A dependency can persist package-authored instructions, skills, and review exclusions in a project without an explicit user 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:** 1.5.210 - **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. On dependency installation, the package changes consumer-project configuration and installs AI-agent instructions and skills. It also installs a rule that suppresses review of its generated files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T07:23:01.590Z - **Finished:** 2026-09-11T07:24:18.148Z - **Download time:** 251 ms - **Static scan time:** 217 ms - **AI review time:** 76090 ms - **Total time:** 76558 ms The recorded confidence comes from the underlying analysis.

It also installs a rule that suppresses review of its generated files. - **Trigger:** npm install or another package-manager installation that runs postinstall. - **Impact:** A dependency can persist package-authored instructions, skills, and review exclusions in a project without an explicit user command. - **Evidence paths:** package.json, postinstall.js, merge.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T07:24:18.148Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic consumer-project AI-agent control-surface mutation. - **Attack narrative:** Installing the package automatically executes postinstall. That code modifies the consumer .npmrc to enable dependency lifecycle scripts, then runs an initializer in the consumer project. The initializer writes Copilot instruction files, copies skills into .claude/skills, and creates a Copilot instruction that excludes those generated files from review. This is an unconsented install-time mutation of broad AI-agent control surfaces. - **Rationale:** The automatic lifecycle changes consumer package-manager behavior and writes AI-agent instructions, skills, and review exclusions into the project. These actions are concrete control-surface mutation, not merely an explicit setup command. - **Files touched:** .npmrc, .gitignore, AGENTS.private.md, AGENTS.md, CLAUDE.md, .github/copilot-instructions.md, .github/instructions/no-review-docs.instructions.md, .claude/skills/, merge.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs postinstall automatically., Postinstall appends settings to the consumer project's .npmrc, including a setting that enables dependency pre/post scripts., Postinstall launches merge.js init in the consumer project., The initializer writes Copilot instructions and copies packaged skills into the consumer project's Claude control surface., It creates an instruction directing Copilot code review to skip generated rule files. - **Evidence against:** No credential harvesting or external network endpoint was found in the automatic lifecycle code., package.json contains no runtime dependency on this package name. ## Affected versions and remediation This report applies to @routerhub/agent-rules@1.5.210. - Avoid installing @routerhub/agent-rules@1.5.210. 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.
