Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Soft block: AI-agent control surface** — Warn by default; block when configured. The modified instruction files can affect how AI agents behave 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:** 0.1.1 - **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. The package automatically mutates consumer AI-agent instruction files during postinstall without an explicit consent gate. This is a concrete unconsented control-surface change, so the package should be blocked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-11T04:05:34.427Z - **Finished:** 2026-10-11T04:05:53.072Z - **Download time:** 517 ms - **Static scan time:** 21 ms - **AI review time:** 18105 ms - **Total time:** 18645 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:** The postinstall hook changes AI-agent instruction files in the consumer project without an explicit consent gate. - **Trigger:** Installing the package with npm in a local project. - **Impact:** The modified instruction files can affect how AI agents behave in the consumer project. - **Evidence paths:** package.json, scripts/init.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-11T04:05:53.072Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook updates AGENTS.md and CLAUDE.md with pointers to package instructions and skills, and removes matching legacy text. - **Attack narrative:** During installation, the postinstall hook runs the package initializer. It modifies the consumer project's AGENTS.md and CLAUDE.md files by inserting pointers to UX Atlas instructions and skills, and removes a matching legacy instruction line. The source shows no consent check before these changes. - **Rationale:** The package automatically mutates consumer AI-agent instruction files during postinstall without an explicit consent gate. This is a concrete unconsented control-surface change, so the package should be blocked. - **Files touched:** package.json, scripts/init.mjs ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs scripts/init.mjs automatically as a postinstall hook., The installer removes legacy content and writes behavior-bearing pointers into the consumer project's AGENTS.md and CLAUDE.md files., The pointer updater writes the modified file contents to disk., The postinstall path invokes the project-file mutations without a consent check. ## Affected versions and remediation This report applies to ux-atlas@0.1.1. - Avoid installing ux-atlas@0.1.1. 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.
