What
A tool is an action Claude can take, such as reading a file or running a search. When a tool's result is too large to send back, the message about it has been reworded. It now says which tool ran, in the form " ran, but its result is too large to send back." It also suggests what to do next:
Ask for less of it. For a PDF, that means fewer pages at a time.
Narrow the search.
Check what the tool changed before running it again.
Why
Claude gets clear guidance for its next step when a result is too large, rather than just an error.
