l0ng-aiandl0ng-ai cd9577c590 feat(agents): recognize CLI coding agents + git branch in the sidebar (#85 )

* feat(agents): recognize CLI coding agents + show git branch in the sidebar

Observe (never wrap) third-party coding agents running in a pane — Claude
Code, Codex, Gemini CLI, Aider, Amp, OpenCode and ~10 more — and enrich the
UI around them, plus front each sidebar row with its git branch and diff.

Detection & identity
- Command-based detection over the foreground argv (launcher basename, and
  interpreter-wrapped `node …/cli.js` / `npx …` forms), with user rules via
  `agent_commands` in config. Brand avatars on the tab chip and sidebar row.

Rich status channel
- A per-pane state machine (idle / working / waiting-for-you / done) driven
  by agent-reported events over an OSC 777 sentinel channel
  (`tty7://cli-agent`, versioned JSON), sniffed daemon-side and streamed to
  the client (DaemonMsg::AgentStatus).
- `tty7 agent-hook claude <event>` + a palette installer wire Claude Code's
  lifecycle hooks up; the hook writes the sentinel to the controlling tty
  (with an ancestor-tty fallback for detached hook processes).
- Avatar status dot: working (blue) / waiting (amber) / done (green); an
  unread finished turn gets a crisp outer ring that clears on focus.

Notifications, resume, context feed
- "Needs your permission…" the moment an agent blocks; "finished after Ns"
  per turn, honoring the notify policy (rich turns suppress the coarse exit).
- Session resume: restored panes re-launch their conversation
  (`claude --resume …`), gated by `restore_agent_sessions` (default on).
- Palette commands send the current selection or the repo `git diff` to the
  running agent as a ready-made prompt.

Sidebar git line
- New `terminal::git_status`: off-thread `git` probe (branch, or short sha
  when detached; `git diff --numstat HEAD` line counts) with
  GIT_OPTIONAL_LOCKS=0, refreshed on cwd change or command finish, dropped
  on a stale cwd via a generation tag.
- Each row is avatar + title + `⎇ branch  +N −M` (green/red), sized to
  content; the redundant cwd/"Working…" lines and the aggregate rollup are
  gone — the status dot and branch line carry it.

672 tests pass.

* fix(agents): repair CI and refresh the git line when an agent turn ends

- The live PTY detection test used `sh -c 'exec -a codex cat'`, but
  `exec -a` is a bashism dash (Ubuntu's /bin/sh) rejects — spawn bash.
- cargo fmt over cli_agent.rs / view.rs / app.rs.
- An agent session is one long foreground command, so the back-to-prompt
  edge never refreshed the sidebar's branch/diff line while the agent
  worked — exactly when the working tree changes. poll_agent_status now
  reports a turn ending (transition into Done) and the poll reprobes git
  on that edge too.

tty7

A GPU-rendered terminal in pure Rust.

Why tty7

Fast — about 2× the throughput of Alacritty, Ghostty, or Kitty on the same hardware (benchmarks)
A modern prompt — completion, syntax highlighting, and history search built in; no plugins to assemble
Sessions that survive — close the window or quit the app, your shells keep running; no tmux
Zero config — zsh, bash, fish, and PowerShell work out of the box

Native builds for macOS, Windows, and Linux ship with every release.

Install

Download the build for your platform from Releases:

macOS — tty7-<version>-macos-arm64.dmg (Apple Silicon) or …-x86_64.dmg (Intel); open it and drag tty7.app into Applications.
Windows — …-windows-x86_64-setup.exe (installer: Start Menu shortcut + uninstall entry), or …-windows-x86_64.zip (portable: unzip and run tty7.exe).
Linux — …-linux-x86_64.AppImage (recommended: bundles the x11/wayland libraries, so it runs on Fedora / Arch / etc. with no extra packages — chmod +x and run), or …-linux-x86_64.tar.gz (bare binary; extract and run ./tty7, needs the usual x11/wayland runtime libraries installed).

Features

At the prompt

Ghost suggestions — your history completes the whole line as you type; → to accept
Tab completion that explains — every flag and subcommand with its description, for ~100 common commands
Syntax highlighting — as you type, nothing to install
Fuzzy history search — ⌃ R shows what you ran, where, and whether it failed
History from day one — your existing shell history just works, and carries across sessions
Real line editing — selection, word motion, undo

In the window

CLI coding agents

tty7 recognizes third-party coding agents running in a pane (Claude Code, Codex, Gemini CLI, Aider, Amp, OpenCode, and ~10 more) and enriches them — it never wraps or replaces the agent.

