A router skill routes requests among a family of child skills by checking a stable inventory and providing explicit install-or-fallback guidance when the optimal child is unavailable. This keeps skill families discoverable under a single parent.

A router skill is a dedicated entrypoint that selects the best-fit child from a family of related skills. You need one when a software package requires an entrypoint that routes requests to nested child skills while surfacing explicit install-or-fallback behavior.

Setting up explicit handoff involves enforcing routing decisions across siblings using allowed relationships like routes_to and includes. The router evaluates these relationships to choose and reveal the best-fit child to the agent for explicit skill selection.

Yes, you can keep leaf skills inside the router package while supporting lazy loading of full child bodies. A nested child inventory in references/children.json maintains the stable family boundary required for this deferred loading behavior.

Yes, the router skill supports install hints by documenting them in install_if_missing. When the optimal child is unavailable, the router surfaces these explicit install-or-fallback policies to guide the agent on resolving the missing dependency.
