A new ui::lsp module runs language servers for local files the editor opens: rust-analyzer, typescript-language-server, pyright (or pylsp), gopls and clangd, from a registry table. Each server is keyed by (server, project root), found from markers such as a Cargo workspace, package.json, go.work/go.mod or pyproject.toml, and shared by every buffer under that root. A server missing from PATH (which tty7 already fills from the login shell) means no LSP for that language and a one-line hint in the status bar. The JSON-RPC client frames Content-Length messages over the server's stdio on dedicated threads, holds everything back until initialize is answered, cancels requests nobody waits for any more, and answers the server's own requests (configuration, capability registration, applyEdit). Documents use full-text sync, debounced, and flushed before every request. A server whose last file closed shuts down after a grace period, every server exits with the app, and one that crashes is restarted a few times before it is left down. Features: diagnostics as underlines with hover messages and an error and warning count in the status bar; completion (snippets flattened to plain text); hover; go to definition by secondary-click or F12, across files through open_file_in_editor_at; code actions on the editor's own menu (cmd-.), resolved and executed as the server needs; Format Document (shift-alt-f); and Rename Symbol (F2) in the editor's bar, applied to open buffers and to files on disk. The key bindings sit in the Input context so F2 and F12 stay with terminal programs. Positions are converted at the boundary: servers count UTF-16 units, gpui-component counts chars, and the rope counts bytes. The new editor_lsp setting (default on) turns it all off.
tty7
A terminal workbench: persistent sessions, remote work, agents.

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

Supported agents
Detection is free: brand avatar, branch + diff, tab title.
Status takes one click under Settings → Integrations 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.
Every agent on your PATH is also a row in Search Everywhere (Agent: Claude Code, …)
that opens it in a new tab, and the New Tab menu names the ones you have actually
run. agent_launch sets the command line it starts with.
