Durable local memory for Hermes agents: SQLite FTS5 facts with cited, explainable recall; a Markdown vault with knowledge-graph export and an interactive visual graph; and turn-prefetch context injection with reason tokens. Write policy auto-redacts high-confidence secrets at write time (other PII types are warn-only findings) and stored-content injection screening flags and warns on recall and prefetch payloads (flag-and-warn, fail-open by design, not a blocking filter). Includes a 34-command CLI, destructive-op gates with automatic backups, and an append-only audit log.

## Good to know before installing

All memory data (vault markdown, memory.db, index.db, backups) stays local under HERMES_HOME/entropicmem/; a shared publish DB defaults to HERMES_HOME/entropicmem-shared/. The CLI init command appends ENTROPICMEM_* settings to HERMES_HOME/.env (append-only). Vector embeddings are off by default; only with embeddings_enabled: true (provider) or ENTROPICMEM_EMBEDDINGS=1 / query --semantic (CLI) and the optional sentence-transformers extra installed does first use download all-MiniLM-L6-v2 weights from huggingface.co; otherwise the provider has no network egress. The CLI ingest command fetches a user-supplied URL; CLI graph export writes to ./export in the cwd by default and its HTML loads D3/marked from d3js.org and cdn.jsdelivr.net when opened; CLI graph serve starts a loopback HTTP server. entropicmem_patch_core edits the plugin's own Core-memory markdown (Persona/User_Profile), not Hermes core, and is off by default.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install entropicmem
```

2. Said no? Turn it on later:

```bash
hermes plugins enable entropicmem
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
