Claude Code routes Grep, Glob through Bash

Claude Code 2.1.117 replaces native Glob and Grep tools on macOS and Linux native builds with embedded bfs and ugrep routed through Bash, while Windows and npm installs are unchanged. The change aims to speed searches by avoiding separate tool round trips, but early users are flagging workflow and permission side effects.

// ANALYSIS

This is a performance-minded agent tooling change with a real ergonomics bill: faster search is useful, but moving core exploration into Bash changes how developers audit, hook, and constrain agent behavior.

–Native-build users may see fewer explicit Grep/Glob calls and more Bash-mediated search behavior
–Teams with hooks, allowlists, or monitoring keyed to tool names need to revisit their Claude Code policies
–The npm and Windows carve-out makes behavior less uniform across developer environments
–The update lands alongside broader 2.1.117 improvements for subagents, plugins, resume flows, and model defaults
