hrack — harness rack

The modern terminal for coding agents.

The native TUI stays untouched. Who’s thinking, who’s calling tools, who’s waiting on you — at a glance. HRack watches every light, so you can look away and land back in the right place.

HRack

states

One status language for every agent

Hooks, SSE streams, and extension events from every harness are converged into one shared vocabulary. It does not matter which CLI is underneath — you only need to read six lamps.

working

working

Thinking, calling tools, running commands — everything on track.

needs-you

needs you

An approval or a question: it is waiting on you. Do not let it wait alone.

done

done

Turn complete, ready whenever you are.

error

error

A failure or non-zero exit. Worth a look.

idle

idle

Session open, nothing observed yet.

exited

exited

Terminal ended; the record stays on the rack.

flow

Observe from the side. Intrude never.

Events never enter the terminal byte stream, and the terminal never depends on the event stream. Two paths, one rack — either side can fail without touching the other.

  1. 01

    Run

    The CLI lives in a PTY. Its native TUI is not touched, byte for byte.

  2. 02

    Observe

    One adapter per harness translates official events into the shared vocabulary.

  3. 03

    Alert

    Status flows to the sidebar, floating window, and history — the lamp finds you.

If an observer fails, the PTY keeps running: the status degrades, the session does not.
