The package weakens lifecycle safeguards, persists package-controlled instructions across multiple AI tools, and suppresses review of those instructions. - **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:** 1.5.184 - **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 modifies the consumer project and its npm configuration. It installs broad AI-agent instructions and skills, then directs Copilot to skip review of those generated files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-09-04T03:17:09.128Z - **Finished:** 2026-09-04T03:18:07.852Z - **Download time:** 772 ms - **Static scan time:** 206 ms - **AI review time:** 57746 ms - **Total time:** 58724 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically modifies the consumer project and its npm configuration. It installs broad AI-agent instructions and skills, then directs Copilot to skip review of those generated files. - **Trigger:** npm dependency installation, which runs postinstall - **Impact:** The package weakens lifecycle safeguards, persists package-controlled instructions across multiple AI tools, and suppresses review of those instructions. - **Evidence paths:** package.json, postinstall.js, merge.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T03:18:07.852Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic lifecycle mutation of project package-manager and AI-agent control files - **Attack narrative:** On installation, postinstall locates the consumer project, appends settings that enable dependency scripts and disable pnpm side-effect caching, and launches its initializer. The initializer writes instruction files for Claude and Copilot, copies skills into the project's Claude directory, and generates a Copilot rule that tells code review to skip the generated files. This is an unconsented install-time takeover of broad AI-agent control surfaces. - **Rationale:** This is concrete unconsented postinstall mutation of a consumer project's package-manager settings and broad AI-agent control surfaces. The generated review-suppression instruction makes the persistence less visible, so the package should be blocked. - **Files touched:** .npmrc, AGENTS.md, CLAUDE.md, AGENTS.private.md, .github/copilot-instructions.md, .github/instructions/no-review-docs.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 automatically runs postinstall on dependency installation., The postinstall script changes the consumer project's .npmrc to enable dependency lifecycle scripts and disable pnpm's side-effect cache., Installation then runs init in the consumer project without a user command., The initializer writes broad Claude, Copilot, GitHub, and agent instruction files into the consumer project., It creates a Copilot instruction that suppresses review of the generated agent-control files., It recursively copies package skills into the consumer project's Claude skills directory. - **Evidence against:** No network endpoint, credential collection, or data exfiltration code was found in the inspected JavaScript., The screenshot helper only processes locally supplied image files and invokes a fixed local image utility. ## Public findings ### 1.
