What Mnemon does

Mnemon is a persistent memory CLI for LLM agents to store facts, recall past knowledge, and link related memories. Use it to import context, manage memory lifecycle, and reduce lost continuity across tasks.

Mnemon is cataloged under AI Engineering on DirSkills. Mnemon comes from a repository tagged agent-framework, agent-memory, ai-agent, ai-tools and claude.

Excerpt

mnemon

Workflow

Remember: mnemon remember "<fact>" --cat <cat> --imp <1-5> --entities "e1,e2" --source agent
- Diff is built in: duplicates are skipped, conflicts are auto-replaced.
- Output includes action (added/updated/skipped), semantic_candidates, and causal_candidates.
Link (evaluate candidates from step 1 using judgment):
- Review causal_candidates: link only when the memories are genuinely causally related.
- Review semantic_candidates: high similarity alone is not enough; skip unrelated keyword matches.
- Syntax: mnemon link <id> <candidate> --type <causal|semantic> --weight <0-1> [--meta '<json>']
Recall: mnemon recall "<query>" --limit 10
