It adds instructions, skills, and command hooks that run on future Claude or Codex tool events. - **Trigger:** Installing the package globally; later ordinary vibe CLI commands can repair missing surfaces. - **Impact:** Changes the behavior-bearing configuration of external AI-agent clients without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.js, dist/install/global.js, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T20:12:20.380Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall-driven AI-agent configuration and hook injection. - **Attack narrative:** The package declares postinstall. During a global installation it automatically invokes global setup, which discovers AI-agent client homes, creates or edits instruction files, copies skills, and adds PreToolUse and PostToolUse commands to agent settings. If no supported home exists, it selects Claude as the default target. Its CLI also restores these surfaces during normal commands. This is unconsented install-time mutation of broad external AI-agent control surfaces. - **Rationale:** The verified postinstall chain changes Claude and Codex user-level control surfaces without an explicit user setup action. That concrete install-hook behavior meets the publish-block policy even though no secret exfiltration was found in the inspected code. - **Files touched:** ~/.claude/CLAUDE.md, ~/.claude/skills, ~/.claude/settings.json, ~/.codex/AGENTS.md, ~/.codex/skills, ~/.codex/hooks.json ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a postinstall script., On global installation, the script imports and runs global setup without a user command., Setup writes command hooks into Claude and Codex agent settings., It installs agent instructions and skills in detected client home directories, defaulting to Claude when none exist., The CLI also repairs missing global agent surfaces on ordinary commands. - **Evidence against:** The postinstall path is limited to global npm installations and can be skipped with an environment variable., The installed hook source appears to emit warnings and exits successfully; no credential exfiltration was found in the inspected paths. ## Public findings ### 1.
