What
The prompts that teach Claude how to save memories now include a size rule: keep each memory file and its recall preview under a limit, and split or summarize a file instead of continuing it into a second one.
Details
The three memory system prompts stopped carrying their own copies of the how-to-save bullets and now call one shared builder taking {skipIndex, file}.
The new size guidance is appended to the index-based variant too, so all memory prompt shapes carry it.
Evidence
split or summarize it rather than continuing it in a second file.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
