A股选股器

当用户需要查找股票、上市公司、行业成分股、指数成分股，或者根据市场、估值、财务、行业等方面的限制条件（如市盈率、净资产收益率、价格、增长情况、成交量、行业状况、董事会情况或特定概念等）来推荐股票时，可以使用此技能进行 Eastmoney MX 基于条件的股票筛选和宇宙搜索功能。但请勿用于单只股票的报价或财务数据查询（请使用 mx-data），新闻/事件研究（请使用 mx-search），观察清单中的操作（请使用 mx-zixuan），或模拟交易操作（请使用 mx-moni）。

mx-xuangu

Use mx_xuangu.py to convert natural-language screening conditions into Eastmoney MX stock-screening queries and CSV outputs.

Trigger Boundaries

• Use for "筛选/找出/选出/有哪些股票/成分股/板块内/行业内/满足条件" requests.
• Use for compound filters such as price, PE/PB, ROE, revenue/profit growth, market cap, industry, board, concept, region, dividend, and recent performance.
• Use for constituent lookup of sectors, themes, and indexes.
• Do not use for exact data of one entity; use mx-data.
• Do not present screening output as personalized investment advice unless the user explicitly asks for analysis.

Inputs

• Required: universe or condition. If the universe is missing, default to A-shares only when the user's wording implies China/A-share context; otherwise ask.
• Clarify ambiguous constraints that change the result, such as "低估值", "近期", or "龙头".
• Require MX_APIKEY. Optional: set MX_OUTPUT_DIR; otherwise output goes to ~/.codex/skills-output/mx_data/output.

Workflow

1. Convert the request into one concise natural-language screening query.
2. Keep the query specific: universe + filters + ordering/limit if requested.
3. Run:

bash

python /Users/lu/.codex/skills/mx-xuangu/mx_xuangu.py --query "市盈率小于20且ROE大于15%的银行股"

4. Inspect row count, CSV path, and description file.
5. If raw field interpretation matters, read references/result-fields.md.
6. Report the matching count, key filters, top rows, and generated file paths.

Output Contract

• Show the parsed screening condition and final match count.
• Include a compact table of representative results when the list is long.
• State that results are data-screening candidates, not buy/sell advice.
• Mention if a condition appears too strict or returned zero rows.

Failure Handling

• Zero rows: suggest relaxing one or two specific constraints.
• Parser failure: rewrite the query with explicit operators and units.
• Too many rows: add ranking, top N, sector, market, or date constraints.
• API/auth/rate-limit errors: report the code and stop.

Validation

• Use evals/evals.json to check that screening prompts trigger this skill and single-security data/news prompts route elsewhere.
