EternalSoul.md gives an AI agent a lasting identity. It merges the agent's personality, identity, memory and notes about its user into a single file, encrypts it with PGP and keeps a backup, so the agent can be restored later and still remember you.
This means your preferences, sense of humour and working style carry over even if the agent is reset or moved. Agents can be set up by reading a quickstart skill file from the site. A free way to start is available.
