yohey-w/multi-agent-shogun is a shell project that runs multiple coding agent command-line tools in parallel inside tmux. It uses a hierarchy in which a top-level coordinator splits up the work and subordinate agents report back their results. The repository's latest release is v5.1.0, but the provided record does not state what changed in that version.
This structure does more than simply run agents at the same time: it focuses on delegating work while passing instructions and reports back and forth. The README lists Claude Code, Codex, Copilot, Kimi Code, OpenCode, Cursor, and Antigravity as supported tools, and explains that YAML files are used for task instructions and reports. The project is released under the MIT license. It also introduces a follow-up project, kagemusha, which shifts focus away from increasing the number of agents and toward a decision procedure that accumulates fixes as principles and standing rules.
Installation requires tmux, Bash 4 or later, and one of the supported tools. It is therefore a project centered on the layers and workflows that connect multiple agents, and it demands the necessary terminal environment. The specific changes in v5.1.0 cannot be confirmed from this record alone, so there is not enough information to evaluate improvements release by release.
