Hermes Agent Go: developer tool for Hermes Agent

What Hermes Agent Go does

The README states that the Go version delivers the same functionality as the Python original in 29,441 lines across 126 Go files, against 183K lines in Python, and compares a 23 MB binary with roughly 500 MB for a Python install with its environment. It lists 50 registered tools, 15 platform adapters (including Telegram, Discord, Slack, WhatsApp, Signal, Email and Matrix), 7 terminal backends, 77 bundled skills and 28 test files.

Other listed features include SQLite session storage with FTS5 search, context compression, smart model routing to cheaper models, a fallback chain, subagent delegation through goroutines with a maximum of 8 concurrent, cron scheduling, an MCP client over stdio and SSE, profiles, plugins, and an ACP server for VS Code, Zed and JetBrains. It supports OpenAI-compatible APIs and the Anthropic Messages API with prompt caching. You build it from source with Go 1.22 or newer, with make, or in Docker.
