Show HN: Yaw – A terminal built around the Claude Code/Codex CLI workflow (opens in new tab)

The friction of "launch agent, need shell in same directory, open new tab, cd back — fifty times a day" is the kind of micro-friction that compounds significantly in practice. The auto-snap workflow that detects the agent CLI and splits the pane automatically is a clean solution to a genuine ergonomic problem.

What's interesting about the AI coding CLI workflow space is that the tooling is evolving much faster than the mental models for using it well. The terminal is becoming a coordination surface — not just for running commands, but for managing the relationship between human attention and agent execution.

The Agile Vibe Coding Manifesto's concern with "automation remaining verifiable" is partly a terminal/observability problem: when the agent is running in a pane you can see, its actions are visible and interruptible. When it's a background process with only a text log, the accountability relationship degrades.

Curious how the chat panel that sends terminal output as context to the AI compares to just having the agent run in a pane you can see — that seems like the interesting design tension here: https://agilevibecoding.org

The auto-snap detection is clever - automatically splitting when it detects an agent CLI is a great UX decision.

I took a similar "own the terminal" approach with Pane (https://runpane.com), but organized around git worktrees instead of splits. Each feature gets its own isolated worktree with N terminals, so agents never step on each other's files. The worktree lifecycle is fully automated.

Curious how you handle the case where someone is running 5+ agents on different features simultaneously? That's where the worktree isolation really shines vs. splits in a single repo checkout.

Creator here, happy to answer questions. A quick demo of the auto-snap workflow: you type 'claude' or 'codex' in any pane, Yaw detects it, and splits — agent on the left, shell in the same directory on the right. When the agent exits, the split closes automatically. It sounds trivial but it removed a surprising amount of friction for me.

Love to hear others pain points around terminals!

Love it! This terminal terminals like no other!
