robustness-check

robustness-check is a skill for Claude Code from Travisun/Opptrix. It costs 78 tokens per session (827 once invoked), scanned A, original, Apache-2.0.

A strategy-testing workflow that changes selected parameters around a baseline and compares the results. This checks whether a strategy still behaves similarly when its settings are slightly different.

In plain words
What is it for?
Use it to test parameter variations such as time windows or thresholds, compare the resulting returns and drawdowns, and identify where the signal changes direction.
Why use it?
It helps reveal conclusions that depend on one unusually favourable parameter choice. It also makes clear that a stable test result is not the same as a guarantee that the strategy can be traded successfully.

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

robustness-check 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 5d 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

稳健性检验

何时使用

用户要验证策略/信号在参数扰动下是否仍站得住,而非单次点估计回测。边界:单次回测用 @skill:run-backtest;因子研究用 @skill:factor-research

分析架构(投研方法)

  • 问题/假设:结论是否依赖某一组「刚好好看」的参数?
  • 证据清单verify_instrument_strategy 结果、run_backtest(若适用)、opptrix_run 扰动网格输出
  • 多维交叉验证:基准参数 vs 邻域网格;胜率/回撤分布是否塌缩
  • 结论与不确定:稳健≠可交易;网格设计本身可过拟合
  • 风险与缺口:无法批量回测、标的数据不足
  • 事实 | 假设 | 推断 分栏

数据维度

维度 取数方向 缺失时
标的与策略 ask_user 先确认
基准验证 verify_instrument_strategy 说明工具失败原因
回测对照 run_backtest 仅做信号层验证
扰动网格 opptrix_run(可 workspace_write 固化表) 手工列出少量扰动并标明非穷尽
交付 list_web_vendorcreate_web 可跳过口头要点

步骤

  1. 确认基准参数与扰动维度(窗口、阈值、阈值等)。
  2. 跑基准 verify_instrument_strategy(及可选 run_backtest)。
  3. 扰动网格:用 opptrix_run 批量计算;结果表可 workspace_write
  4. 汇总稳健性:哪些参数邻域结论同向/翻转;事实与推断分栏。
  5. 交付网页(默认):热力/表格用本地 vendor;见 @skill:create-web

网页报告建议目录

  1. 检验范围与基准参数
  2. 基准验证/回测结果
  3. 扰动网格设计与结果表
  4. 稳健性结论(事实 / 推断)
  5. 过拟合与缺口
  6. 免责声明

禁止

  • 荐股;编造网格结果
  • 只展示「最好看」的一组参数隐瞒其余
  • 禁止无交付就结束

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.
