What
A tool call is a single action Claude takes, such as running a command or reading a file. When a tool call's output is too large and Claude Code cannot save the full output, Claude receives a message about it. That message has been reworded. It now says:
the output was too large and could not be saved, so only the first part is shown and the rest was dropped
when several calls in one reply overflow, those results share one limit
Claude can page through the output, filter it, or repeat the call with fewer calls per reply
Why
Claude gets clearer guidance when part of a tool's output is lost, so it can try a better way to get what it needs instead of working from incomplete results.
