Hermes Deck

What Hermes Deck does

Hermes Deck is a SwiftUI app for macOS 14 or later that talks to a locally installed Hermes agent over a JSON-RPC TUI gateway on stdio. In the chat you can @mention another agent to route a message inline: @codex uses Codex over the Agent Client Protocol, @claude uses the Claude CLI, @gemini calls agy in single-shot print mode, and any Hermes profile can be addressed by name.

Agents can hand work to one another through a built-in deck_delegate_agent Hermes tool, with a fenced AgentRouting block as the fallback. The Deck forwards the request, feeds the reply back and shows a live status card under the triggering message. A right-hand sidebar holds a Kanban board, scheduled cron jobs, per-agent panels and settings. Past Hermes sessions are read from the backend SQLite database and can be reopened, installed Hermes tools and skills can be toggled, and dictation uses SFSpeechRecognizer.

Key features

• @mention routing to Codex, Claude, Gemini or any Hermes profile
• Agent-to-agent delegation through the deck_delegate_agent tool
• Switching between Hermes profiles such as default, coding and research
• Session history read from the Hermes SQLite database
• Kanban board and scheduled cron job panels
• Voice dictation with a selectable recognition language

When to use it

• Driving Hermes, Codex and Claude from a single macOS chat window
• Browsing and reopening past Hermes sessions
• Switching between Hermes profiles for coding and research work

Who it is for: Mac users who run Hermes and want a native chat app that can also reach other coding agents.

How it fits with Hermes Agent

It is a client for a local Hermes agent backend installed at ~/.hermes/hermes-agent, and it adds a deck_delegate_agent tool to Hermes.

Requirements: macOS 14.0 or later, a Hermes agent backend at ~/.hermes/hermes-agent, sqlite3 at /usr/bin/sqlite3; for external agents, Node/npx, the Claude CLI and agy on PATH as needed
