It installs package instructions, skills, and command hooks that run on session and tool events. - **Trigger:** Global installation of the package with npm lifecycle scripts enabled. - **Impact:** The package gains persistent behavior-bearing execution and instruction surfaces in Claude and Codex agent environments without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.js, dist/install/global.js, dist/install/hooks.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T05:10:02.786Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic injection of agent instructions, skills, and command hooks. - **Attack narrative:** On global installation, npm runs scripts/postinstall.js, which calls setupGlobal. That routine detects agent homes, defaults to Claude if none exists, and installs a card, skills, and hooks. The hooks add package command execution for session start, stop, and read, shell, and write-related tool events. This is an unconsented install-time mutation of broad AI-agent control surfaces. - **Rationale:** The automatic postinstall chain writes behavior-bearing configuration into Claude and Codex homes and registers command hooks. This meets the install-hook abuse policy even though no automatic network exfiltration was found. - **Files touched:** ~/.claude/CLAUDE.md, ~/.claude/skills/, ~/.claude/settings.json, ~/.codex/AGENTS.md, ~/.codex/skills/, ~/.codex/hooks.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs a postinstall script during global npm installation., The postinstall script imports and invokes global agent setup without an explicit user command., Global setup targets detected agent homes and defaults to Claude when none are found., It adds instruction cards, skills, and command hooks to agent configuration files., The hook configuration runs package code on agent session and tool events. - **Evidence against:** No automatic network request or credential exfiltration was found in the install path., GitHub API access is confined to a separate runtime client and uses an existing token only for GitHub requests. ## Affected versions and remediation This report applies to @su-record/vibe@4.1.29. - Avoid installing @su-record/vibe@4.1.29. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
