What
When a long conversation is compacted, meaning summarised to free up room, Claude Code adds a note about tool results that were too large to include. That note now covers only those oversized results. The sentences about tool calls that were refused or stopped are gone, and the advice now reads: "Repeat a left-out call only if it just reads, for only the part you need, a few at a time."
Why
Claude gets less guidance after a summary about calls that were refused or stopped.
