On some platforms it can also invoke OS package installation. - **Trigger:** npm postinstall - **Impact:** Every Claude Code session can execute the installed statusline command; installation may prompt for elevated package-manager access. - **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:** 2026-08-22T00:01:31.400Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** global Claude settings mutation and dependency installation - **Attack narrative:** A normal npm installation executes the postinstall script without an explicit setup command. It creates the user-wide Claude configuration directory, copies executable statusline scripts, and registers a command in global Claude settings, affecting all Claude Code sessions rather than only this package's project. Its Windows statusline path can invoke automatic Python installation through system package managers when Python is absent. This is an unconsented, broad AI-agent control-surface mutation at install time. - **Rationale:** Source confirms an automatic postinstall write to global Claude Code configuration and executable command registration. That broad user-wide control-surface change meets the blocking policy despite no confirmed exfiltration. - **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:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall runs a global installer automatically., Installer creates ~/.claude and overwrites its global statusLine command., Windows setup may auto-install Python through system package managers, including sudo on Linux code paths. - **Evidence against:** No credential harvesting or package-controlled exfiltration was confirmed., The copied statusline is a local display script. ## Public findings ### 1.
