# Astryx Chat Tool Calls

> ChatToolCalls displays tool or function call invocations from an LLM response. Pass an array of calls and the component handles the rest: a single call renders inline, while multiple calls collapse into a summary with the latest call visible at the surface. Use it anywhere an AI agent shows what actions it took.
