Persistent execution of package-supplied statusline code across Claude Code projects. - **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:** 8.15.1 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installation mutates the user's global Claude Code configuration without a user command or consent.

It registers a package-controlled command to run in every Claude Code session. - **Trigger:** npm postinstall - **Impact:** Persistent execution of package-supplied statusline code across Claude Code 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:** 2026-08-05T21:50:46.253Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** global Claude settings command injection - **Attack narrative:** On npm installation, the postinstall entry point calls installGlobalStatusline without prompting. That function copies package scripts to ~/.claude and replaces the global settings.json statusLine with a command invoking them. Claude Code then executes the package-controlled command for every session, including unrelated projects. - **Rationale:** This is unconsented postinstall mutation of a broad, foreign AI-agent control surface. The benign-looking statusline purpose does not remove the persistent global command injection. - **Files touched:** ~/.claude/statusline.sh, ~/.claude/statusline.py, ~/.claude/settings.json ### 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 unconditionally calls installGlobalStatusline during install., hooks-installer copies scripts into ~/.claude and overwrites settings.statusLine., The installed statusline is configured for every Claude Code session. - **Evidence against:** No exfiltration or unrelated network endpoint was found in the inspected install/statusline path., The installed payload is a local statusline script, not a remote loader. ## Public findings ### 1.
