Creates a persistent, broad AI-agent execution surface outside the installed project. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 8.20.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall modifies the global Claude Code configuration and installs a command invoked in every Claude Code session. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-12T00:25:18.853Z - **Finished:** 2026-08-12T00:27:27.697Z - **Download time:** 754 ms - **Static scan time:** 2845 ms - **AI review time:** 125243 ms - **Total time:** 128844 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall modifies the global Claude Code configuration and installs a command invoked in every Claude Code session. - **Trigger:** npm installation of the package - **Impact:** Creates a persistent, broad AI-agent execution surface outside the installed project. - **Evidence paths:** package.json, src/scripts/global-install.js, src/utils/hooks-installer.js, framework/hooks/claude-code/statusline.py - **Review source:** ai\_review - **Reviewed:** 2026-08-12T00:27:27.697Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented global Claude statusline registration - **Attack narrative:** Installing the package runs its postinstall script, which copies package-provided statusline scripts into ~/.claude and overwrites the global statusLine command in ~/.claude/settings.json. This causes package-controlled code to run for every Claude Code session, including unrelated projects, without an explicit user command or consent. The same postinstall also attempts to modify PowerShell profiles on Windows. - **Rationale:** The postinstall creates a foreign, global Claude Code control surface rather than limiting setup to an explicit CLI command or the target project. This meets the blocking policy despite no confirmed exfiltration endpoint. - **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 executes global-install.js as postinstall., Postinstall unconditionally invokes a global Claude statusline installer., Installer writes ~/.claude/settings.json with a command executed by every Claude Code session. - **Evidence against:** The installed statusline source declares itself stateless and has no network API usage., MCP credential/network setup is reached through interactive CLI setup, not postinstall. ## Public findings ### 1.
