## Skills

- [Use Alpha Vantage data with AI, safely](https://revampkey.com/marketplace/alpha-vantage/skills/essentials.md): Sets up how the assistant reads Alpha Vantage market and fundamental data: it confirms the symbol, date window and asset type first, keeps responses small, and reports rate-limit or key problems instead of guessing. The connector is read-only, so it never changes your account.
- [Commodity price trend check](https://revampkey.com/marketplace/alpha-vantage/skills/commodity-price-trend-check.md): Checks whether Brent, coffee, copper, corn or aluminum is rising, falling or flat over a chosen window, and how it compares with the others. It states the window and separates a real trend from normal month-to-month noise.
- [Review a company's fundamentals with AI](https://revampkey.com/marketplace/alpha-vantage/skills/equity-fundamentals-review.md): Pulls a listed company's overview, balance sheet and cash flow statement, checks them against each other, and flags debt build-up, shrinking margins or earnings that cash does not support. It reads the figures only and never changes anything.
- [Sliding-window stability report for a price series](https://revampkey.com/marketplace/alpha-vantage/skills/sliding-window-analytics-report.md): Measures rolling volatility, return stability and regime shifts over time using sliding and fixed window analytics, then writes a short report on whether a stock's behaviour is stable or changing. The connector is read-only, so nothing is changed.
- [Screen a stock's technical indicators with AI](https://revampkey.com/marketplace/alpha-vantage/skills/technical-indicator-screen.md): Reads a symbol's trend, momentum, volatility and volume indicators together and returns a one-page read that calls out where the signals agree and where they conflict. It only reads data and never places trades.

### What is a Alpha Vantage agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each Alpha Vantage skill describes one job, which Alpha Vantage tools to use in which order, what to check first and when to stop and ask you.

### Do the Alpha Vantage skills change anything on their own?

4 of the 5 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in Alpha Vantage.

### Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect Alpha Vantage; elsewhere you copy the folders into your project or skills directory.

### Do I need the Alpha Vantage MCP server too?

Yes. The skills tell the agent how to do the work; the Alpha Vantage MCP server gives it the tools to do it. The Alpha Vantage MCP setup guide covers every client.
