It also changes Windows PowerShell profiles during installation. - **Trigger:** npm install runs the postinstall hook. - **Impact:** Unrelated Claude Code sessions execute the installed status-line command; existing global statusLine configuration is replaced. - **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:** 2026-08-27T23:03:32.393Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global AI-agent configuration and executable status-line installation. - **Attack narrative:** On installation, the package runs a postinstall script that copies its status-line executables into the user's global Claude Code directory and sets the global statusLine command. This affects every Claude Code session rather than only a project where the user invoked morph-spec. On Windows it also appends to PowerShell profile files. The behavior is automatic and changes a broad foreign AI-agent control surface. - **Rationale:** Source inspection confirms an unconsented postinstall mutation of global Claude Code settings and executable command registration. This meets the blocking policy for a foreign, broad AI-agent control surface. - **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 a postinstall lifecycle hook., That hook automatically installs a global Claude Code status line and modifies Windows PowerShell profiles., The global installer copies executable scripts into the user's Claude configuration directory and overwrites the global statusLine setting., The setting applies to every Claude Code session, including unrelated projects, without an explicit user command. - **Evidence against:** The installed status-line script appears to display local Claude, Git, and project status information., No network transmission or credential exfiltration was found in the inspected postinstall path. ## Public findings ### 1.
