l0ng-ai 8ee9474045 fix(daemon): leave the ring the modes it still carries
`replay_state` sends the mode fold ahead of the ring so the replayed
frames land in the buffer they were drawn for, and it sent every mode
that was on — including the ones the ring itself still switches on.
`?1049h` is a no-op in the emulator once the mode is already set, so the
ring's own copy then stopped clearing the alternate screen: everything
the ring holds *ahead* of that sequence, which is the shell scrollback
the user had behind the program, was painted into the alternate buffer
instead. That buffer keeps no history, so those lines were thrown away,
and the primary buffer the program's exit returns the client to was left
empty. Reconnecting a minute after opening `vim` is the ordinary case,
and it lost the prompt the user left behind.

Only the modes a replay of the ring cannot speak for go ahead of it now,
and they are read from a fold over the bytes the ring actually still
holds — so a sequence the front cut in half counts as lost, exactly as
it will for the emulator that reads the same bytes.

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
