Anthropic introduced subagent sandbox isolation to its CLI tool Claude Code. When orchestrating large refactors, the master agent can spawn lightweight subagents into isolated scratch environments to write tests, update documentation, and verify patches in parallel before merging into a unified Git commit.

Key Takeaways

  • ✓Claude Code spawns parallel isolated subagents for decoupled task execution.
  • ✓Isolated scratch worktrees prevent unverified test artifacts from polluting repos.
  • ✓Automatically aggregates test results into clean, standard Git commit history.
