This mutates a broad foreign agent control surface without an explicit user command. - **Trigger:** npm postinstall during package installation - **Impact:** The package can place its instructions into active AI-agent skill directories, affecting future agent behavior. - **Evidence paths:** package.json, scripts/postinstall.js, dist/services/skill-installer.js - **Review source:** ai\_review - **Reviewed:** 2026-09-03T18:26:59.495Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic multi-agent skill deployment - **Attack narrative:** On npm installation, postinstall runs the CLI with skill install. With no agent selection provided, the installer detects configured AI tools from a broad registry and copies its bundled skill into their skills directories. This is an unconsented install-time mutation of unrelated AI-agent control surfaces. - **Rationale:** The package has a concrete automatic postinstall chain that deploys content across broad, foreign AI-agent configuration directories. Its conflict safeguards do not make the automatic cross-agent mutation consensual. - **Files touched:** scripts/postinstall.js, dist/index.js, dist/services/skill-installer.js, skill/SKILL.md, ~/.\/skills/cbs-4px-merchant-cli ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The automatic postinstall lifecycle hook launches the CLI skill installer without user input., The installer targets active configurations for many unrelated AI coding tools, including Codex, Claude Code, Cursor, and others., The installer creates target directories and copies bundled skill files into each selected AI-agent skills directory. - **Evidence against:** The installer avoids overwriting directories it identifies as foreign unless forced., The observed network code is for the declared merchant API and npm update checks, not the lifecycle mutation. ## Public findings ### 1.
