A kanban board for when one AI agent isn't enough

What it does

agtx is a Rust TUI for managing AI coding agents. It spawns each task in an isolated git worktree and tmux window, letting you run Claude, Codex, Gemini, Cursor, OpenCode, or Copilot side-by-side on different jobs. A built-in kanban board tracks tasks through planning, running, and review phases, with the agent’s full conversation history preserved across the entire lifecycle.

The interesting bit

The /agtx:brainstorm and /agtx:sweep skills let you capture ideas mid-conversation without leaving your agent session—explore freely, then push the outcomes to the board as tasks in one step. If you enable the experimental orchestrator, an AI agent manages the board via MCP, delegating work and checking for merge conflicts while you focus on merging the results.

Key highlights

• Each task lives in its own git worktree and tmux session, so agents run truly in parallel without polluting your working tree
• Configure different agents per workflow phase—e.g., Gemini for research, Claude for implementation, Codex for review—with automatic session switching
• Auto-detects merge conflicts against the base branch using git merge-tree and dispatches a resolution skill when a review task goes idle
• Supports spec-driven workflow plugins like GSD, Spec-kit, OpenSpec, BMAD, and Superpowers, or use the void plugin for full human control
• Brainstorm and Sweep skills pipe agent conversations directly into the task board via MCP, no copy-pasting required

Caveats

• The orchestrator agent is explicitly marked experimental, so fully autonomous delegation is still a work in progress
• Requires tmux and is designed around git repositories; the GitHub CLI is optional but needed for PR operations

Verdict

Try this if you are already juggling multiple AI agent sessions and want a structured way to parallelize them without losing context. Skip it if you prefer a single agent in one terminal and find git worktrees overkill for your workflow.
