# Deep Agent

`cortavyn-deep` composes Graph, Chat, and the model API into a portable deep-agent harness. It provides a thread-isolated virtual workspace, task planning, todos, persistent memory, skills, subagents, optional MCP sources, and approval-aware writes.

`invoke` and `resume` run through an internal `StateGraph`. A pending approval is therefore a durable graph interrupt rather than an in-process callback.

Start with the [Deep Agent quickstart](/deep-agent/quickstart).
