk-workbench/references/workflow.md)执行。模块导航：`symmer`；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 -->
用户已有 Hamiltonian 和要研究的对称性扇区时，调用 Harness 注册的 `symmer_local.taper_symmer_hamiltonian`。本能力使用 Symmer 的 S3Projection 稳定子投影原语；不自动选择基态扇区。
- `terms` 用 `{pauli, coefficient}` 表示 实 Pauli Hamiltonian；量子位数和项数由输入决定。字符串从左到右为 q0、q1……；重复项先合并。
- `symmetries` 用 `{pauli, sector}` 指定正号 Pauli 算符及其 ±1 本征值。至少一个生成元，允许全部量子位投影为标量（reducedQubits=0，Pauli 字符串为空）；生成元必须两两对易、GF(2) 独立，并与每个非零 Hamiltonian 项对易。
- 如果用户未指定扇区，先说明对称性选择并取得具体输入，不能将 Tool 的示例默认扇区当成用户模型的全局基态扇区。必要时分别运行多个允许扇区比较最低能量。
- 返回 reducedTerms 和 sectorDimension，可选 reducedSpectrum 和 referenceSectorSpectrum。独立参考取投影算符 range 内的正交基，在该子空间对 Hamiltonian 对角化；不能把全维 PHP 的零本征值混入扇区能谱。
- 降维 Pauli 轴是 Symmer 变换后的坐标，不能直接视作删去某些物理量子位。保谱仅限指定扇区，最低值不自动等于全系统基态。

How to install
mdr add xi-zhao/openquantum/symmer-tapering@sha256:d48ae015a58a5587The 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.
