It also changes the Windows PowerShell profile. - **Trigger:** npm postinstall - **Impact:** All Claude Code sessions may execute package-installed statusline code; Windows shells receive persistent PATH changes. - **Evidence paths:** package.json, src/scripts/global-install.js, src/utils/hooks-installer.js, framework/hooks/claude-code/statusline.sh, framework/hooks/claude-code/statusline.py - **Review source:** ai\_review - **Reviewed:** 2026-07-28T22:40:35.140Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented global AI-agent configuration and shell-profile mutation - **Attack narrative:** During npm postinstall, the package copies its statusline scripts into ~/.claude and replaces the global Claude Code statusLine setting to execute them for every session, without an explicit user command. On Windows it also appends PATH logic to PowerShell profiles. This is a broad foreign AI-agent control-surface mutation at install time. - **Rationale:** The install-time global Claude Code configuration write meets the blocking policy regardless of the statusline's presently benign behavior. No credential exfiltration was found in the inspected statusline source. - **Files touched:** ~/.claude/statusline.sh, ~/.claude/statusline.py, ~/.claude/settings.json, ~/Documents/PowerShell/Microsoft.PowerShell\_profile.ps1, ~/Documents/WindowsPowerShell/Microsoft.PowerShell\_profile.ps1 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs src/scripts/global-install.js as postinstall., global-install.js invokes installGlobalStatusline without user consent., hooks-installer.js overwrites ~/.claude/settings.json statusLine globally., Postinstall copies executable statusline.sh/.py into ~/.claude/., Postinstall also modifies Windows PowerShell profile PATH. - **Evidence against:** Statusline source only formats stdin/git/project state; no exfiltration found., Other MCP/network actions are reachable through explicit CLI setup commands. ## Public findings ### 1.
