SeaShell

SeaShell 0.2.0

Terminal window manager for running several long-lived sessions — agents, dev
servers, plain shells — side by side, with a file explorer that knows what your
panes are talking about.

File Platform Notes
SeaShell-0.2.0-universal.dmg macOS 11+ (Intel & Apple Silicon) unsigned — see below
SeaShell-0.2.0-windows-x64.zip Windows 10/11 x64 experimental — see below
SeaShell-0.2.0-linux-x86_64.AppImage Linux x64 experimental — built in CI, not yet run on real hardware

What's new: Lookout

SeaShell now notices when an agent pane stops to ask you something and raises an
approval card in the corner — the question, plus buttons that answer that
pane without leaving the one you're in.

  • Works out of the box on every platform: when a claude pane goes idle on a
    question, a card appears with Continue / Yes / No / Go to pane.
  • Smart drafted replies come from the companion plugin:
    /plugin marketplace add voidharbor/claude-plugins then
    /plugin install c-assistant@voidharbor. With it installed, cards arrive with
    a one-line reply drafted in your own voice — approve it, edit it, or deny it.
    (The voidharbor bundle plugin carries the commands but not the Lookout
    hooks, so smart cards need the standalone c-assistant install. macOS/Linux.)
  • The safety model in one sentence: external tools can only propose a card —
    the only thing that ever submits into a session is your own click, re-checked
    at click time against a moved-on or picker-showing pane.
  • Toggle it in Settings ("Approval cards"); the status-bar 🔭 badge counts
    what's waiting.

Installing on macOS

The app is not yet signed with an Apple Developer ID, so Gatekeeper refuses a plain
double-click the first time.

  1. Open the .dmg, drag SeaShell to Applications.
  2. Right-click → Open → Open once (or System Settings → Privacy & Security →
    "Open Anyway").

Installing on Linux (experimental)

chmod +x SeaShell-*.AppImage && ./SeaShell-*.AppImage

Panes root at your $SHELL, falling back to bash. Live working-directory tracking
(and double-click path reveal for relative paths) needs zsh. Unit-tested in CI;
reports from real machines welcome.

Installing on Windows (experimental)

Unzip anywhere, run SeaShell.exe. SmartScreen warns on unsigned apps — "More
info → Run anyway". Lookout's detector cards work on Windows; the smart-draft
plugin lane is macOS/Linux for now.

Known limitations

  • All builds unsigned — expect the OS warnings above
  • No session persistence across restarts (saved Projects are layouts, by design)
  • Linux and Windows are experimental; macOS is the reference platform
  • Cards for picker/selection screens are deliberately look-only — answer those
    in the pane itself
