hermes-next 0.2.0

Next-generation memory provider for Hermes Agent — fusing OpenViking vector storage with MemOS cognitive engine

Hermes Next

Next-generation memory provider for Hermes Agent.

Hermes Next fuses OpenViking vector storage with a Python-native MemOS cognitive engine, giving Hermes Agent agents persistent,结构化记忆能力。

Features

• OpenViking Backend — Long-term vector storage, semantic retrieval, session management
• MemOS Cognitive Pipeline — L1 Trace capture → reward backpropagation → L2 Policy induction → L3 World Model → Skill crystallization
• Python Native — Zero bridging overhead, runs in-process
• Local SQLite Cache — FTS5 full-text search + numpy-based cosine similarity, zero dependencies beyond stdlib
• Fusion Retrieval — 6-step pipeline combining semantic search, full-text search, policy matching, timeline, recency boost, and MMR diversification

Installation

pip install hermes-next

Requires Python 3.10+ and a running OpenViking server (v0.3.22+).

Configuration

Create a hermes-next.yaml in your config directory:

openviking:
  base_url: "http://localhost:1933"
  api_key: null

cache:
  path: "~/.hermes-next/cache.db"
  enable_fts: true

agent:
  name: "default"

Or set environment variables:

export HERMES_NEXT_OV_URL="http://localhost:1933"
export HERMES_NEXT_CACHE_PATH="~/.hermes-next/cache.db"

Usage with Hermes Agent

from hermes_next import HermesNextProvider

provider = HermesNextProvider()
provider.initialize(session_id="my-session")

# The provider handles prefetching, storage, and retrieval automatically
context = provider.prefetch("What did we discuss about RAG?")
print(context)

Or via CLI:

hermes agent --memory-provider hermes-next

Tools

The provider exposes these tools to the agent:

Tool	Description
memos_search(query, k)	Semantic search across traces
memos_get(trace_id)	Read a specific trace
memos_timeline(limit)	Recent activity timeline
