📄 Description

Port of langchain-ai/deepagents#646 to TypeScript.

Adds MemoryMiddleware that loads persistent context from AGENTS.md files following the agents.md specification. Unlike skills (which are on-demand), memory is always loaded at agent startup and injected into the system prompt.

Changes:

  • Add createMemoryMiddleware in middleware/memory.ts
  • Add memory parameter to createDeepAgent for automatic middleware setup
  • Export MemoryMiddleware from package index
  • Add unit tests for memory loading and prompt injection

Usage:

const agent = createDeepAgent({
  memory: [ "~/.deepagents/AGENTS.md", "./.deepagents/AGENTS.md", ]
});
