What
When a memory file (such as CLAUDE.md) or its index gets truncated for being too long, the warning message now states exactly which line the cut started at, and where possible, quotes the first roughly 80 characters of that line.
Why
Previously the warning only said a file was too long, without saying where. Naming the exact line and showing its content makes it much easier to find and fix the part of a memory file that's causing content to be dropped.
Names in the bundleCLAUDE.md
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Added since
A small documentation edit on How Claude Code works touched a line naming CLAUDE.md after this was published.
* `/init` generates a starter CLAUDE.md for your projecthow-claude-code-works see the edit
Confirmed since
Anthropic's documentation has since written up CLAUDE.md, on Claude Code changelog.
* Fixed the attribution reminder overriding a CLAUDE.md or memory rule against commit and pull request attribution; lines set by managed settings still applychangelog see the edit
