📄 Description

Structural Changes

  • Upgrade to latest LangChain alpha release a14
  • Consolidate logic in Middleware files
  • Much more comprehensive tests for Subagents and Filesystem
  • Use the PlanningMiddleware from LangChain instead of a separate implementation

Features

  • Add long-term memory to filesystem
  • Add long-tool interceptor

Breaking Changes

  • Updated the create_deep_agent signature to closely mimic that of create_agent (prompt -> system_prompt)
  • async_create_deep_agent has been folded into create_deep_agent
  • graph -> runnable in CompiledSubAgent schema
