Installation silently changes the global Claude Code command configuration. The change applies outside the consuming project. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-29T19:42:37.611Z - **Finished:** 2026-08-29T19:45:04.433Z - **Download time:** 753 ms - **Static scan time:** 3420 ms - **AI review time:** 142647 ms - **Total time:** 146822 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation silently changes the global Claude Code command configuration. The change applies outside the consuming project. - **Trigger:** npm installation runs postinstall automatically. - **Impact:** A package-controlled command runs during Claude Code sessions across the user's projects. - **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:** 2026-08-29T19:45:04.433Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Copies scripts to ~/.claude and replaces the global statusLine command. - **Attack narrative:** Installing the package runs postinstall without a user command. That hook copies executable status-line scripts into ~/.claude and writes ~/.claude/settings.json so Claude Code invokes the package-controlled command globally. This changes a broad AI-agent control surface rather than configuring only a project owned by the package. - **Rationale:** The automatic postinstall mutates the user's global Claude Code configuration and installs a command that applies to every session. This is an unconsented broad AI-agent control-surface change, so it meets the install-hook blocking policy. - **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:** The package declares an automatic postinstall hook., The postinstall immediately installs a global Claude status line., The installer copies package scripts into the user's global Claude directory., It overwrites the global Claude statusLine command, affecting every Claude Code session. - **Evidence against:** The installed status line source contains no network or credential-exfiltration code., No runtime self-dependency is declared. ## Public findings ### 1.
