What it does

“Migrates agents from the retired Python Letta server's PostgreSQL database into Letta Code's local backend/App Server. Use when moving legacy agents, message history, and attached memory blocks into the current local backend and converting block memory to Git-backed MemFS Markdown files.”
The author's description, from SKILL.md

Generated summary from the skill's own text

This skill migrates agents, message histories, and memory blocks from the retired Python Letta server's PostgreSQL database into a Letta Code local backend. It converts legacy conversation data to the current format and transforms attached memory blocks into Git-backed MemFS Markdown files, with dry-run preview and atomic transaction handling to prevent data corruption.

When to use it

  • Moving agents from Python Letta v1 server to current Letta Code local backend
  • Preserving agent conversation history and memory during server migration
  • Converting legacy PostgreSQL agent data to local storage format
  • Transferring multiple agents with their complete message archives

When not to

  • When App Server or Letta Code processes are still running against destination
  • If agent IDs from source already exist in destination directory
  • When PostgreSQL database lacks required legacy tables or columns
