# pdf-viewer agent skills for Claude Code, Cursor and RevampKey

> Ready-made pdf-viewer playbooks for AI agents: read and annotate a PDF with AI, save changes to an open PDF. Free SKILL.md files for Claude Code, Cursor and Codex, or one click in RevampKey.

## Skills

- [Work with PDFs in the viewer](https://revampkey.com/marketplace/pdf-viewer-5f8ba9/skills/essentials.md): Finds the right PDF, shows it in the viewer, and reads or edits it step by step. It asks before saving or changing anything in the document.
- [Read and annotate a PDF with AI](https://revampkey.com/marketplace/pdf-viewer-5f8ba9/skills/read-and-annotate-pdf.md): Opens a PDF in the viewer, reads its content and structure, and returns a summary and page-referenced notes without changing the file.
- [Save changes to an open PDF](https://revampkey.com/marketplace/pdf-viewer-5f8ba9/skills/save-pdf-changes.md): Reviews the pending edits in your open PDF, lists them with destructive changes first, and saves only the set you approve. It then re-reads the file to check the result.

### What is a pdf-viewer agent skill?

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

### Do the pdf-viewer 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 pdf-viewer.

### 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 pdf-viewer; elsewhere you copy the folders into your project or skills directory.

### Do I need the pdf-viewer MCP server too?

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