Check for Updates

This is a read-only update checker. It identifies the installation that supplied this skill, compares its version with the repository's main branch, and shows the update path supported by the current agent host. It never updates automatically.

Cadence

Keep these two controls separate:

• Invocation guard: Other Fabric skills invoke this skill once per session before continuing.
• Network guard: Automatic invocations perform a remote lookup at most once every 7 days for each detected installation identity.
