Module tool_call 

Collapsible tool-call cards and the group that folds a burst of them.

A ToolCall shows one invocation: its name, a one-line summary, the shared status vocabulary, and — when expanded — the input the agent sent, the output it received, or the failure reason. Calls that need a human decision carry Allow / Deny controls. A ToolGroup collapses several consecutive calls behind one shimmering “Running N tools…” header so a transcript stays readable while an agent works.

Both are controlled: the application owns every invocation as a Progressive<ToolInvocation> and decides what each typed event means.
