ch-skills

Open-source skills — shareable & installable.

A personal collection of Claude Code skills. Each skill is a self-contained directory with a SKILL.md manifest plus any supporting files, ready to drop into your own Claude Code setup.

What is a skill?

A skill is a named capability that Claude Code can discover and invoke on demand. Each skill lives in its own folder and declares itself via YAML frontmatter in SKILL.md:

---
name: my-skill
description: One sentence telling Claude when to use this skill.
---

Body content — instructions, workflow, examples.

Claude reads the frontmatter at session start and loads the full body only when the skill is triggered.

Skills in this repo

Skill	Purpose
`meta-prompt`	Turn a vague, conversational task into a high-quality, copy-pastable prompt for another AI (Claude or GPT). Invoked by saying "help me write a prompt", "optimize this for Claude/GPT", or `/mp`.
`marxist-method-for-action`	Rigorous problem-analysis methodology for substantive decisions (housing, career, medical, investment, tech/architecture, debugging, …). Six base principles plus nine Mao-style operational hooks (investigation circle, stakeholder mapping, main-contradiction transition, staged strategy, worst-case wargaming, concentrated main attack, active levers, typical-case deep-dive). Invoked by `/mma` or phrases like 用马哲分析 / 用毛选方法 / 矛盾分析一下 / 实事求是地看.
`industry-chain-research`	产业链研究：从宏观趋势拆解产业链、定位瓶颈环节、找到具体标的、交叉验证风险。在结构化框架里让 AI 做产业链研究员。Invoked by 产业链分析 / 拆产业链 / 瓶颈分析 / 景气度投资 / "帮我拆一下XX产业链".
`intrinsic-value-analysis`	用老唐（唐朝）估值法分析企业内在价值。以巴菲特/格雷厄姆 DCF 思想的工程化简化为骨架：三大前提排雷 → 把好公司当债券 → 三年后合理估值打五折买入。Invoked by 估值 / 内在价值 / "现在能不能买" / "什么价位卖".
`company-analyzer`	Analyze a company through three layers — story, logic, judgment — and deliver a narrative-driven report with a clear take. Invoked by "研究 XX 公司" / "深度分析 XX" / "带我看懂 XX 这家公司" or naming a company alongside investment/career/competition context.
`wechat-feeds`	Maintain a local, incrementally-updated library of WeChat Official Account (公众号) articles as Markdown + a SQLite index, and pull new posts on demand. Bundles a self-contained Bun scraper that drives a logged-in Chrome via a tiny CDP proxy. Invoked by "update my feeds" / "拉一下公众号" / "增量更新公众号文章".

A-share investment research toolkit

A set of composable skills for A-share (A股) stock research. Analysis skills call the data skills; set your own TUSHARE_TOKEN (no credentials are bundled).

Skill	Purpose
`stock-analyzer`	Deep-dive individual stock analysis across 5 dimensions (business, financials, valuation, catalysts, risks) → structured research note with a clear buy/sell/hold thesis and falsification conditions. Invoked by "分析一下XX股票" / "这只股票能不能买".
`technical-analyzer`	Secondary timing tool — MA trend, support/resistance, volume analysis for entry/exit. Never the primary basis. Invoked by "现在能买吗" / "技术面怎么样" / "支撑位在哪".
`valuation-calculator`	Relative valuation: PE/PB/PS historical percentiles, peer-comparison tables, PE/PB-based target prices. Distinct from the DCF-style `intrinsic-value-analysis`. Invoked by "这只股票贵不贵" / "目标价多少".
`industry-chain-mapper`	Build & maintain persistent industry-chain map artifacts (upstream/mid/down, key companies, market share, elasticity ranking). Artifact-focused complement to `industry-chain-research`. Invoked by "梳理一下XX产业链".
`catalyst-tracker`	Forward-looking catalyst calendar (earnings, conferences, policy events) linked to tracked stocks. Invoked by "最近有什么催化剂" / "财报什么时候出".
`news-scanner`	Scan Xueqiu / Eastmoney / 10jqka + web search for investment news by tracked keywords; reports HIGH/MEDIUM signal only. Invoked by "最近有什么新消息" / "扫描一下XX的最新动态".
`tushare-data`	Primary structured A-share data via Tushare Pro — OHLCV, valuation, financial statements, shareholders, forecasts. CLI over the tushare SDK. Requires your own `TUSHARE_TOKEN`.
`stock-market-data`	Free A-share/US market data via AKShare — trading-day checks, index/sector/limit-up-pool/northbound, per-stock daily OHLCV. No token needed.
`financial-data-fetcher`	Financial statements + ETF data (Tushare primary, AKShare fallback/ETFs). Orchestrates the two data skills above.

Installation

Pick whichever fits your workflow:

Option A — install a single skill

git clone https://github.com/Haochenhust/ch-skills.git /tmp/ch-skills
cp -r /tmp/ch-skills/skills/meta-prompt ~/.claude/skills/

Option B — symlink the whole collection

git clone https://github.com/Haochenhust/ch-skills.git ~/code/ch-skills
ln -s ~/code/ch-skills/skills/meta-prompt ~/.claude/skills/meta-prompt

Option C — track upstream and pull updates

git clone https://github.com/Haochenhust/ch-skills.git ~/.claude/skills-ch
# Then symlink individual skills as needed.

After installing, restart Claude Code (or start a new session) so the new skill is picked up.
