factor-exposure

factor-exposure is a skill for Claude Code, Codex from Travisun/Opptrix. It costs 81 tokens per session (1,053 once invoked), scanned A, original, Apache-2.0.

A portfolio factor-exposure review describes how a portfolio is distributed across industries, individual holdings, styles, and concentration. It is a structural review, not the official Barra risk model.

In plain words
What is it for?
Use it to review holdings or watchlists, measure top-position and industry concentration, and interpret available style indicators.
Why use it?
It makes hidden concentration and style tilts easier to see, including cases where the portfolio differs from how the investor thinks it is positioned.

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

factor-exposure 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 3d 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

因子暴露(组合结构诊断)

何时使用

用户要看组合或关注列表相对行业/风格/集中度的暴露结构,而非单只个股尽调或完整回测。边界:因子有效性检验用 @skill:factor-research;扰动稳健性用 @skill:robustness-check

能力声明:本技能基于 analyze_portfolio 与持仓摘要做结构暴露诊断不是官方 Barra / 商业风险模型(无完整因子协方差与特异风险分解)。

分析架构(投研方法)

  • 问题/假设:组合是否过度集中于少数行业/个股?风格倾斜是否与用户认知一致?
  • 证据清单:持仓/关注列表、组合摘要、analyze_portfolio 诊断输出
  • 多维交叉验证:权重集中度 vs 收益贡献(若可得);行业权重 vs 个股头部
  • 结论与不确定:暴露为结构事实;「风险过高」属推断
  • 风险与缺口:无持仓、价格刷新失败、跨市场行业口径不一致
  • 事实 | 假设 | 推断 分栏:持仓权重为事实;代理风格标签为假设;风险含义为推断

数据维度

维度 取数方向 缺失时
范围 ask_user:持仓 / 关注列表 先确认再分析
列表与持仓 get_watchlist / get_portfolio_holdings 说明为空,给下一步
摘要 portfolio_summary 用明细自行汇总并标注
诊断 analyze_portfolio 省略诊断章,仅做集中度表
标的核对 search_instruments / get_instrument_snapshot 跳过价格刷新
交付 list_web_vendorcreate_web 用户只要口头要点时可跳过

步骤

  1. 确认范围:持仓、关注列表或用户给定代码清单。
  2. 取数:列表/持仓 → 摘要 → analyze_portfolio
  3. 结构化暴露:行业/个股集中度、头部权重、可得的风格代理字段;显式声明非 Barra
  4. 交叉验证:摘要指标 vs 明细加总;事实/假设/推断分栏。
  5. 交付网页(默认)list_web_vendorcreate_web(权重饼图/条形图用本地 vendor);已有则 read_web / update_web。完整 HTML 规范见 @skill:create-web

网页报告建议目录

  1. 范围、时效与能力声明(非 Barra)
  2. 组合摘要 KPI
  3. 行业/个股暴露表
  4. 集中度与头部持仓
  5. 诊断要点(事实 / 推断分栏)
  6. 风险、缺口与后续观察
  7. 免责声明(无调仓建议)

禁止

  • 荐股、调仓、目标仓位;编造暴露数字
  • 禁止把结果写成「官方 Barra 因子暴露」或商业风险模型输出
  • 禁止无交付就结束(默认须有 web 产物,除非用户明确只要口头要点)
  • 降级数据须标注可信度受限

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.
