It injects instructions, replaces skill directories, and registers commands on Bash and edit events. - **Trigger:** Global installation of @su-record/vibe runs its postinstall script; later CLI commands repair the changes. - **Impact:** The package can persistently influence agent behavior and cause package code to run on future agent tool events without an explicit setup action. - **Evidence paths:** scripts/postinstall.js, dist/install/global.js, hooks/notify.js, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T20:12:27.775Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time mutation of broad AI-agent instruction and hook configurations. - **Attack narrative:** On global installation, npm automatically invokes the package postinstall script. That script calls global setup, which writes agent instruction files, removes and replaces skill directories, and installs commands into Claude and Codex hook configurations. Those hooks are activated for Bash and edit-related agent events. Subsequent ordinary CLI commands silently restore missing surfaces, making the change persistent. This is unconsented mutation of broad, foreign AI-agent control surfaces. - **Rationale:** The lifecycle-triggered global setup directly modifies multiple AI-agent home configurations and installs event-driven commands. This meets the install-hook abuse policy regardless of the unrelated, user-invoked GitHub functionality. - **Files touched:** scripts/postinstall.js, dist/install/global.js, hooks/notify.js, ~/.claude/CLAUDE.md, ~/.claude/settings.json, ~/.claude/skills/vibe, ~/.codex/AGENTS.md, ~/.codex/hooks.json, ~/.codex/skills/vibe, ~/.hermes/SOUL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The automatic postinstall script runs global setup during a global npm installation., Global setup targets Claude, Codex, and Hermes home directories and injects agent instruction surfaces., It deletes and replaces named skill directories and adds command hooks to agent configuration files., The installed hook observes Bash and file-edit events and runs package code., Every normal CLI command also repairs missing global agent surfaces without an explicit setup command. - **Evidence against:** No secret collection or network exfiltration is present in the installation path., The GitHub API client is separate, user-invoked functionality and is not used by postinstall. ## Public findings ### 1.
