l0ng-ai cd1353fd98 fix(ssh): stop the password prompt coming back after a reconnect (#820)
Three things had to line up for a password sheet that keeps reappearing
after the connection has already succeeded, and cannot be closed. Two of
them are here; the third was the reason closing it never helped.

The connection cache keys one slot per host, and that slot's mutex is
what makes a reconnect ask for a password once rather than once per pane
— everyone dialling the same host queues on it, and all but the first
find the connection the winner left behind. Eviction removed the map
entry outright. A dropped TCP connection kills every pane riding it at
the same instant, so all of them reach the dead-reuse branch in
`run_session` together: the first removed the entry, its `open_connection`
inserted a fresh mutex, and the pane a moment behind it removed *that*
one — the mutex a handshake was already holding — and inserted another.
Each pane ended up alone on a mutex of its own, ran its own handshake and
raised its own prompt. Answer one and the link comes up; the rest are
still queued behind it. Eviction now empties the slot instead of
replacing it, and leaves a slot somebody is dialling on completely alone.
The entry outliving its connection is what the map already looked like
everywhere else, and `routes()` has always reported such a slot as
disconnected rather than omitting it.

The second is what happened on close. A declined prompt failed only the
method that raised it, and `authenticate` walked on to the next one — but
`password` and `keyboard-interactive` are one question asked two ways, and
a server offering both wants the same secret either way. Closing the
password sheet put a keyboard-interactive sheet up asking for the same
password. Nobody declines a *method*, so a declined prompt now ends the
attempt, with a reason distinct enough for a caller to recognise.

That caller is the workspace supervisor, which reconnects on a clock and
treated the refusal as a transient failure: it dialled again a second
later, and every thirty seconds after that, for the rest of the session.
It now suspends the machine instead. The strip already says why and
offers Retry, which is the user asking to be asked again.

A key passphrase is left alone deliberately. Closing that sheet declines
one key, and the methods still to come ask a different question — someone
who cannot remember a passphrase is usually closing it precisely to be
asked for a password instead. So is the fact that a password is only kept
across reconnects when "Remember" was ticked: that is a choice about
storing a secret, not a bug.

tty7 with a tab sidebar of agent sessions across several repos, running Claude Code

Why

A background server owns your shells and panes — not the window. Everything below follows from that.

  • Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
  • Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
  • Agent-aware — Claude Code, Codex & co.: status, notifications, and git context for every repo at once
  • Scriptable by agents — one agent opens a pane for another, hands off a task, waits, and reads the result, with or without the GUI running
  • Editor-grade input — suggestions, completion, highlighting, history search, with no plugin to install
  • Remote development — files, repos, panes, and git data stay on the remote machine, over a native SSH stack
  • Git beside the terminal — source control, diffs, and worktrees without leaving the window

Install

Native builds for macOS, Windows, and Linux on Releases:

macOS …-macos-arm64.dmg · …-x86_64.dmg drag into Applications
Windows …-setup.exe · portable ….zip
Linux …-x86_64.AppImage chmod +x and run — X11/Wayland libraries bundled

What's inside

Agent-aware per-pane detection (20 CLIs) · status dot · notifications · branch + diff · tray icon when input is needed · resume after reboot · tab sidebar grouped by repository
CLI + Skills bundled tty7 CLI · agent skill · run streams a command and exits with its code · split · send · wait --until free · capture
Editor-grade input ghost suggestions from history · explained tab completion · syntax highlighting · multi-line editing · click places the caret · ⌃ R fuzzy history
Window tabs & splits · ⌘ P palette · ⌘ F scrollback search · ⌘ J panel with process tree and listening ports · 13 themes, your own YAML, iTerm2 import · IME
Shell integration injected when a pane starts, nothing to install · prompt marks · working directory · exit codes · command-finished notifications · zsh, bash, fish, PowerShell, WSL, remote panes
Remote workspaces remote files, repos, changes, diffs, worktrees, tabs, and panes · reconnect from any client and continue where you left off
SSH native russh stack: profiles with keychain secrets · SFTP panel · port forwarding · jump hosts · one-time, unprivileged tty7-server install
Git panel follows the focused pane · stage, commit, amend, branch, push, stash · side-by-side or unified diffs · commit graph with cherry-pick, revert, and reset · a new worktree opens its own tab

Supported agents

Detection is free: brand avatar, branch + diff, tab title. Status takes one click under Settings → Agents to install that agent's hook, and brings the status dot, notifications, the tray icon, tty7 wait, and resume after a reboot. Fork needs both — the agent's own fork command, and the hook that tells tty7 which session to fork.

None of them are wrapped or proxied — the agent you start is the agent you get, in a normal PTY, with its own interface. An agent launched through a wrapper script can be mapped to one by name with agent_commands in config.json.

Documentation

Full documentation lives in docs/keyboard shortcuts · config.json · CLI reference. The agent-facing CLI interface is also documented in skills/tty7/SKILL.md.

Install the skill with:

npx skills add l0ng-ai/tty7    # install
npx skills update tty7         # update later
