Tool Use
Tool use is when an AI agent invokes external functions or services (like search, code execution, or databases) to complete tasks beyond pure text generation.
Plain-English meaning
Tool Use is used here to describe agent calls external actions. In the daily board, the word is grouped by the role it performs rather than by spelling or market popularity.
You may encounter it in a product interface, technical document, risk report, policy paper, or market dashboard. The term is included for recognition and comparison, not as a product recommendation.
Why it belongs with AI Agent Building
These terms explain how agents are composed, grounded, and protected against common attacks.
When solving the puzzle, compare the job this term performs with nearby cards. A correct group usually shares a function, risk type, workflow, or market structure rather than simply sharing similar wording.
Where you might see it
You might encounter this term while reading educational explainers, product documentation, risk disclosures, market dashboards, or beginner guides. Always separate vocabulary learning from financial decision-making.
