Hermes

  • ID: hermes
  • Store: ~/.hermes/state.db (0.17+) or ~/.hermes/profiles/<profile>/state.db (older builds, one store per profile)
  • Read overrides: DEJA_HERMES_PROFILES_ROOT for the profiles directory, DEJA_HERMES_DB to pin a single store
  • Format: SQLite relational store

A flat messages table, grouped by session_id: role, content, and timestamp

as REAL epoch seconds. Rows with role of tool carry no prose and are skipped, as

are rows with a null content. There is no working directory in the schema, so the

profile name stands in for the project.

  • MCP: mcp_servers in ~/.hermes/config.yaml; deja install hermes-auto also drops a plugin whose pre_llm_call hook injects recall and registers /deja.
  • Resume: Hermes has its own session commands; nothing documented that starts a session from a prompt.
  • Handoff: paste.

Requested in #355.

deja reads this format and nineteen others, and turns what it finds into memory your agents can search. See the harness matrix for what is wired where, or install it and search your own history.
