2. Claude Code v2.1.160 Adds Security Prompts for Sensitive Config Files

Anthropic. Claude Code v2.1.160, tagged June 2, 2026, introduces confirmation dialogs before writing to shell startup files (.zshenv, .zlogin, .bash_login) and Git config directories, guarding against unintended command-execution side effects. The release also adds safeguards in acceptEdits mode to prompt before modifying build-tool config files that grant code execution (e.g., .npmrc, .bazelrc), streamlines file reading so a single-file grep satisfies read-before-edit requirements, and renames the dynamic workflow trigger keyword from “workflow” to “ultracode” with violet highlighting.
