The package has a real agent-control-surface mutation risk because npm postinstall installs skills and workflow hooks into local Codex/Claude locations. Inspection did not find payload execution, credential theft, or exfiltration, and the behavior is aligned with the package's stated purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 86.0% - **Started:** 2026-07-01T07:55:17.495Z - **Finished:** 2026-07-01T07:57:02.931Z - **Download time:** 770 ms - **Static scan time:** 322 ms - **AI review time:** 104343 ms - **Total time:** 105436 ms ## Security analysis ### Published attack-surface review - **Summary:** The package has a real agent-control-surface mutation risk because npm postinstall installs skills and workflow hooks into local Codex/Claude locations. Inspection did not find payload execution, credential theft, or exfiltration, and the behavior is aligned with the package's stated purpose. - **Trigger:** npm install postinstall, loopx install-skills, loopx repair-install, or plugin install - **Impact:** Local agent workflow files and Claude hook settings may be changed; installed hooks provide advisory context and version notices. - **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, src/codex-exec-runtime.mjs, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-01T07:57:02.931Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** agent skill/hook installer with optional user-invoked Codex subprocess runner - **Attack narrative:** On install, the lifecycle script copies bundled workflow skills and hook scripts into user agent directories and may register a Claude UserPromptSubmit hook. The hook code reads local loopx workflow state and prints bounded advisory text, plus a best-effort npm registry version check. This is risky agent-surface mutation during install, but source inspection did not show concealed malicious behavior or data exfiltration. - **Rationale:** Static inspection supports a warn-level verdict for install-time mutation of AI-agent hooks and a dangerous user-invoked Codex execution helper, but the behavior is documented and package-aligned with no confirmed malicious payload. No publish block is justified from the inspected source. - **Files touched:** ~/.agents/skills/\, ~/.agents/.skill-lock.json, ~/.codex/hooks/codex-workflow-hook.mjs, ~/.claude/skills/\, ~/.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:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json runs postinstall: node scripts/install-skills.mjs, src/install-discovery.mjs installs bundled skills and hook scripts for Codex/Claude by default, src/install-discovery.mjs can update ~/.claude/settings.json UserPromptSubmit hook, src/codex-exec-runtime.mjs has user-invoked codex exec with --dangerously-bypass-approvals-and-sandbox - **Evidence against:** scripts/codex-workflow-hook.mjs and scripts/claude-workflow-hook.mjs emit advisory workflow context, not hidden commands, README.md describes loopx as a skill/hook installer for agentic coding assistants, No credential harvesting, filesystem secret search, or exfiltration found, Network code is a version check to the npm registry and is opt-out via LOOPX\_NO\_UPDATE\_CHECK, Postinstall can be skipped via LOOPX\_SKIP\_POSTINSTALL=1 or LOOPX\_POSTINSTALL=0 ## Public findings ### 1.
