It changes user-level AI-agent behavior and configuration across multiple products without consent at install time. - **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:** 4.0.39 - **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. The postinstall hook automatically populates and modifies broad AI-agent control directories. It can also set Claude Code's output style without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-11T14:26:00.683Z - **Finished:** 2026-09-11T14:27:03.006Z - **Download time:** 1006 ms - **Static scan time:** 8646 ms - **AI review time:** 52669 ms - **Total time:** 62323 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:** The postinstall hook automatically populates and modifies broad AI-agent control directories. It can also set Claude Code's output style without an explicit setup command. - **Trigger:** npm installation, including automatic postinstall execution. - **Impact:** It changes user-level AI-agent behavior and configuration across multiple products without consent at install time. - **Evidence paths:** package.json, scripts/install-skills.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T14:27:03.006Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Cross-platform AI-agent skill, agent, output-style, and settings installation. - **Attack narrative:** On installation, package.json invokes scripts/install-skills.mjs. That script enumerates home-directory control paths for Claude Code, Codex, Cursor, Trae, and other AI tools, then fans out bundled skills across all profiles. It also installs agent and output-style files and writes a Claude settings value that activates the package output style. This is unconsented postinstall mutation of a broad foreign AI-agent control surface. - **Rationale:** The package performs broad user-level AI-agent configuration and capability installation automatically from postinstall. This meets the install-control-surface blocking policy despite no confirmed exfiltration. - **Files touched:** ~/.claude/skills, ~/.claude/output-styles, ~/.claude/agents, ~/.claude/settings.json, ~/.codex/skills, ~/.codex/output-styles, ~/.codex/agents, ~/.cursor/skills, ~/.trae/skills, ~/.peaks/config.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** Installation automatically runs the skill installer., The installer targets skills, output styles, and agents for several unrelated AI tools under the user home directory., The installer fans out to every configured platform and changes Claude settings to activate its bundled output style. - **Evidence against:** No credential collection or external network request was confirmed in the inspected lifecycle code., The installer contains safeguards intended to avoid overwriting some existing files. ## Affected versions and remediation This report applies to peaks-loop@4.0.39. - Avoid installing peaks-loop@4.0.39. 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.
