Know which agent needs you — on any host.
Pick one to see it.
Waiting turns amber
When Claude Code or Codex stops to ask, its pane turns amber — and so do its tab, its desk and its host, on every device you have. Answer it and the mark clears everywhere.
No hooks to install
Agents report their state with OSC 7501 — blocked, error, working, done, idle — and, when blocked, why: a permission, a question, a login. The keeper reads it off the screen, so nothing goes into an agent’s settings and every program is covered.
Watched with no window open
The keeper reads what runs in a kept shell even when no device is looking, so a session nobody has open still gets its mark — and its notification.
Resume the conversation
After a restart, Reopen starts the shell again in its folder and types the command that resumes Claude Code’s or Codex’s conversation at the prompt — claude --resume … — and Return runs it. The side panel’s Info shows the command too.
A desk per server and project
A desk is a workspace on one machine and folder. Tabs across the top switch desks; split panes side by side or stacked, each with its own tabs.
Pages the agent drives
A dev server’s port opens as a page beside its shell, reached through your SSH connection and exposed to nobody. Add SpectaShell to the agent once (Settings ▸ Agents: an MCP server the keeper runs) and an agent in a kept shell gets tools to open the page, read it as a tree of roles and names, click, type, fill, choose and scroll, run JavaScript, read its console and take screenshots, while you watch; Stop keeps agents off it.
