universe-screen

universe-screen is a skill for Claude Code from Travisun/Opptrix. It costs 75 tokens per session (819 once invoked), scanned A, original, Apache-2.0.

A screening workflow that filters the members of a known index, sector, or custom list using stated conditions. The result is a fact table of instruments that meet the supplied rules, not a list of recommended investments.

In plain words
What is it for?
Use it to build a stock universe, apply market or financial filters, count which conditions each instrument meets, and review the resulting candidate table. An index is a predefined group of securities, while a sector is a group of companies in a similar line of business.
Why use it?
It avoids confusing a rule match with an investment opinion. Missing data is shown as unknown instead of being treated as a pass.

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

universe-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.

What it actually says

股票池筛选

何时使用

用户要在已知成分(指数/板块)或自建池上按条件筛选,得到可复核的候选表。边界:这是筛选事实表,不是荐股池、回测结果或「明日必涨名单」。单票信号诊断用 @skill:instrument-signals;本技能只输出条件命中表,入选≠看好。

分析架构(投研方法)

  • 问题/假设:在给定宇宙与硬性约束下,哪些标的满足条件?
  • 证据清单:成分列表、批量快照、可选财务字段
  • 多维交叉验证:条件计数 vs 表行数;缺失字段不得当通过
  • 结论与不确定:入选≠看好;条件可被操纵
  • 事实 | 假设 | 推断 分栏:筛选项为假设/规则;表内行情为事实

数据维度

维度 取数方向 缺失时
宇宙 get_index_constituents / get_sector_constituents / get_sector_list 用户给代码清单
筛选条件 ask_user 先确认硬性条件
批量行情 batch_instrument_snapshots 降级逐个或缩小池
财务过滤 get_instrument_financials(抽样或必要字段) 跳过该条件并标明
交付 list_web_vendorcreate_web 可跳过口头要点

步骤

  1. 确认宇宙与条件(硬性/软性分开)。
  2. 拉取成分批量快照
  3. 应用过滤:缺字段记「未知」而非通过。
  4. 输出候选表 + 条件命中统计;明确「非荐股」。
  5. 交付网页(默认):可筛选表格;见 @skill:create-web

网页报告建议目录

  1. 宇宙、条件与时效
  2. 成分来源说明
  3. 筛选结果表
  4. 条件命中统计与数据缺口
  5. 事实 / 推断分栏(禁止写成推荐清单)
  6. 免责声明(非荐股池)

禁止

  • 把筛选结果包装成荐股池、目标价或仓位建议
  • 编造成分或快照字段
  • 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.
