From the SKILL.md

# longbridge-graham-screener Prompt-only batch screener. Given a market or index universe, applies Graham's six hard filters (NCAV, PE, PB, dividend yield, debt coverage, earnings stability), scores each name on a 100-point static + dynamic composite, and returns a ranked list of stocks meeting Graham's quantitative criteria, with Graham buy lines, holding-period expectation, and value-trap warnings. > **Response language**: match the user's input language — Simplified Chinese / Traditional Chinese / English. ## When to use - *"港股里现在有没有 NCAV<1 的股票"* / *"港股裡現在有沒有 NCAV<1 的股票"* / *"any HK stocks with NCAV < 1"* - *"给我 A 股 PE 最低的 20 只股票，格雷厄姆标准"* / *"給我 A 股 PE 最低的 20 隻股票，格雷厄姆標準"* / *"top 20 lowest-PE A-shares by Graham standard"* - *"帮我筛一下符合格雷厄姆防御型投资者条件的美股"* / *"幫我篩一下符合格雷厄姆防禦型投資者條件的美股"* / *"screen US stocks meeting Graham defensive-investor rules"* - *"沪深300里的烟蒂股"* / *"滬深300裡的煙蒂股"* / *"cigar-butt names in CSI 300"* - *"每周更新港股 NCAV 排行榜"* / *"每週更新港股 NCAV 排行榜"* / *"weekly HK NCAV leaderboard"* For single-stock deep diagnostic use `longbridge-graham-stock-analysis`. For broader low-PE / low-PB / high-ROE value (not NCAV-centric) use `longbridge-value-screen`. For high-dividend-only screens

How do I install it?

Run `npx skills add majiayu000/claude-skill-registry --skill longbridge-graham-screener --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
