Agent Deck is an open-source agent harness and terminal-based fleet orchestrator created by Ashesh Goplani. Implemented in Go, it provides session lifecycle management, sub-agent orchestration, and persistent execution tracking for developer agent workflows. In daily use, Agent Deck operates as a CLI tool that launches and monitors agent sessions—such as Claude-based coding agents and autonomous task workers. It organizes concurrent runs by working directory or Git worktree group, tracking execution progress through completion ledgers, crash-safe message inboxes, and sentinel tokens to notify parent processes when tasks conclude. Agent Deck differentiates itself from basic agent wrappers by focusing on fleet fan-out and distributed execution. Rather than running one isolated prompt session, it lets parent agents launch independent child sessions, manage multi-worktree parallel tasks, wake parent tasks on child completion, and synchronize completion statuses across local and remote environments. Agent Deck is open source on GitHub and developed as a native Go binary with active tooling and continuous integration gates.
