What's wrong with this entry?
When a tool result or file listing is too long for the context window and must be truncated, the cutoff now shows:
... and 42 more (truncated for prompt size)
Previously the list was silently cut with no indication of how much was omitted.
Truncation notice (search for "more (truncated for prompt size)")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
