Hook installation was written for one machine — this one — and a remote workspace runs its agents on the far side of the connection, where none of that is true: a different `$HOME`, a different filesystem separator, and a `tty7` binary at a path this client published rather than the one it is running from. `HookTarget` is that machine, borrowed for the length of one background task: `local` resolves our own home and binary, `remote` takes the home a handshake reported and the `tty7-server-<version>` this client installed there. Every path the installer builds now goes through it, via `Host::join` rather than `PathBuf::join` — a Windows client installing onto a Linux box was writing `/home/me\.claude`. The three things that are only true locally (our own environment variables, atomic writes, running the `codex` CLI) are gated on `is_local` instead of assumed. Settings grows a machine picker so the page states which one it is acting on. Also in this commit, three unrelated UI fixes: - The settings sidebar's search placeholder sat 6px right of every nav label under it — a `small` (14px) magnifier where the rows use 16, a 4px gap where they use 8, and an `Input` that adds `input_px` (12px at the default size) whether or not it draws a box. All three corrected, so the placeholder starts on the rows' 32px text column. - The "'X' is still running — reopen it from the workspace menu" toast is gone, along with the `workspace_detach_hint_seen` flag that existed only to show it once. Detaching a workspace is what ⌘W has always done here and the Window menu already lists what came off screen; a one-time lecture on top of that is noise. Old configs carrying the key still load — `Config` doesn't deny unknown fields.
tty7
A terminal workbench: shells, sessions, SSH, coding agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
Why
- Fast — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Sessions persist — quit or reboot; your shells keep running, no tmux
- Editor-grade input — completion, syntax highlighting, history search built in; zero config for zsh, bash, fish, PowerShell
- Agent-aware — recognizes Claude Code & co. in a pane: status, notifications, session resume
