Optimizing Claude Code for monorepos

Anthropic published guidelines for configuring Claude Code in large projects and monorepos. The tool now supports flexible context limiting to save tokens and boost performance.

Developers can partition instructions using local CLAUDE.md files in subdirectories. .claude/settings.json settings let you exclude paths via claudeMdExcludes and block loader reads with permissions.deny.

Sparse-checkout in Git is activated with worktree.sparsePaths, downloading only required folders instead of the entire repo. Access to adjacent packages is configurable via additionalDirectories.

This approach solves context overflow issues in massive codebases. Developers get targeted code access without excess token spend.
