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.

Reference / Environment variables

CLAUDE_CODE_DISABLE_MEMORY_RO_UNSAVED_NOTICE

A Claude Code environment variable, read out of the shipped bundle. It has been in the build since v2.1.242, including the newest one read.

What it is

Writes into read-only memory stores now warn they were saved locally only and will be overwritten.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.242.

Presence across releases

ReleasesReadingDeclared typeDefault
2.1.245 – 2.1.250 5 releases never mined — —
2.1.242 – 2.1.243 2 releases in the build bool —

A row reading never mined is a release with no archived bundle behind it. Nothing was read out of it, so nothing here says whether the name was in it. A declared type or a default is only ever what that release's own bundle stated.

Changelog entries naming it

None of Anthropic's documentation pages this site has a copy of carries this name.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the environment variable does. All environment variables.
