# Doppels Agent Skills: Teach Your AI to Freeze Sessions

> Agent skills extend Claude, Cursor, and Codex with Doppels capabilities — install them once and trigger freeze from any agent conversation.

Agent skills are sets of instructions that extend your AI agent with Doppels capabilities. Install a skill once and your agent knows how to freeze any working session into a replayable YAML Capability and Recipe — no re-prompting, no re-explaining, no re-doing. Skills live alongside your agent configuration and activate automatically whenever you ask for a freeze.

## Available skills

| Skill           | Status      | What it does                                                          |
| --------------- | ----------- | --------------------------------------------------------------------- |
| `doppel-freeze` | Active      | Capture an agent session as a local deterministic Capability + Recipe |
| `doppel-use`    | Coming soon | Invoke a Capability from inside an agent session (blocked on MCP)     |

## Installation

Install skills using the `npx skills add` command. You only need to do this once per machine or project.

<CodeGroup>
  ```shell Install all skills theme={null}
  npx skills add doppelshq/doppels
  ```

  ```shell Install just the freeze skill theme={null}
  npx skills add doppelshq/doppels --skill doppel-freeze
  ```

  ```shell Install for specific agents theme={null}
  npx skills add doppelshq/doppels -a claude-code -a cursor -a codex
  ```
</CodeGroup>

## Supported agents

Skills work with the following agents and editors:

* **Claude** (`claude-code`)
* **Cursor**
* **Codex**
* **OpenCode**
* **Windsurf**
* **VS Code**

## About `doppel-use`

<Note>
  `doppel-use` — the skill that lets your agent invoke a frozen Capability mid-session — is currently blocked on the Doppels MCP server implementation. It is not yet available. Watch the [GitHub repository](https://github.com/doppelshq/doppels) for updates.
