Changes default AI-agent behavior across the user's Codex and Claude environments. - **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:** 0.8.4 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall mutates broad Codex and Claude instruction files and installs skills into user agent directories. The mutation occurs without an explicit setup command or consent prompt. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 97.0% - **Started:** 2026-08-08T11:33:15.844Z - **Finished:** 2026-08-08T11:34:00.498Z - **Download time:** 762 ms - **Static scan time:** 265 ms - **AI review time:** 43626 ms - **Total time:** 44654 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall mutates broad Codex and Claude instruction files and installs skills into user agent directories. The mutation occurs without an explicit setup command or consent prompt. - **Trigger:** npm installation, unless LOOPX\_SKIP\_POSTINSTALL=1 or LOOPX\_POSTINSTALL=0 is set beforehand. - **Impact:** Changes default AI-agent behavior across the user's Codex and Claude environments. - **Evidence paths:** package.json, scripts/install-skills.mjs, src/install-discovery.mjs, templates/working-agreement.md - **Review source:** ai\_review - **Reviewed:** 2026-08-08T11:34:00.498Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies skills and appends managed agent-routing blocks - **Attack narrative:** Installing the package automatically invokes scripts/install-skills.mjs. Its default target set is Codex and Claude; installation copies bundled skills into user-level agent directories and then calls installAgentGuidance. That function always upserts a loopx routing block into ~/.codex/AGENTS.md and ~/.claude/CLAUDE.md, broad instruction/control surfaces for other agent sessions. The optional CLI prompt only governs additional context guidance, not this postinstall routing mutation. - **Rationale:** The package performs unconsented postinstall mutation of foreign, broad AI-agent control surfaces. This meets the blocking policy despite no observed data exfiltration or remote payload execution. - **Files touched:** ~/.agents/skills/\*, ~/.agents/.skill-lock.json, ~/.claude/skills/\*, ~/.claude/CLAUDE.md, ~/.codex/AGENTS.md, ~/.loopx/template-hashes.json ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall installer., scripts/install-skills.mjs installs targets by default., src/install-discovery.mjs defaults targets to codex and claude., installBundledSkills unconditionally calls installAgentGuidance., installAgentGuidance writes ~/.codex/AGENTS.md and ~/.claude/CLAUDE.md., Managed routing guidance is appended during install without a user command. - **Evidence against:** No credential harvesting or exfiltration found., No shell/child-process or dynamic-code execution found., Network fetch is limited to explicit version checking in src/version-check.mjs. ## Public findings ### 1.
