Unclear It is not clear what this list is used for or whether the feature behind these names is in use.
What
Environment variables are named values passed to a program when it starts. Claude Code keeps a list of such names, which already includes CLAUDE_CODE_RELAUNCH_HOME_TRUST and CLAUDE_CODE_PROJECT_DIR_NAME. Seven names are added:
CLAUDE_PTY_HOST_EXECCLAUDE_BG_PTY_AUTHCLAUDE_BG_RV_AUTHCLAUDE_BG_CLAIM_AUTHCLAUDE_BG_RENDEZVOUS_SOCKCLAUDE_BG_BACKENDCLAUDE_BG_TCC_DISCLAIMED
A separate new name, CLAUDE_CODE_STREAMED_BUMBLEBEE_TEXT, also appears in another list of environment variables.
Why
The names suggest work on background sessions that sign in to each other through a shared connection point. Nothing here shows that they do anything for you yet.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
