kaiwu-qubo

kaiwu-qubo is a skill for Claude Code, Codex from xi-zhao/OpenQuantum. It costs 45 tokens per session (823 once invoked), scanned A, original, MIT.

A local Kaiwu tool for constructing QUBO models with optional squared penalties for linear equality constraints, then converting them to Kaiwu's Ising representation. A penalty makes violating a constraint add energy to a candidate solution.

In plain words
What is it for?
Use it to build and inspect binary optimization models, evaluate chosen assignments, and prepare coefficients for a later solver such as Ocean. It does not search for an optimum or guarantee that a finite penalty produces a feasible best solution.
Why use it?
It makes the objective, constraint residuals, penalty energy, and total energy explicit without requiring a solver or hardware. This helps catch coefficient and sign-convention mistakes before passing the model to another optimizer.

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

kaiwu-qubo 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

Kaiwu Community 符号 QUBO 建模

原生 SDK 路径

本能力同时支持 Kaiwu Community 的原生公开 API。用户需要 上游社区版表达式、约束、QUBO/Ising 转换与优化接口 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 kaiwu-qubo 定位环境,按完整 SDK 工作流执行。模块导航:kaiwu;导航不是 API 白名单。

固定的是 Kaiwu Community;商业服务和企业版不是该发行版的一部分。

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。

Agent 经 Harness 调用 kaiwu_local 提供的 build_kaiwu_qubo。本 Skill 负责模型选择和结果解释,Tool 在独立 Python 环境执行真实上游 SDK。

输入目标函数的 linear、quadratic=[{i,j,bias}]、offset,以及可选 constraints=[{coefficients,rhs,penalty}]。每个约束贡献 penalty*(coefficients.x-rhs)^2;penalty 必须为正,变量及约束维度必须一致。

SDK 使用真实 Binary 表达式与 QuboModel。输出 variableNames 按输入索引排列,包括零系数变量。QUBO 能量为 x^T quboMatrix x + quboOffset;非对角元严格按矩阵相乘计数,不另乘二。

Kaiwu 的 Ising 符号约定是 E=-s^T isingMatrix s + isingOffset。设置 s_i=2*x_i-1,并把额外的最后一个辅助 spin 固定为 +1。不要直接把这一矩阵当成通常正号的 J 系数表。

assignments 是要评估的二进制向量,可为空。返回原目标能量、每个等式残差、罚项能量和总能量。此动作只建模和评估,不求解;有限罚项不保证最优解可行。后续可将编译的 QUBO 转为 Ocean 等求解器的对应系数时保留 offset 与非对角元约定。

只安装 Apache-2.0 的 kaiwu-community,不使用企业版 kaiwu、license、数据上报或真机优化器。

计算规模由调用方选择,后端数值表示限制仍适用。资源限制用 execution 设置,与模型参数分开。先运行 node scripts/setup-paper-tools.mjs kaiwu-qubo 显式准备固定依赖;计算调用不安装依赖或联网,数值库可能写本地缓存。

固定上游版本:1.0.7;来源与许可见上游仓库(Apache-2.0)。本地数值和协议检查属于开发证据;当前 L1,scientificValidation=not_evaluated,成功执行不等于最终科学 Acceptance。

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

kaiwu-qubo is a skill published in the GitHub repository xi-zhao/OpenQuantum (75 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 823 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 2026-09-28.
