What problem does it solve? Hermes Agent's built-in memory (MEMORY.md / USER.md) only holds 10-15 facts and cannot support long-term cross-session memory, automatic fact extraction, semantic search, or knowledge graphs. This Skill guides you through evaluating, installing, and configuring external memory providers. ## Core Features & Use Cases - Provider Comparison: Compares 8 memory providers (Honcho, Mem0, OpenViking, Hindsight, Holographic, RetainDB, ByteRover, Supermemory) by cost, use case, and server requirements. - Guided Setup: Provides CLI commands (hermes memory setup, status, off) and config file locations for each provider. - Pitfall Documentation: Covers known issues including context_length overrides, DeepSeek's missing embeddings API, Mem0 v2.x filter syntax, ChromaDB write locks, and FreeLLM 429 routing errors. - Use Case: When you need Hermes to remember user preferences across sessions, run the setup flow to install Mem0 OSS with Qdrant as a free local vector store. ## Quick Start Ask the agent to set up long-term memory for Hermes using a free local provider like Mem0 with Qdrant.
