Tokens, turns and time describe resource use, not a dollar price.
One of 6 test cases the skill fixed. Same model, same prompt, with and without the skill.
When running Mem0 with default out-of-the-box local configuration without external cloud parameters, where are the vector store embeddings and interaction history database stored by default?
| Checked | Without skill | With skill |
|---|---|---|
| The response identifies Qdrant on disk at /tmp/qdrant as the default vector store location. | Missed | Passed |
| The response identifies SQLite at ~/.mem0/history.db as the default history database location. | Passed | Passed |
The instructions your model reads when the skill loads.
Production-grade memory layers for AI agents that persist context across sessions.
| Need | Tool | Why |
|---|---|---|
| Simple memory for any agent | Mem0 | Open-source, Python SDK, minimal setup |
| Claude Code agent memory | claude-mem | Automatic hooks, 3-layer retrieval |
| Enterprise/self-editing memory | Letta (MemGPT) | Agent-driven memory management |
| Custom memory | RAG + state management | Full control |
