# Customer.io agent skills for Claude Code, Cursor and RevampKey

> Ready-made Customer.io playbooks for AI agents: review Customer.io campaign performance with AI, audit your Customer.io data schema with AI. Free SKILL.md files for Claude Code, Cursor and Codex, or one click in RevampKey.

## Skills

- [Use the Customer.io connector safely](https://revampkey.com/marketplace/customer-io/skills/essentials.md): Guides the assistant to confirm the right workspace, read before it writes, and wait for your explicit yes before sending, changing or deleting anything in Customer.io.
- [Review Customer.io campaign performance with AI](https://revampkey.com/marketplace/customer-io/skills/campaign-performance-review.md): Reviews the recent performance of a named Customer.io campaign or broadcast, separating real results from noise and flagging anomalies such as bounce or unsubscribe spikes. It reads the data only and asks before changing anything.
- [Audit your Customer.io data schema with AI](https://revampkey.com/marketplace/customer-io/skills/data-schema-audit.md): Checks whether your Customer.io workspace has the fields a question needs, flagging missing, duplicate or mistyped attributes before you build on them. It is read-only and asks before changing anything.

## Install

### What is a Customer.io agent skill?

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

### Do the Customer.io skills change anything on their own?

2 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 Customer.io.

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

### Do I need the Customer.io MCP server too?

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