What is personal-finance-skill?

personal-finance-skill is a large collection of tools that lets an AI agent act like a personal finance assistant. It is built for the Agent Skills Protocol, a standard that lets tools like this be plugged into AI coding assistants such as Claude Code, Cursor, and Codex, so once installed you can ask the AI in plain language to check your accounts, look at your investments, or review your taxes. The project offers 75 individual tools grouped into 7 extensions. One handles connecting bank accounts and reading transactions through the Plaid service, another handles stock trading through Alpaca, and another connects to Interactive Brokers for portfolio data. A tax focused extension can read tax forms like W-2s, 1099s, and Schedule K-1s and calculate things such as tax liability, tax loss harvesting opportunities, and estimated quarterly payments. Two more extensions pull in market news, economic data, analyst opinions, and social media sentiment from sources like SEC filings, Finnhub, and StockTwits. A core extension underneath all of this normalizes data from every provider into one shared format and stores it. The README stresses that this project tries to avoid the common problem of AI tools making up financial numbers. Calculations like net worth, profit and loss, and tax liability are always done by the actual tool code, never guessed by the AI itself. Every trade, transfer, or tax related action also has to pass a policy check first, and the README states that no live trade can happen without a person explicitly confirming it. Installing it is a single command line call that adds the skill to your AI agent of choice, with an option to target specific agents individually. Because it touches real bank accounts, brokerage accounts, and tax information, this project is aimed at people comfortable connecting sensitive financial accounts to an AI assistant, and it is released under the MIT license, meaning it can be freely used, modified, and redistributed as long as the copyright notice is kept.
