The Windows agent status dot (working/waiting/done) never showed because `write_to_controlling_tty` was a `false` stub on Windows — the hook's OSC 777 sentinel event was never injected into the pane's PTY, so the daemon never learned the agent's turn state. The hook has no `/dev/tty` on Windows, and agents (Claude Code, a Node app) spawn hooks with CREATE_NO_WINDOW, giving the hook its own *hidden* console — so a naive `CONOUT$` write succeeds into a dead-end buffer. Mirror the Unix "write the agent's tty" strategy at the console layer: walk up the parent chain to the shell tty7 spawned (the ancestor whose parent is the tty7.exe daemon — the process actually on the pane's ConPTY), FreeConsole off the hidden one, AttachConsole to the shell's, and write CONOUT$ there. The OSC bytes then flow through ConPTY to the daemon exactly like the shell-integration marks. Falls back to spraying every ancestor console when the shell can't be pinned down. Adds the windows-sys Win32_System_Console feature for Attach/FreeConsole. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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
