Agent Monitor

A Silo extension that keeps track of every coding agent running in your terminals — so you always know which ones are working, which finished, and which are waiting on you — without tabbing through every terminal to check.

What you get

• Status rows in the Workspaces panel — each terminal running an agent gets a row while it's busy (with elapsed time) or once it finishes and needs your attention
• Terminal tab badges — a spinner, warning, or checkmark decorates the tab itself, so status is visible even with the panel closed
• Sticky "needs attention" — a finished/errored agent stays flagged until you actually view that terminal, so nothing gets missed in a stack of background sessions
• Survives restarts — per-terminal state (and elapsed time) is persisted, and a restored row is marked "(unconfirmed)" if the gap since last seen is long enough that the agent may have finished without being observed
• Configurable — a Settings page toggle to suppress status for whichever terminal is currently focused, instead of always showing it

Supported agents

Detection is driven entirely by terminal escape sequences (OSC), so there's nothing to configure per-agent:

A plain shell only gets a row once one of the agent-specific signals fires in it (e.g. typing claude into an ordinary terminal); it's demoted back to a plain shell once the agent process exits.

Permissions

None — the extension only reads terminal OSC output and workspace/terminal state, all exposed through the SDK without any capability grant.
