AI coding tools may consume package-authored instructions in the consumer 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:** 0.1.74 - **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 modifies AI-agent instruction files in the consumer project. It can add package-authored guidance to Claude, Cursor, and Copilot control surfaces. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-16T08:14:33.375Z - **Finished:** 2026-09-16T08:15:09.540Z - **Download time:** 761 ms - **Static scan time:** 618 ms - **AI review time:** 34786 ms - **Total time:** 36165 ms The recorded confidence comes from the underlying analysis.

It can add package-authored guidance to Claude, Cursor, and Copilot control surfaces. - **Trigger:** npm installation executes the postinstall lifecycle hook. - **Impact:** AI coding tools may consume package-authored instructions in the consumer project. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-16T08:15:09.540Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unconsented postinstall writes to consumer AI-agent configuration files. - **Attack narrative:** The package declares a postinstall hook that runs automatically during installation. The hook uses the install working directory as the consumer project root, then appends a reference to CLAUDE.md, creates a Cursor rule, and appends Copilot instructions when the corresponding files or directory exist. These changes alter foreign AI-agent control surfaces without an explicit user command or consent. - **Rationale:** This is concrete, automatic postinstall mutation of multiple foreign AI-agent control surfaces. The absence of exfiltration does not neutralize the unconsented control-surface writes. - **Files touched:** CLAUDE.md, .cursor/rules/lds.mdc, .github/copilot-instructions.md, node\_modules/@lawkit/ui/CLAUDE.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** An automatic postinstall hook runs package code during npm installation., The hook appends a package reference to the consumer project's CLAUDE.md without user action., The hook creates a Cursor rule and appends Copilot instructions in the consumer project when those control surfaces exist. - **Evidence against:** The inspected hook has no network, shell, dynamic-code, credential-harvesting, or self-dependency behavior., The runtime entry is a React UI bundle; the only URL found is an SVG namespace. ## Affected versions and remediation This report applies to @lawkit/ui@0.1.74. - Avoid installing @lawkit/ui@0.1.74. 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.
