The package can change multiple AI-agent control surfaces and cause its bundled prompts or style to load in later agent sessions. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 4.0.32 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Npm postinstall modifies broad, foreign AI-agent extension directories and Claude settings without an explicit setup command. It also may run an automatic project upgrade command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-08T14:53:47.775Z - **Finished:** 2026-09-08T14:55:05.590Z - **Download time:** 1012 ms - **Static scan time:** 8341 ms - **AI review time:** 68460 ms - **Total time:** 77815 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Npm postinstall modifies broad, foreign AI-agent extension directories and Claude settings without an explicit setup command. It also may run an automatic project upgrade command. - **Trigger:** Installing the package, including npm global installation, runs postinstall. - **Impact:** The package can change multiple AI-agent control surfaces and cause its bundled prompts or style to load in later agent sessions. - **Evidence paths:** package.json, scripts/install-skills.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-08T14:55:05.590Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall fan-out of skills, agents, settings, and an automatic CLI upgrade. - **Attack narrative:** A normal npm installation invokes scripts/install-skills.mjs. That script distributes package-controlled skills and agent files to several AI-agent home directories, changes Claude settings when no output style is set, and may execute a project upgrade command. These changes occur automatically rather than through an explicit user setup command and affect control surfaces beyond the package's own directory. - **Rationale:** The automatic postinstall fan-out mutates broad third-party AI-agent control surfaces, meeting the install-control-surface blocking policy. No exfiltration was found, but it is not needed for this concrete unconsented persistence and control-surface change. - **Files touched:** scripts/install-skills.mjs, agents/karpathy-reviewer.md, ~/.claude/skills, ~/.claude/agents, ~/.claude/settings.json, ~/.codex/skills, ~/.codex/agents, ~/.cursor/skills, ~/.trae/skills ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs the installer after npm installation., The installer targets several unrelated AI-agent homes, including Claude, Codex, Cursor, Trae, and others., Postinstall fans out bundled skills and agent prompts across all configured platforms., Postinstall writes a Claude output-style setting and can invoke an automatic project upgrade command. - **Evidence against:** No network endpoint, credential collection, or exfiltration was found in the inspected install path., The installer has opt-out environment variables and avoids replacing unmanaged agent files. ## Affected versions and remediation This report applies to peaks-loop@4.0.32. - Avoid installing peaks-loop@4.0.32. 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.
