DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.247

Memory files are told to stay small and split rather than grow

Memory

Claude is now told to keep memory files small and split them rather than sprawl.

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.
