Mnemosyne Native Plugin

Native Hermes plugin for persistent memory that uses the pre_llm_call hook to inject context automatically, similar to Honcho but fully local with SQLite.

Architecture

• Type: Native Hermes Plugin (not just a skill)
• Hook: pre_llm_call - injects context before each LLM call
• Storage: SQLite database (~/.hermes/mnemosyne/data/)
• Location: ~/.hermes/plugins/mnemosyne/
