The toolset call start event, carrying the tool's configured parameters

asgard.tool_call.start

asgard.tool_call.start marks the start of a toolset call within a process. The toolCallStart object in fact lists the toolset's configured parameters, which matter both for debugging and for building a custom UI.

info

This event appears only when a toolset is in use.

Characteristics​

  • When it fires: as the process begins using a toolset
  • What it does: shows which toolset the process is using and with what parameters
  • How often: once per toolset call
