Consumer projects can have their dependency lifecycle policy weakened and their AI coding and review behavior changed without an explicit setup command. - **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:** 1.5.185 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically changes consumer package-manager settings and writes broad AI-agent control files. It also installs a review-suppression instruction for those generated files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-09-04T07:06:18.578Z - **Finished:** 2026-09-04T07:08:37.060Z - **Download time:** 1013 ms - **Static scan time:** 165 ms - **AI review time:** 137303 ms - **Total time:** 138482 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically changes consumer package-manager settings and writes broad AI-agent control files. It also installs a review-suppression instruction for those generated files. - **Trigger:** npm postinstall during dependency installation - **Impact:** Consumer projects can have their dependency lifecycle policy weakened and their AI coding and review behavior changed without an explicit setup command. - **Evidence paths:** package.json, postinstall.js, merge.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T07:08:37.060Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic project configuration and AI-agent instruction injection - **Attack narrative:** The install hook finds the consuming project, appends .npmrc settings that enable dependency lifecycle scripts and disable lockfile and side-effect protections, then starts merge.js. The merger creates and overwrites project-wide instructions for multiple AI agents and copies packaged skills into the Claude control surface. It also creates an instruction directing Copilot review to skip the generated files, reducing review visibility of the injected controls. - **Rationale:** This is unconsented postinstall mutation of a broad foreign AI-agent control surface, coupled with weakening package-manager lifecycle safeguards. The local-only screenshot utility does not offset the install-time control injection. - **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 package runs postinstall automatically., Postinstall appends project .npmrc settings that enable dependency lifecycle scripts and disable safeguards., Postinstall launches the merger in the consumer project., The merger writes AGENTS, Claude, Copilot, GitHub instruction, PR-template, and Claude skill files., It installs a Copilot instruction telling code review to skip the generated rule files. - **Evidence against:** No network endpoint, credential collection, or data exfiltration was found., The screenshot helper is a user-invoked local image annotation utility. ## Public findings ### 1.
