CLAUDE_CODE_AUTO_MODE_OUTCOME_CODES
A Claude Code environment variable, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.
The switch controlling outcome codes in auto mode now runs through a wrapper with an empty branch.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.221.

First cited
2The earliest release whose published evidence quoted CLAUDE_CODE_AUTO_MODE_OUTCOME_CODES was v2.1.221, 3 Aug 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table below.
Presence across releases
0The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.
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.
