Two new environment variables let you configure Claude Code for multi-repo development workflows.
Usage

export CLAUDE_CODE_BASE_REFS='{"frontend": "origin/main", "backend": "origin/develop"}'
claudeDetails
CLAUDE_CODE_REPO_CHECKOUTS— JSON map of name-to-path entries for repository checkouts. Claude Code tracks branches across all configured repos.CLAUDE_CODE_BASE_REFS— JSON map specifying the base git ref for each checkout (used for diff comparisons and bundle generation).- Both values are cached per session with singleton initialization.
Evidence
Repo checkouts env var (search for "CLAUDE_CODE_REPO_CHECKOUTS") and base refs (search for "CLAUDE_CODE_BASE_REFS")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