Brand avatars — the tab chip / sidebar row shows which agent runs where; custom wrappers map in via agent_commands in config.json
Live status dot — working (blue) / needs your input (amber) / done (green), driven by agent-reported events over an OSC channel; run Agent: Install Claude Code Hooks from the palette to wire Claude Code up
Notifications that matter — "needs your permission…" the moment an agent blocks on you, and "finished after Ns" per turn, honoring your notification policy
Branch at a glance — each sidebar row shows its pane's git branch and working-tree diff (+N −M), refreshed on cd and when a command finishes
Session resume — panes lost to a reboot re-launch their agent conversation (claude --resume …) on restore (restore_agent_sessions, on by default)
Context feed — palette commands send the current selection or the repo's git diff to the running agent as a ready-made prompt

SSH connection manager

A native Rust SSH stack (russh) is the only path — profiles, credentials, and SFTP without ever shelling out to ssh. There is no system-ssh compat mode.

QuickConnect — type user@host[:port] in the palette and connect; IPv6 [::1]:port supported
Saved profiles — full connection config with passwords / passphrases in the OS keychain, never on disk
~/.ssh/config aliases — type one to connect (resolved natively — common fields, best-effort — over russh), or import them as profiles in Settings
GUI auth — in-pane sheets for password, key passphrase, 2FA, and host-key confirmation (new vs. changed)
Built-in SFTP — a slide-in file panel: browse, upload / download, rename / delete / chmod, drag to Finder
Port forwarding — Local / Remote / Dynamic, preconfigured or added live, plus ⌘-click localhost:PORT to auto-forward
Jump hosts & proxies — multi-hop via profile references or ProxyJump, ProxyCommand, SOCKS5 / HTTP

Entry point	Connects via
Saved profiles · QuickConnect · typed `user@host[:port]`	Native russh — SFTP · keychain · GUI auth · L/R/D forwards
`~/.ssh/config` aliases	Resolved natively, then russh (`Match`/canonicalize/GSSAPI unsupported — no fallback)

Benchmarks

All four terminals measured back-to-back on the same machine, same day, same 155×40 grid — Apple M1 Pro, macOS 26.3.1, five-run averages (2026-07-04):

	tty7	Alacritty	Ghostty	Kitty
Plaintext IO — 11 MB `cat` _{(lower = better)}	95 ms	239 ms	179 ms	185 ms
DOOM-fire frame rate _{(higher = better)}	888 fps	485 fps	552 fps	617 fps
Cold-launch memory	116 MB¹	105 MB	128 MB	130 MB

_{¹ GUI 105 MB + the persistent daemon 11 MB.}

Where the speed comes from:

The PTY is read at device speed and parsed in large batches, off the render path
Hot paths are lock-free — a big cat never waits on drawing
The daemon buffers up to 16 MiB ahead of the window before backpressure applies

Methodology (how each terminal is driven, grid fairness, known pitfalls) and one-command reproduction live in scripts/bench/ — run it yourself.

Keybindings

Keys are shown in macOS notation — on Windows and Linux, read ⌘ as Ctrl. Open Settings with ⌘ , to browse or remap them all. The essentials:


`⌘ T` · `⌘ W` · `⌘ ⇧ T`	new tab · close tab · reopen closed tab
`⌘ 1`…`⌘ 9` · `⌃ ⇥` · `⌃ ⇧ ⇥`	jump to tab 1–9 · next tab · previous tab
`⌘ D` · `⌘ ⇧ D`	split right · split down
`⌘ ]` · `⌘ [`	next pane · previous pane
`⌘ ⌥ ←→↑↓`	focus the pane in that direction
`⌘ ⏎` · `⌘ ⇧ ⏎`	toggle fullscreen · maximize / restore the pane
`⌘ K`	clear the screen and scrollback
`⌘ P`	command palette
`⌘ F`	search the scrollback
`⌃ R`	fuzzy-search shell history
`⌘ +` · `⌘ −` · `⌘ 0`	font size up · down · reset

Settings → Keybindings lists every shortcut. Click one, press the new keys (Esc cancels, Backspace resets to default), and it takes effect immediately. Pane resize and swap have no default keys — bind them here or run them from the command palette. Prefer tmux muscle memory? Flip the tmux preset to remap pane/tab actions onto a prefix (default ⌃ B): ⌃ B C opens a tab, ⌃ B % splits, ⌃ B then an arrow moves focus. A bare prefix reaches the shell after a brief pause, and prefix + an unbound key is passed straight through to the terminal.
