Tool call
The specific mechanism by which an agent's internal decision becomes a real-world action: a call to a tool, database, email service, payment processor, another system, that executes the action the agent decided on. The tool call is the exact point where an output-shaped decision crosses into action-shaped consequence, and it is the natural place to insert a checkpoint. A single user-visible action can be built from several chained tool calls, some running immediately and some queued for later; the checkpoint question has to be asked of the specific call that actually produces the consequence, not just of the first call in the chain.
Defined in 2 GAGE programs, which carry 2 distinct definitions of it. The wording above is taught in Agentic AI Governance: Applied Mastery.
How each discipline defines it
The same term does different work depending on who is using it. These are the definitions as each program teaches them, unedited.

The concrete action an agent takes by invoking a tool (a payment system, an email service, a database write), recorded with which tool, which parameters, and what result came back. The tool call is the ground truth of what the agent actually did, as opposed to what it said it would do.
