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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00093 | $0.01761 |
| Opus 5 | $0.00046 | $0.00881 |
| Sonnet 5 | $0.00019 | $0.00352 |
| Haiku 4.5 | $0.00009 | $0.00176 |
Grade A, and why
lean-qc500-style-screen 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.

LEAN QC500式筛选
方法溯源 QuantConnect LEAN 社区算法/示例思路；本技能是平台工具编排的投研工作流，禁止假装跑完整 LEAN 引擎或输出 LEAN 回测曲线、订单日志冒充引擎结果。实际取数与计算仅限 Opptrix 工具（行情/财务/opptrix_run 沙盒等）。
能力声明（assumption-only）：本技能在非美股（尤其 A 股）上仅为 QC500 风格近似规则，不是 QuantConnect 官方 QC500 成分、也不是「这就是 QC500」。规则、阈值与字段口径须在报告首页声明。完整度：assumption-only。
何时使用
用户要在 A股宽基成分上做流动性/规模启发式筛选，得到可复核候选表（LEAN QC500 风格溯源，非官方 QC500、非美股原版照搬）。默认交付可预览网页。
边界：一般成分条件筛选用 @skill:universe-screen；本技能专指 QC500 风格规则（成交额/市值/排除壳等启发式）。禁止声称输出「官方 QC500 成分」或「这就是 QC500」。
A股适配（默认）
- 默认市场 CN（A股 / 场内 ETF）。用户点名美股/港股再切换，并声明数据口径与微观结构差异。
- 默认取数优先
search_instruments/get_index_constituents/get_sector_*/get_etf_*及 CN 可用指标与行情工具。 - 禁止称「这就是 QC500」：A 股路径仅为「宽基 + 成交额 + 财务/市值」启发式近似，完整度 assumption-only。
- 示例宇宙：
get_index_constituents沪深300 / 中证500 / 创业板指成分；再叠加成交额与财务过滤。 - 微观结构：涨跌停可能导致流动性/成交额失真；融券受限 → 筛选结果只做多头候选，禁止假设可自由做空对冲。
- 代理映射：美股 QC500 官方成分本地不可得 → 用上述指数池近似；不可硬适配处首页横幅 +
ask_user。 - 不可硬适配或数据缺口时：首页横幅写清完整度（assumption-only 或更严）+ 必要时
ask_user。
分析架构（投研方法）
- 问题/假设：在本地可得数据下，哪些标的近似满足「高流动性大盘」筛选？
- 证据清单：指数/板块成分、批量快照、可选财务/市值字段
- 多维交叉验证：规则命中数 vs 表行；缺失字段不得当通过
- 结论与不确定：近似≠官方 QC500；跨市场规则不可直接搬用
- 风险与缺口：无美股专属 QC500 成分源、A 股字段口径差异
- 微观/制度风险：涨跌停钝化、T+1、ST/停牌、融券受限（及相关会计口径差异）；不得按美股连续可成交或自由做空假设叙事
- 事实 | 假设 | 推断 分栏强制
数据维度
| 维度 | 取数方向 | 缺失时 |
|---|---|---|
| 宇宙基底 | get_index_constituents / get_sector_constituents / 用户清单 |
先确认基底 |
| 筛选规则 | ask_user（成交额、市值分位、排除条件等） |
用书面默认启发式并标假设 |
| 批量行情 | batch_instrument_snapshots |
缩小池或降级 |
| 财务/规模 | get_instrument_financials（按需） |
跳过该条件并标明 |
| 交付 | list_web_vendor → create_web |
可跳过口头要点 |
| A股代理 / 市场 | 沪深300/中证500/创业板指 + 成交额/财务启发式 | 横幅 assumption-only；禁止称 QC500；ask_user 确认基底 |
步骤
- 确认默认 CN：标的/宇宙为 A股或场内 ETF（用户点名其他市场再切换并声明差异）。应用涨跌停/T+1/融券受限等微观约束（见 A股适配）。
- 确认市场与基底：指数/板块/自建池；写明非官方 QC500
- 声明近似规则：首页横幅：A 股/其他市场为风格近似
- 拉取成分与快照：应用硬性过滤；缺字段=未知
- 输出候选表：含规则命中统计；入选≠看好
- 交付网页（默认）：见

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.
- 5d ago First seen · 91 lines · 93 tokens per session scan A 456c8e45c941
lean-qc500-style-screen is a skill published in the GitHub repository Travisun/Opptrix (231 stars, last pushed yesterday), licensed Apache-2.0. It adds 93 tokens to every session and 1,761 once invoked, about $0.0005 per session on Opus 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 2026-09-03.
