Subsequent normal CLI use restores those agent-control surfaces. - **Trigger:** npm global installation, followed by any ordinary vibe command if the surfaces are absent or stale. - **Impact:** Package-controlled instructions and commands become active in broad AI-agent home directories without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.js, dist/install/global.js, dist/cli.js, hooks/notify.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T20:12:25.866Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall agent configuration mutation and persistent hook installation. - **Attack narrative:** The postinstall hook activates during a global npm installation and calls global setup. That setup writes package cards and skills into Claude and Codex directories and adds hooks that invoke package code on agent tool events. The CLI also repairs these surfaces whenever it is run. This is an automatic, persistent mutation of broad AI-agent control surfaces rather than an explicit user setup action. - **Rationale:** The package has a concrete postinstall path that installs and persists package-controlled AI-agent instructions and command hooks in user home directories. This meets the policy for malicious install-hook abuse even though no secret exfiltration was found. - **Files touched:** scripts/postinstall.js, dist/install/global.js, hooks/notify.js, .claude/CLAUDE.md, .claude/skills/vibe, .claude/settings.json, .codex/AGENTS.md, .codex/skills/vibe, .codex/hooks.json ### 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., On global installation, the script calls setupGlobal without user interaction., Global setup installs cards, skills, and command hooks into detected Claude and Codex home directories., The installed hooks run package code for agent tool events, and ordinary CLI commands repair removed surfaces. - **Evidence against:** The install hook is limited to global npm installs., No credential exfiltration or unrelated network endpoint was found in the install path. ## Public findings ### 1.
