Use only for an explicitly requested hosted destination, including one already
established in this conversation. Preserve the requested format and destination.

Find the installed upstream skill at
~/.config/agents/skills/synced/*/docs/SKILL.md and read it before the
first connector call. If more than one matches, ask which account's skill to use.
If none exists, report that the synced skill is unavailable; do not install one
or substitute a hosted destination.
