TWMD Skills — put TWMD inside your AI

Six official skills. Install them and your AI becomes a TWMD answer-desk — and drops Taiwan market data into whatever you already use.

Install

One command installs all six. The repository is public and open source — read any skill before you install it.

$
npx skills add https://github.com/Anthonychiu1205/twmd-skill

The six skills

Each carries its own trigger description, so your AI reaches for the right one on its own — ask about FinMind and it loads the migration skill, ask about backtrader and it loads the backtesting one. To install just one, copy its command.

  • twmd-taiwan-market-dataEveryone / first time

    Start from zero — paste it into your AI and it becomes your Taiwan-market data guide: creating a key, pulling your first row, which of the 82 datasets answers your question, and what to do when a call comes back with an error.

    $
    npx skills add https://github.com/Anthonychiu1205/twmd-skill --skill "twmd-taiwan-market-data"
  • twmd-quant-recipesQuants / researchers

    A factor library that runs as it comes — monthly-revenue YoY momentum, institutional investor flows, valuation screens (PER/PBR/yield), multi-factor ranking. Every one is built point-in-time against look-ahead bias, so your backtest is not cheating from day one.

    $
    npx skills add https://github.com/Anthonychiu1205/twmd-skill --skill "twmd-quant-recipes"
  • twmd-integrationEngineers

    Production-grade access in one pass — retry and backoff, pagination and async built in, landing straight into DuckDB / Postgres / BigQuery / Snowflake, pipelines for Airflow / dbt / Dagster, and clients down to Go, Java, Ruby and R.

    $
    npx skills add https://github.com/Anthonychiu1205/twmd-skill --skill "twmd-integration"
  • twmd-migrationsSwitching providers

    Move over from FinMind, yfinance, TEJ or a broker API (SinoPac, Fugle) with almost no code change — drop-in compatibility layers let your existing pipeline run on TWMD as it stands.

    $
    npx skills add https://github.com/Anthonychiu1205/twmd-skill --skill "twmd-migrations"
  • twmd-backtesting-platformsBacktesting / trading

    backtrader, vectorbt, zipline, QuantConnect and MT4/MT5 all connect, each with the survivorship-bias and point-in-time cautions attached — so a backtest does not look good and then fall apart live.

    $
    npx skills add https://github.com/Anthonychiu1205/twmd-skill --skill "twmd-backtesting-platforms"
  • twmd-bi-and-agentsAnalysts / agent builders

    Excel, Sheets, Power BI and Tableau pull it straight in; LangChain, LlamaIndex, function-calling and OpenBB connect in one step — building a dashboard or building an agent, Taiwan market data is right there.

    npx skills add https://github.com/Anthonychiu1205/twmd-skill --skill "twmd-bi-and-agents"

No CLI? Paste it instead

  • Every skill is a single SKILL.md file. Open one in the repository and paste it into ChatGPT or Claude — no install step, same content.
  • For a shorter, general-purpose starting point, /start.txt is the onboarding pack: paste it into any AI and it can walk you from zero to your first request.
  • Repository: https://github.com/Anthonychiu1205/twmd-skill

What a skill does not change

  • A skill is instructions, not access. It still calls the same REST API with your own key, on your own plan, and spends the same quota.
  • It cannot invent coverage. Where a dataset has gaps the API reports data_gaps, and the skills are written to surface that rather than fill it in.
  • Not investment advice — the skills produce data and code, never buy/sell/hold calls.
