ConPTY has no foreground process group, so the Unix process-table poll (pgid -> argv) has no Windows equivalent and foreground_agent was a stub returning None. Follow Warp's approach instead: the shell integration captures the submitted command line at preexec and carries it percent-encoded on the OSC 133;C mark; the daemon detects the agent from that string. - shell_integration: all four bodies (zsh/bash/fish/PowerShell) append the submitted line to 133;C, truncated to 512 chars and escaped (% ESC BEL CR NL). PowerShell guards the surrogate-splitting truncation and wraps the emission in try/catch (EscapeDataString throws on lone surrogates under .NET Framework / PS 5.1). - pane: ShellState.command stores the capture (cleared on D only, so a stray foreign A/B mid-command can't wipe the chip); on Windows apply_signals feeds it through the new detect_from_command_with. - cli_agent: detect_from_command_with tokenizes a typed command line (quotes, & call operator, case-insensitive) and reuses the argv detection; base_stem handles backslash paths and .exe/.cmd/.bat/.ps1. - ForegroundProbes::agent is now Option<Option<CLIAgent>>: None means 'no process-table view' (native SSH, Windows) and is never applied, fixing the 0.5s poll wiping event-branded agents on native-SSH panes.
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
