How Hermes Agent Persists Memory, Skills and Safety Decisions Across Sessions
alex_verem · x · 2026-07-26
An in-depth look at Hermes Agent’s persistence and safety model argues that the real risk is not only catastrophic file deletion, but the quieter problem of agents gradually writing their own long-term profile and skills to disk.
- The article walks through a reported incident and then explains Hermes’ default configuration, including memory.writeapproval = false, skills.writeapproval = false, and guardagentcreated = false.
- It argues that session state, MEMORY.md, USER.md, and SKILL.md act as layered memory: some facts survive every session, some are distilled into environment conventions, and some become permanent behavior after a correction is accepted.
- The key warning is that users may lock down the wrong boundary: Docker or other backends isolate the host, but local shells, write guards, and approval lists still leave room for unsafe behavior if the agent can act through the terminal.
- The post frames self-improvement as a permissioned workflow, not a built-in feature, and says that the agent only permanently changes after a human correction is written back into its skills or memory files.
