About Hermes Agent

Hermes Agent is an open-source autonomous AI agent that runs on your server and grows smarter over time. It’s designed for developers, ML engineers, and IT ops teams who want a persistent assistant that remembers context, builds reusable skills, and stays reachable across messaging platforms.

Key Features

It focuses on long-running memory, automated skill creation, and cross-platform reach to support multi-step tasks and research across your tools:

Persistent Memory

Remembers preferences, projects, and environment across sessions so you don’t re-explain context each time.

Automated Skill Creation

When Hermes solves a problem, it writes a reusable skill document that remembers the approach; skills are searchable, shareable, and compatible with the agentskills.io standard.

Multi-Platform Gateway

Connects Telegram, Discord, Slack, WhatsApp, Signal, and CLI from a single gateway; supports voice memos and cross-platform continuation.

Parallel Sub-Agents

Spawns isolated sub-agents for parallel workstreams; each gets its own conversation and terminal, enabling efficient parallel execution and RPC-based handoffs.
