Code Execution

This lets Claude run Python locally to handle bulk operations without burning through your token budget. When you're refactoring 50 files or auditing a hundred modules, it executes everything on your machine and returns just the summary. The APIs cover filesystem operations, code analysis (metadata only, not full source), transformations like renaming identifiers across your codebase, and basic git commands. The token savings are legitimate: a 100-file operation drops from 150K tokens to around 1K. It activates automatically when you mention bulk work or efficiency, though you can also import the runtime directly. The tradeoff is setup and trusting local execution, but if you're doing repetitive operations across many files, it's the difference between hitting rate limits and getting work done.
