Claude Code 2.1.160: Security Hardening for Shell Startup Files and Ultracode Keyword Rename

Claude Code Changelog·high signal

Released June 2, Claude Code 2.1.160 adds mandatory prompts before writing to shell startup files (.zshenv, .zlogin, .bash_login) and ~/.config/git/ to prevent unintended command execution. acceptEdits mode now also prompts before writing build-tool configs that grant code execution (.npmrc, .yarnrc, bunfig.toml, .bazelrc, .pre-commit-config.yaml, .devcontainer/). The dynamic-workflow trigger keyword was renamed from 'workflow' to 'ultracode' — the old word no longer triggers a run, and the keyword is highlighted violet in the prompt input.
