hermes-bus-plugin 0.1.0

Hermes bus integration plugin — auto-start, auto-register, message injection, bus tools

hermes-bus-plugin

English | 中文

Hermes Agent plugin for message bus integration — lifecycle management, external message injection, bus tools.

A thin integration layer between Hermes Agent and the hermes-bus / hermes-notify packages.

Install

# Via Hermes plugin manager
hermes plugins install hermes-bus-plugin

# Or copy to ~/.hermes/hermes-agent/plugins/
cp -r hermes-bus-plugin ~/.hermes/hermes-agent/plugins/
hermes plugins enable hermes-bus-plugin

Session Naming

Each CLI window registers a unique bus endpoint on startup. The default endpoint is hermes-bus (first session), with hermes-bus-2, hermes-bus-3, etc. for additional sessions. To give your session a stable name that survives reconnection:

/title my-agent-name

The plugin uses the title set by /title as the bus endpoint name.

Action	When	Description
Start bus daemon	Plugin load	Ensures hermes-bus is running
Register listener	Plugin load	Opens a bus endpoint for incoming messages
Inject context	pre_llm_call	Queued bus messages are injected into LLM context

Provided Tools

bus_send — send a message through the bus to any endpoint:

bus_send(target="notifier", type="progress", text="50% done")

bus_status — check bus health and connected endpoints:

bus_status()

bus_info — show current session's bus connection details:

bus_info()

Requirements

• hermes-bus (pip)
• hermes-notify (pip)

Both are auto-detected — the plugin degrades gracefully if they're missing.

Architecture

External process ──→ hermes-bus ──→ hermes-bus-plugin ──→ LLM context
                        (socket)        (pre_llm_call hook)
                        
Hermes session ──→ bus_send tool ──→ hermes-bus ──→ target endpoint
