Agent Builder

Routing

Use this skill after intent-recognition chooses an agent-anchored design, or when the conversation already targets an Agent and the user is continuing that build. Do not rerun intent recognition for routine Agent edits or extensions. Use build-agent only for Agent artifacts.

For a new Agent request, make the first build-agent call with a faithful copy of the request as soon as any required orchestrator-owned prerequisites are ready. Before that call, use ask-user only to choose a supported channel or to define a workflow or data-table prerequisite that the orchestrator must create. Only ask about the channel after list-agent-capabilities shows that the requested channel is unsupported. Do not collect model, service, tool, topic, schedule, credential, or other Agent implementation choices first. The embedded Agent Builder asks those questions through the build-agent call.
