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_ENABLE_STREAM_WATCHDOG

A Claude Code environment variable, read out of the shipped bundle. It was in the build from v2.1.138 and was gone by v2.1.242.

What it is

Five more environment variables, including stream and byte watchdogs, can be set in settings.json.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.248.

Presence across releases

2.1.138 – 2.1.159 20 releases in the build

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.

Documentation pages

A reference table page is one whose own table defines this name, and it is where the description above came from. A page that mentions it carries the name somewhere in its text and may say nothing about it at all. Every page carrying it.

Names beside it

Every environment variable in the inventory starting claude_enable, up to twelve of them.

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.
