Documentation

README

Excerpt

mnemon

Use mnemon when durable memory can materially improve continuity across Hermes sessions. Hooks may inject recalled context before an LLM call, but the agent decides what is worth storing.

Workflow

Recall when prior decisions, preferences, or facts may affect the current task: mnemon recall "<query>" --limit 10
Remember only stable, reusable knowledge: mnemon remember "<fact>" --cat <cat> --imp <1-5> --entities "e1,e2" --source agent
Link related memories after reviewing candidates from remember: mnemon link <id> <candidate> --type <causal|semantic> --weight <0-1>

This is the opening of the README. Read the full README on GitHub.
