The package can automatically influence Copilot and other agent instruction surfaces in every installing project. - **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:** 1.5.245 - **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. An automatic install hook mutates consumer-project settings and initializes AI-agent rule files. This is an unconsented broad AI-agent control-surface write. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-29T02:11:34.146Z - **Finished:** 2026-09-29T02:12:36.885Z - **Download time:** 505 ms - **Static scan time:** 219 ms - **AI review time:** 62014 ms - **Total time:** 62739 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** An automatic install hook mutates consumer-project settings and initializes AI-agent rule files. This is an unconsented broad AI-agent control-surface write. - **Trigger:** Installing the package runs its postinstall lifecycle hook. - **Impact:** The package can automatically influence Copilot and other agent instruction surfaces in every installing project. - **Evidence paths:** package.json, postinstall.js, merge.js - **Review source:** ai\_review - **Reviewed:** 2026-09-29T02:12:36.885Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook edits .npmrc to enable dependency lifecycle scripts and disable cache behavior, then starts the merger in the consumer project to create agent instruction content. - **Attack narrative:** On installation, the package executes postinstall.js without a user command. That hook changes the consumer project's pnpm configuration to keep dependency lifecycle scripts active and caching disabled, then runs its rule-merging initializer in the consumer project. The merger builds Copilot instruction content from package-controlled rules and project-private content. This automatically changes broad AI-agent control surfaces during dependency installation. - **Rationale:** The automatic lifecycle hook modifies consumer configuration and writes agent-control content without an explicit setup command. This meets the policy for blocking unconsented postinstall mutation of a broad AI-agent control surface. - **Files touched:** package.json, postinstall.js, merge.js ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs postinstall.js automatically after installation., The install hook changes the consumer project's pnpm lifecycle and caching settings., The install hook launches merge.js init in the consumer project., The launched merger creates Copilot instruction content from package rules and project-private rules. - **Evidence against:** No credential collection, external network recipient, or remote code-loading behavior was identified in the inspected paths. ## Affected versions and remediation This report applies to @routerhub/agent-rules@1.5.245. - Avoid installing @routerhub/agent-rules@1.5.245. 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.
