The package can change the behavior and available prompts of installed AI coding tools and alter a detected project without an explicit setup command. - **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:** 4.0.41 - **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 alters global AI-agent extension locations for multiple vendors and may auto-upgrade a detected project. This is an unconsented broad AI-agent control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-11T16:00:51.697Z - **Finished:** 2026-09-11T16:02:12.587Z - **Download time:** 1011 ms - **Static scan time:** 8622 ms - **AI review time:** 71255 ms - **Total time:** 80890 ms The recorded confidence comes from the underlying analysis.

This is an unconsented broad AI-agent control-surface mutation. - **Trigger:** Installing peaks-loop through npm runs postinstall. - **Impact:** The package can change the behavior and available prompts of installed AI coding tools and alter a detected project without an explicit setup command. - **Evidence paths:** package.json, scripts/install-skills.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T16:02:12.587Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Cross-platform agent skill, style, and agent-file installation plus automatic upgrade dispatch. - **Attack narrative:** On npm installation, package.json launches scripts/install-skills.mjs. The script enumerates multiple AI-agent vendor directories and installs bundled skills across all configured platforms, including Codex, Claude, Trae, and Cursor. It also installs agents and can set a Claude output style. If it detects an older Peaks project, it invokes peaks upgrade automatically. These install-time changes affect broad, foreign AI-agent control surfaces without requiring a user-run setup command. - **Rationale:** The automatic postinstall fan-out mutates several home-directory AI-agent extension and configuration surfaces and may run a project upgrade. This concrete install-time behavior meets the blocking policy for unconsented broad AI-agent control-surface mutation. - **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:** The package automatically runs its installer at npm postinstall., The installer targets home-directory skills, output styles, and agents for multiple AI tools, including Codex, Claude, Trae, and Cursor., Postinstall fans out bundled skills across every configured platform instead of limiting itself to a detected tool., Postinstall can invoke an automatic project upgrade command. - **Evidence against:** No credential harvesting or network exfiltration was established from the inspected lifecycle source., No runtime dependency on peaks-loop itself appears in package.json. ## Affected versions and remediation This report applies to peaks-loop@4.0.41. - Avoid installing peaks-loop@4.0.41. 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.
