Is your PR over 500 lines of code?
Yes, but I believe @sarahwooders is ok with this.

Additional Context

• I only tested with chroma for archival data and sqlite for recall data
• To the best of my knowledge, I have migrated everything except:
  • megmpt migrate (I did not touch this)
  • memgpt run (~90% implemented, no test)
    • current bug lies with running “/attach”
    • However, (I believe) all other memgpt run functionalities are working under both a RESTClient or a LocalClient
• Regarding everything else: my tests pass but they override the user’s config
  • just need to find a way to save the user’s configs and credentials at the start of the test, and then reset them accordingly at the end
• If you want to revert my progress on memgpt load, search across the project for “# krishna” or just remove my changes in:
  • cli.py
    • run(), create_default_user_or_exit(), make_default_user_or_exit(),
  • main.py
    • run_agent_loop()
