agtx is a terminal-native agentic development environment that runs eight coding CLIs as specialists around one shared blackboard: tasks on a kanban, each executed by an agent in its own git worktree and tmux window.

**The bet is the blackboard architecture from AI research: specialists that never see each other's context, exchanging only what lands on the board.**

## What it is

A Rust TUI installed by script or built with cargo, driving Claude Code, Codex, Cursor, Grok, OpenCode, Gemini CLI, and more (eight CLIs) against a task lifecycle of backlog, planning, running, review, and done with a dependency graph.
Each phase can run a different agent with automatic switching and context handover, e.g. Grok researching, Claude implementing, Codex reviewing, with the conversation history persisted across the phases.
When a review task goes idle, agtx checks merge conflicts against the default branch with a non-destructive virtual merge (`git merge-tree`) and hands the agent its own `/agtx:merge-conflicts` skill to resolve and re-commit.
A QR-paired installable web app puts the board, task details, diffs, and the live terminal (keyboard included, for permission prompts) on your phone over Wi-Fi or a Tailscale tailnet, and an `/agtx:oneshot` skill runs the whole board unattended, planning milestone waves, unblocking workers, judging review, and merging.

## Strengths

- **One worktree and tmux window per task, with agent-driven conflict resolution, is workflow depth most board tools fake with a checkbox.**
- The per-phase agent assignment (research, implement, review) makes multi-model collaboration concrete instead of aspirational.
- The oneshot skill turns the board into an unattended runner with merge judgment, a full loop rather than a launcher.

## Cautions

- The release train stopped at v1.0.6 in mid-September 2026 and the last push is nine days old at this writing, so momentum is worth watching before you depend on it.
- Solo-maintained, with no third-party reviews or benchmarks found.
- The mobile web app needs the same network or a tailnet, so it is a companion, not a hosted control plane.

## Pricing

Free and open source under Apache-2.0.
No paid tier, account, or hosted service as of 2026-11-01.

## Compared to

- [dmux](../dmux/index.md): the tmux TUI pairing one task pane with one worktree; agtx adds the phase lifecycle and cross-model handover.
- [LoopTroop](../looptroop/index.md): the local GUI orchestrator with council planning over OpenCode; agtx stays terminal-native and drives eight CLIs.
- [Vibe Kanban](../vibe-kanban/index.md): the board-first web app; agtx is the terminal counterpart with per-task worktrees as the core mechanism.

## Bottom line

**Recommended for terminal people who want per-task worktree parallelism with different models owning different phases of one task.**
Not for GUI-first users, and not for remote or VPS workflows, which it does not target.

## Changes

- 2026-11-01 - Created.
