It installs package-supplied skills and agents across all configured platforms without an explicit user command or platform selection. - **Trigger:** Installing peaks-loop runs the npm postinstall lifecycle hook. - **Impact:** Package content can alter the behavior and available instructions of several local AI coding tools. - **Evidence paths:** package.json, scripts/install-skills.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-12T11:31:27.494Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Cross-platform AI-agent skill, agent, configuration, and output-style installation. - **Attack narrative:** During npm installation, package.json invokes scripts/install-skills.mjs. That script defines home-directory integration paths for several AI tools, then loops through every platform to link bundled skills. Its lifecycle entrypoint also installs bundled agents, writes user configuration, and registers an output style. This is unconsented postinstall mutation of broad, foreign AI-agent control surfaces. - **Rationale:** The automatic lifecycle hook broadly changes AI-agent configuration and instruction directories across multiple vendors. This matches install-hook abuse even though no network exfiltration was found. - **Files touched:** scripts/install-skills.mjs, skills/\*, agents/\*, ~/.claude/skills/\*, ~/.claude/agents/\*, ~/.claude/output-styles/\*, ~/.claude/settings.json, ~/.peaks/config.json, ~/.codex/skills/\*, ~/.cursor/skills/\*, ~/.trae/skills/\* ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package automatically runs its installer after npm installation., The installer defines skill, output-style, and agent directories for multiple unrelated AI tools under the user home directory., The postinstall loops through every configured platform and creates links rather than limiting itself to an explicitly selected tool., The lifecycle entrypoint installs skills, agents, user configuration, and an output-style default. - **Evidence against:** No network or credential-exfiltration behavior was found in the inspected lifecycle code., The manifest does not runtime-depend on peaks-loop itself. ## Affected versions and remediation This report applies to peaks-loop@4.0.44. - Avoid installing peaks-loop@4.0.44. 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.
