WHY AGENTS ARE SOON ONLY GOING TO HAVE 1 TOOL

Summary from the TLDR newsletter

Agents are collapsing their entire tool catalog into one 'exec' tool. This allows models to write short scripts that chain, combine, and await actions inside isolated sandboxes. Models can now reliably combine and chain dependent actions in a single pass. In the previous standard tool-calling model, agents could only perform single actions, but the exec tool allows them to perform multiple actions.
