Codegrid is an agent skill from BankrBot/skills. CodeGrid is a native macOS canvas where multiple coding agents (Claude, Codex, Gemini, Cursor, Grok, shells) run side by side in panes and collaborate via a local agent bus — no tmux, no cloud, no account, no stored API keys. Install this skill when an agent should know how to operate inside a CodeGrid pane, drive the workspace from outside (control socket or codegrid:// deep links), spawn or message sibling agents, or coordinate multi-agent work (delegate, review, pipeline, parallel fan-out, monitor, debate)…
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `catalog.json`, `references/codegrid-agent-bus.md` and `references/using-codegrid.md`).
It sits in Agent Workflows, covering Multi-agent orchestration. It works with tmux and macOS. The repository describes itself as: Bankr Skills equip builders with plug-and-play tools to build more powerful agents.
