New in 3.4Learn vim's moves in the hjkl dōjō, and sleep a single agent

More agents.
Less babysitting.

Every agent gets a readable pane, the one waiting on you comes first, and idle Claude Code sessions recycle on the same conversation so your machine lasts weeks.

Install kansō Star on GitHub

Free and open source. A layout for Herdr on macOS.

kansō in Herdr: a projects sidebar with agents grouped by repository, three agents side by side on the strip, one of them waiting for a decision, and a status bar that says 2 agents need you.

Installed in one sentence

No config files to write. Your agent does it, and kansō tells you when an update is ready.

1
Tell your agent

Paste this into Claude Code, Codex or any agent running in Herdr.

add herdr.dev/layouts/jlopezlira/herdr-kanso--kanso
2
Herdr switches layouts

Your terminals and agents keep running. The sidebar, the strip and the panels appear around them.
3
Let them all run

Open as many agents as you like. Turn on the guard in Memory once, and kansō keeps long sessions light.

Everything around your agents, one key away

Panels open beside the strip and only work while you look at them.

A strip, not a grid

Each terminal keeps its width. New panes open beside the one you are in and the view glides to it. Nothing gets squeezed.

Four agents side by side in the middle of a row of seven, with rails at both edges for the panes beyond the screen.

Memory

Every agent's size and history. Recycle or close the idle ones from the panel.

Ports

Dev servers your agents started, which pane runs each one, and the ones left behind.

Spend

What your AI work is worth at list price, per project, model and task.

Worktrees

Every worktree agents made, what removing it would lose, and the disk it gives back.

Put agents to sleep, wake them where they were

Waiting on a backend ticket? Sleep the agents that wait on it. They exit with their conversation kept, so nothing of them runs or holds memory, and wake tomorrow on the same conversation.

One agent, a tab or a projectThe moon in a pane's header sleeps that agent and leaves the rest of the tab; the project's menu sleeps a tab or all of it.
The same conversationWake brings each agent back on its conversation, in its tab, with its folder and options, and checks it is really there.
Careful with your workA draft in the prompt is cleared, never sent. An agent at work or waiting on you doesn't sleep.

Keys you can see, moves you can learn

⌘⌥ h j k l move between panes as vim does, and every list answers j, k, gg and G. ⌘? draws your own keys on a keyboard, layer by modifier.

The hjkl dōjō: Hachi the pixel shiba, nine levels, a board with a target to reach with h and l.

kansō help

Hold ⌘ ⌥ ⇧ ⌃, or press a chord, and the keys that do something light up with what they do. A guide to everything, and where to set it up.

hjkl dōjō

Nine levels, from h and l on a board to w b e, f t and gg G on real lines of code. Rounds of ten targets, points for the fewest moves, a hint when you stop to think, and Hachi cheering a streak.

Agent sessions that last weeks

Agents that stay open for weeks grow. kansō's guard checks every minute and cleans up without losing a conversation.

Recycles bloated agentsA Claude agent idle for 20 minutes and past 900 MB exits and comes back on the same conversation, in a fresh process.
Never under your handsNot the agent you are on, not while you type, never one that is working.
Names what holds the memoryWhen the machine runs low you get a notice with the heaviest processes.
