BLOG ILLUSTRATION / EXECUTION STORY

From a tool call to a tool result

Two author-created traces inspect the hypothetical locale cache. A complete tool call executes. A cut-off tool call returns a failure result without executing. Select either trace in this full page.

A tool call runs only after the harness accepts it The harness runs an accepted tool call and returns a tool result tagged with its tool-call ID. A cut-off tool call takes a no-execution branch, which returns a failure result. Both tool results enter the next model call through a control-feedback path.
