Package-controlled prompts become discoverable by installed AI-agent hosts. - **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:** 1.20.1 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm installation automatically invokes the installer. The installer places package skills in AI-agent discovery/control directories, including Cursor by default and a cross-agent location. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 95.0% - **Started:** 2026-08-09T00:40:10.523Z - **Finished:** 2026-08-09T00:41:15.160Z - **Download time:** 510 ms - **Static scan time:** 1136 ms - **AI review time:** 62989 ms - **Total time:** 64637 ms ## Security analysis ### Published attack-surface review - **Summary:** npm installation automatically invokes the installer. The installer places package skills in AI-agent discovery/control directories, including Cursor by default and a cross-agent location. - **Trigger:** npm postinstall - **Impact:** Package-controlled prompts become discoverable by installed AI-agent hosts. - **Evidence paths:** package.json, dist/lib/install.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T00:41:15.160Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented AI-agent skill installation - **Attack narrative:** Installing the npm package runs its postinstall installer without an explicit user command. The package documents that this defaults to Cursor and writes package-controlled skills into multiple AI-agent discovery directories, including the broad ~/.agents path. This creates an unconsented foreign AI-agent control-surface mutation; obfuscation prevents trustworthy granular review of the installer. - **Rationale:** The install-time, default cross-agent mutation meets the firewall block policy even though no exfiltration endpoint was confirmed. The documented behavior and installer source directly support the finding. - **Files touched:** package.json, dist/lib/install.js, ~/.cursor/skills/\/SKILL.md, ~/.claude/skills/\/SKILL.md, ~/.claude/commands/, ~/.codex/skills/\/SKILL.md, ~/.grok/skills/\/SKILL.md, ~/.codeium/windsurf/skills/\/SKILL.md, ~/.agents/skills/\/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs dist/lib/install.js automatically in postinstall., README.md states postinstall installs Cursor by default and a cross-agent path., README.md:37-42 maps installs to ~/.cursor, ~/.claude, ~/.codex, ~/.grok, ~/.codeium/windsurf, and ~/.agents., dist/lib/install.js imports platform targets and filesystem modules; its obfuscated source implements install/remove., All distributed executable JS is deliberately obfuscated, limiting transparent audit. - **Evidence against:** No network endpoint or credential-exfiltration behavior was confirmed from inspected sources., The documented payload consists of package-provided SKILL.md design-persona files. ## Public findings ### 1.
