Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00052 | $0.00850 |
| Opus 5.5 | $0.00021 | $0.00340 |
| Sonnet 5.5 | $0.00010 | $0.00170 |
| Haiku 4.5 | $0.00005 | $0.00085 |
Grade A, and why
quantum-qfi 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.
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
qfi
本地开源适配。上游指南 ID：algorithms/gradients/qfi。
适用方法
Qiskit QFI/ReverseQGT，纯态量子 Fisher 信息；不将其等同于任意测量的经典 Fisher 信息。
使用步骤
- 先识别用户是在询问原理、要求运行，还是要求生成/修改代码；仅解释时不自动开始计算。
- 阅读共同运行说明和本地实现。可通过已有
quantum_practicesTool 的get动作、id=algorithms/gradients/qfi读取完整理论、原始参数和推导；其中的外部安装命令及 UnitaryLab 后端要求不适用于本地执行。 - 根据任务准备实际输入，核对下面的参数签名。省略输入只会运行教学示例，不能把它冒充用户数据的结果。需要示例以外的 ansatz、oracle、边界条件或输出时，基于开源 SDK 生成可审查的任务代码。
- 使用 Harness 已有的
bash（Windows 为pwsh）Tool 执行。在 OpenQuantum 仓库根目录，先检查示例 Python 环境；缺少依赖时显式执行npm run capability:algorithms:setup -- --group gradients。执行和安装均受现有 Harness 权限、审批、超时及 Job 管理约束。Skill 不启动服务。 - 读取实际结果和错误；保留输入、依赖版本、种子、近似参数与输出。优化未收敛、后选择概率低、码距未计算或样本不足都必须按实际字段报告。通过经典对照或收敛检查支持数值结论；最终科学验收仍为
not_evaluated。
参数：
qfi(angles=None)
最小可运行示例（macOS/Linux；Windows Python 路径见共同说明）：
examples/quantum-algorithms/.venv/bin/python examples/quantum-algorithms/run.py --algorithm qfi
用户参数写入 JSON 文件，追加 --input <path>；需要保留报告时追加 --output <path>。输入规模由用户选择，不能把示例默认值当成算法上限。
来源与边界
上游 MIT 指南：algorithms/gradients/qfi。原文作为参考保存在固定检索库，本文件将执行路线改为开源 SDK。来源摘要和算法模块对应关系见coverage.json，许可证与改动说明见NOTICE。
自定义 SDK 程序
示例用于解释和接口核验，不是可执行任务的边界。用户需要其他模型、数据、算法步骤、梯度或后端时，按原生 SDK 工作台在固定环境中编写并执行自定义代码；由 Agent 完成程序与工件交付。使用 quantum-algorithms 环境定位相关 SDK，保留本算法的数学假设与数值误差说明。
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.

quantum-qfi is a skill published in the GitHub repository xi-zhao/OpenQuantum (75 stars, last pushed yesterday), licensed MIT. It adds 52 tokens to every session and 850 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 2026-09-25.
