tool call · capacité d’action
Tool
A callable operation that lets an agent observe or change a system through an input and output contract.
Key difference
A tool provides a capability; a skill explains when and how to use it in a procedure.
Example
A function reads a file and returns its content with an explicit error status.
Counter-example
A review checklist is not an executable tool; it may be part of a skill.
