Definition — An AI Tool is a specific action an AI assistant or agent can call to get something done, such as searching a directory, looking up a record, running a calculation, booking a time, or opening a ticket. In Halley AI™, each tool is scoped to the data and actions your workflow allows.
The specific actions an AI Agent can take, such as a search, a lookup, or a booking, so it can act, not just answer.
A tool gives the model a defined way to act. The model decides when a question needs a tool, calls it with the right inputs, and uses the result in its answer. Without tools, an assistant can only answer from what it already knows. With them, it can check a record, run a search, or start a process.
Tools are what turn an assistant from something that answers questions into something that finishes the job. For the American Gem Trade Association, Halley's assistant calls a directory search tool that handles misspellings and synonyms, so members find the right supplier without knowing its exact name.
