Investor Skills is an open-source library that turns durable investing judgment into portable, structured formats. It collects how great investors think, filter opportunities, size risk, and act under uncertainty — then structures those patterns so humans can study them and AI finance agents can app
Investor Skills is an open-source library of portable, structured investment judgment systems packaged as AI agent skills. It codifies how legendary investors like Buffett, Soros, Livermore, and dozens of others analyze opportunities, size positions, and manage risk into reusable SKILL.md packages that AI finance agents can execute. Each skill defines triggers, inputs, decision processes, and guardrails alongside optional INVEST.md schema files containing structured signals, filters, and risk parameters. The skills work with Claude Code, Cursor, ChatGPT, or any agent harness that can read markdown instructions, and are optimized for Questflow's AI finance agent platform.

investorskills — FAQ
What is Investor Skills?+
Investor Skills is an open-source library that packages the judgment systems of great investors (Buffett, Soros, Livermore, etc.) into structured SKILL.md files that AI agents can load and apply. Each skill defines when to use it, what inputs it needs, how to process decisions, and what guardrails to follow.
How do I install an investor skill?+
You can install all skills with 'npx skills add https://github.com/questflowai/investorskills' or a single skill with the --skill flag. Alternatively, copy any skills/<skill-name>/SKILL.md file directly into your agent's skills directory or paste it into a Claude/ChatGPT conversation.
Which AI clients work with Investor Skills?+
The skills work in Claude Code, Cursor, ChatGPT, Codex, OpenCode, or any agent harness that can read markdown instructions. They are optimized for Questflow's AI finance agent platform but remain portable plain-text packages.
Do I need API keys or paid subscriptions?+
The open-source skills in this repo are free under MIT license and require no API keys. Questflow offers additional exclusive closed-source skills distilled from real trader execution, which are available to paid members on their platform.
What's the difference between SKILL.md and INVEST.md?+
SKILL.md is the agent interface that defines when and how to use the skill. INVEST.md is an optional structured schema file containing the detailed investment system (signals, filters, sizing, risk rules) referenced by the skill. Simple skills embed everything in SKILL.md; larger models separate the schema into INVEST.md.
Can I create my own investor skills?+
Yes, use the copyable templates in templates/skill.template.md and templates/invest.template.md to build new skills. Define the investor's triggers, universe, signals, filters, sizing rules, risk parameters, and guardrails, then add the skill to your agent's directory.
