A dependency can persist package-authored instructions and skills across Claude, Copilot, and AGENTS-compatible tooling while weakening review visibility. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.5.182 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically alters the consumer project's package-manager settings and AI-agent control files. It also copies package-controlled skills into the project and suppresses review of its generated files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-09-04T02:11:12.282Z - **Finished:** 2026-09-04T02:12:10.818Z - **Download time:** 1012 ms - **Static scan time:** 143 ms - **AI review time:** 57381 ms - **Total time:** 58536 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically alters the consumer project's package-manager settings and AI-agent control files. It also copies package-controlled skills into the project and suppresses review of its generated files. - **Trigger:** npm lifecycle postinstall during package installation. - **Impact:** A dependency can persist package-authored instructions and skills across Claude, Copilot, and AGENTS-compatible tooling while weakening review visibility. - **Evidence paths:** package.json, postinstall.js, merge.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T02:12:10.818Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic project configuration and AI-agent instruction injection. - **Attack narrative:** On installation, postinstall locates the consumer project, appends settings that enable dependency lifecycle scripts and disable pnpm safeguards, then runs merge.js init. That code writes instruction files consumed by several AI coding tools, copies package-supplied skills into .claude/skills, and creates a Copilot instruction directing code review to skip those files. These are unconsented broad control-surface changes initiated by dependency installation. - **Rationale:** The package performs automatic postinstall mutation of the consumer project's package-manager configuration and multiple AI-agent control surfaces. The combined lifecycle hook, broad writes, skill injection, and review-suppression instruction establish malicious install-hook abuse. - **Files touched:** .npmrc, AGENTS.md, CLAUDE.md, AGENTS.private.md, .github/copilot-instructions.md, .github/instructions/\*.instructions.md, .github/PULL\_REQUEST\_TEMPLATE.md, .claude/skills/\* ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs postinstall automatically., The install hook changes the consumer .npmrc to enable dependency lifecycle scripts and disable pnpm safeguards., The install hook automatically runs the merger in the consumer project., The merger writes agent instruction files for Claude, Copilot, and AGENTS-compatible tools., It copies package-supplied skills into the consumer .claude directory., It installs an instruction that tells code review to skip generated agent-rule files. - **Evidence against:** No network endpoints or credential-exfiltration code were found in the inspected lifecycle and merger sources., The screenshot helper is a local image-annotation utility; its child-process use is limited to sips. ## Public findings ### 1.
