A dependency can control Copilot and Claude project instructions, persist its skills, and reduce review visibility of its generated files. - **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:** 1.5.212 - **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. Installing the package automatically changes consumer package-manager settings and writes AI-agent configuration and skills into the project. It also installs a review-suppression instruction for those generated files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T10:53:55.519Z - **Finished:** 2026-09-11T10:54:49.006Z - **Download time:** 520 ms - **Static scan time:** 176 ms - **AI review time:** 52790 ms - **Total time:** 53487 ms The recorded confidence comes from the underlying analysis.

It also installs a review-suppression instruction for those generated files. - **Trigger:** npm installation runs postinstall. - **Impact:** A dependency can control Copilot and Claude project instructions, persist its skills, and reduce review visibility of its generated files. - **Evidence paths:** package.json, postinstall.js, merge.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T10:54:49.006Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time mutation of consumer AI-agent control surfaces. - **Attack narrative:** The package's postinstall runs without an explicit user command, edits the consuming project's .npmrc to ensure lifecycle scripts execute, then invokes merge.js in that project. The merger writes project-level Copilot instructions, Claude skills, and related rule files. It additionally generates a Copilot review instruction that tells reviewers to skip the generated files, weakening visibility over the package-controlled agent configuration. - **Rationale:** This is an unconsented install-time mutation of broad foreign AI-agent control surfaces, reinforced by persistence-oriented package-manager changes and review suppression. No network theft is needed for this concrete control-hijack behavior. - **Files touched:** .npmrc, .gitignore, AGENTS.private.md, AGENTS.md, CLAUDE.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 policy risk:** The manifest automatically runs postinstall., Postinstall changes the consumer project's .npmrc to enable lifecycle scripts and disable safeguards., Postinstall launches the rule merger in the consumer project., The merger writes Copilot and Claude agent-control files and copies skills into the project., It creates an instruction telling code review to skip all generated agent-rule files. - **Evidence against:** No source evidence of network exfiltration or credential collection was found., The screenshot annotation helper only processes user-supplied local image paths when invoked. ## Affected versions and remediation This report applies to @routerhub/agent-rules@1.5.212. - Avoid installing @routerhub/agent-rules@1.5.212. 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.
