# Sigma agent skills for Claude Code, Cursor and RevampKey

> Ready-made Sigma playbooks for AI agents: answer data questions from Sigma with AI, build a Sigma workbook from your findings. Free SKILL.md files for Claude Code, Cursor and Codex, or one click in RevampKey.

## Skills

- [Use the Sigma connector safely with AI](https://revampkey.com/marketplace/sigma/skills/essentials.md): Confirms your Sigma organisation and scope, finds and describes the right data, runs bounded queries and reports results with their limits. It asks before switching workspace or building anything.
- [Answer data questions from Sigma with AI](https://revampkey.com/marketplace/sigma/skills/data-question-answering.md): Finds the right Sigma document or data source for a business question, runs a bounded query and reports the answer with its source, scope and caveats. Read-only: it does not change anything in Sigma.
- [Build a Sigma workbook from your findings](https://revampkey.com/marketplace/sigma/skills/workbook-build-from-findings.md): Turns an agreed analysis into a new Sigma workbook. It drafts the structure first and creates nothing until you approve the plan.

## Install

- RevampKey: connect Sigma at https://revampkey.com/marketplace/sigma; the skills come with it.
- Any Agent Skills tool, into the current project:

```bash
for s in essentials data-question-answering workbook-build-from-findings; do

### What is a Sigma agent skill?

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

### Do the Sigma skills change anything on their own?

3 of the 3 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 Sigma.

### 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 Sigma; elsewhere you copy the folders into your project or skills directory.

### Do I need the Sigma MCP server too?

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