📄 Description

Summary

MemoryMiddleware (new)

  • Loads persistent context from AGENTS.md files following the agents.md spec
  • Always-on injection into system prompt (unlike skills which are on-demand)
  • Supports multiple sources (e.g., user-level + project-level)
  • Content wrapped in XML tags (<user_memory>, <project_memory>)

Usage

Memory (always-on context)

memory = MemoryMiddleware(
    backend=FilesystemBackend(root_dir="/"),
    sources=[
        {"path": "~/.deepagents/AGENTS.md", "name": "user"},
        {"path": "./.deepagents/AGENTS.md", "name": "project"},
    ],
)

- Sources are loaded in order, combined into prompt
- Each wrapped in XML: <user_memory>, <project_memory>
- Missing files skipped silently
- File format: plain markdown
