Hermes

Overview

Hermes is the agent runtime that PRISM runs on. It runs the skills headlessly and turns a finished, static audit into a live grounded conversation, so the evidence does not just sit in a report, it answers questions. In plain terms it is the engine that does the work behind the scenes.

Key Capabilities

  • Hosts the agents that run the skills and serve their output.
  • Snapshots SOUL.md into a session's system prompt at conversation creation. Editing SOUL only affects new sessions; existing sessions must be deleted to apply a change.
  • Built-in session housekeeping (sessions.auto_prune, set to 7-day retention). See 2026-06-30-cassandra-naming-and-persona.
  • Exposes a bearer-gated API; hermes-prism is host-network so it reaches PRISM on loopback.
  • prism runs on Hermes.
  • cassandra is the agent Hermes hosts and serves.
  • The grounding gate is a Hermes plugin. See 2026-06-28-grounded-report-qa-gate.
