CLAUDE_CODE_DESKTOP_APP_VERSION
A Claude Code environment variable, read out of the shipped bundle.
It has been in the build since v2.1.267, including the newest one read.
Version of the Claude desktop app, read only when CLAUDE_CODE_ENTRYPOINT is claude-desktop or local-agent. It is sent as anthropic-client-version with anthropic-client-platform: desktop_app on API requests (unless either header is already set) and added to event metadata as desktopAppVersion.
Not Anthropic's. Written by Claude Opus 5.5 from reading the v2.1.286 bundle, and it can be wrong.

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 v2.1.267 without anybody writing a line about it.

No release's published evidence quotes this name. The ledger indexes the Evidence lines of every changelog on this site, so this says nobody here has ever quoted it; it says nothing about how old the name is.

One row per release since the first build this name was read out of. Absent means the build was read and the name was not in it, never mined means no bundle for that release was ever archived, and a declared type or a default is only ever what that release's own bundle stated.

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.
