Install-time code mutates local AI-agent control surfaces without an explicit npm-install consent step. It installs skills and hook files for Codex and Claude and registers a Claude prompt hook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-07-01T18:07:57.633Z - **Finished:** 2026-07-01T18:08:59.144Z - **Download time:** 765 ms - **Static scan time:** 331 ms - **AI review time:** 60414 ms - **Total time:** 61511 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code mutates local AI-agent control surfaces without an explicit npm-install consent step. It installs skills and hook files for Codex and Claude and registers a Claude prompt hook. - **Trigger:** npm install postinstall - **Impact:** Can alter future Codex/Claude agent behavior for the user by adding bundled skills, hook scripts, and Claude hook settings. - **Evidence paths:** package.json, scripts/install-skills.mjs, src/install-discovery.mjs, scripts/codex-workflow-hook.mjs, scripts/claude-workflow-hook.mjs, src/version-check.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-01T18:08:59.144Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented AI-agent skill and hook installation - **Attack narrative:** On npm install, the postinstall script imports the installer and runs installSkillsForTargets with default Codex and Claude targets. That writes bundled skill directories plus managed hook scripts into user agent locations, and for Claude merges a UserPromptSubmit hook command into settings.json. This is package-related behavior, but it is activated by lifecycle install rather than an explicit user CLI command. - **Rationale:** The package does not show data theft, destructive behavior, or remote payload loading, but it performs unconsented lifecycle mutation of AI-agent skill/hook surfaces. For an upstream firewall, that is concrete install-time agent control-surface abuse even if the content is mostly workflow-oriented. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** ~/.agents/skills/\*, ~/.agents/.skill-lock.json, ~/.agents/.loopx-template-hashes.json, ~/.codex/hooks/codex-workflow-hook.mjs, ~/.claude/skills/\*, ~/.claude/.loopx-skill-lock.json, ~/.claude/.loopx-template-hashes.json, ~/.claude/hooks/loopx-workflow-hook.mjs, ~/.claude/settings.json, ~/.loopx/template-hashes.json - **Network endpoints:** https://registry.npmjs.org/@ai-content-space/loopx/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json runs postinstall: node scripts/install-skills.mjs, scripts/install-skills.mjs calls installSkillsForTargets without prompting unless opt-out env is set, src/install-discovery.mjs default targets are codex and claude, src/install-discovery.mjs copies skills into ~/.agents/skills and ~/.claude/skills, src/install-discovery.mjs installs hook scripts under .codex/hooks and .claude/hooks, src/install-discovery.mjs writes Claude UserPromptSubmit hook settings - **Evidence against:** No credential harvesting or secret-specific file scans found, No obfuscated payloads or dynamic remote code loading found, Only network endpoint found is npm registry update check, Child process use is CLI-driven Codex/git workflow functionality, skills/debug/find-polluter.sh is a user-invoked test helper ## Public findings ### 1.
