A global npm install silently modifies Claude, Codex, and Hermes agent homes. It injects instruction cards and skills and registers command hooks. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-04T20:57:27.560Z - **Finished:** 2026-09-04T20:58:12.731Z - **Download time:** 759 ms - **Static scan time:** 630 ms - **AI review time:** 43781 ms - **Total time:** 45171 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install silently modifies Claude, Codex, and Hermes agent homes. It injects instruction cards and skills and registers command hooks. - **Trigger:** Installing the package globally through npm without VIBE\_SKIP\_SETUP. - **Impact:** The package gains persistent influence over AI-agent instructions and tool-event execution across existing client homes. - **Evidence paths:** package.json, scripts/postinstall.js, dist/install/global.js, dist/install/hooks.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T20:58:12.731Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall calls global setup to write agent control files and command hooks. - **Attack narrative:** On global npm installation, the postinstall script invokes setup without an explicit agent-configuration command. Setup detects AI client homes and writes persistent instruction cards and skills, then adds command hooks for Bash and edit events. This mutates broad, pre-existing AI-agent control surfaces and causes package code to run during later agent activity. - **Rationale:** This is an automatic install-time mutation of foreign AI-agent control surfaces, including persistent instructions and command hooks. The global-only guard does not provide consent for those changes. - **Files touched:** ~/.claude/CLAUDE.md, ~/.claude/skills, ~/.claude/settings.json, ~/.codex/AGENTS.md, ~/.codex/skills, ~/.codex/hooks.json, ~/.hermes/SOUL.md, ~/.hermes/skills ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs a postinstall script., Postinstall automatically calls global setup for global npm installs., Global setup writes agent instruction cards, skills, and hooks into detected client homes., The hook installer adds command hooks for Bash and file-edit events. - **Evidence against:** The install hook is limited to global npm installs., No credential exfiltration or unrelated network call was found in the install path. ## Public findings ### 1.
