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_RUNNER_USE_GIT_PROXY

A Claude Code environment variable, read out of the shipped bundle. It has been in the build since v2.1.224, including the newest one read.

What it is

Nobody has written a line about this one. It is not in any of Anthropic's reference tables and no changelog entry here carries a description of it. It is in the build, which is the whole of what this page can claim.

Presence across releases

ReleasesReadingDeclared typeDefault
2.1.245 – 2.1.250 5 releases never mined
2.1.224 – 2.1.243 19 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.

Changelog entries naming it

No changelog entry here has ever named it. That is a statement about what has been written, not about the name: it has been in the build since v2.1.224 without anybody writing a line about it.

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_runner, up to twelve of them.

CLAUDE_RUNNER_ACTIVITY_FDNo description from anybody. 2.1.196 CLAUDE_RUNNER_CLAUDE_BINThe runner writes a code-sign helper script, using CLAUDE_RUNNER_CLAUDE_BIN if you set it. never mined CLAUDE_RUNNER_CLIENT_PLATFORMOdd platform labels from the runner are rejected or replaced with "unknown" instead of exported. never mined CLAUDE_RUNNER_DISABLE_AWAITING_ACTION_OVERRIDENo description from anybody. 2.1.200 CLAUDE_RUNNER_FAIL_FAST_FETCHTwo env vars change how runner git fetches handle retries and stalled delta resolution. never mined CLAUDE_RUNNER_FETCH_DEPTHFull git checkout machinery for self-hosted runners now ships, but you cannot reach it interactively. 2.1.172 CLAUDE_RUNNER_SESSION_UUIDRunner hooks now get CLAUDE_RUNNER_SESSION_UUID and CLAUDE_CODE_REMOTE_SESSION_UUID so your scripts can key on the session. never mined CLAUDE_RUNNER_SKIP_GIT_VERIFYNo description from anybody. 2.1.224

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.
