It can also run an automatic project upgrade in the installation working directory. - **Trigger:** npm installation runs the postinstall hook. - **Impact:** Package-controlled prompts and settings can affect several AI coding-agent environments without an explicit setup command. - **Evidence paths:** package.json, scripts/install-skills.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T09:47:04.037Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall fan-out of skills and agents plus automatic AI-agent configuration and project mutation. - **Attack narrative:** On installation, package.json launches scripts/install-skills.mjs. That script iterates its AI-platform profiles and installs package-controlled skills, installs agent prompt files, and changes Claude settings when no output style is set. It also detects a prior project state and invokes an automatic upgrade command against that project. These are unconsented postinstall changes to broad AI-agent control surfaces. - **Rationale:** This is a concrete automatic lifecycle hook that broadly mutates foreign AI-agent configuration and extension directories, with an additional automatic project upgrade. The absence of observed network theft does not remove the install-hook abuse. - **Files touched:** ~/.claude/skills/\*, ~/.codex/skills/\*, ~/.trae/skills/\*, ~/.cursor/skills/\*, ~/.claude/agents/\*, ~/.claude/settings.json, ~/.peaks/config.json, \/.peaks/\* ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs its installer automatically after npm installation., The installer fans package skills into multiple AI-agent home directories., It installs agent prompt files into Claude's agent loader directory., It changes Claude's settings to select a package-provided output style., It can automatically invoke a project upgrade command during installation. - **Evidence against:** No network request or credential collection was found in the inspected installer., The installer includes path and file-type checks intended to avoid unsafe overwrites. ## Affected versions and remediation This report applies to peaks-loop@4.0.38. - Avoid installing peaks-loop@4.0.38. 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.
