The package automatically changes agent behavior and routing in the consuming 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:** 0.1.6 - **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 active postinstall hook writes package-controlled behavior into foreign agent instruction files without an affirmative consent gate. This is an unconsented install-time AI-agent control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-18T11:24:07.952Z - **Finished:** 2026-10-18T11:24:52.856Z - **Download time:** 774 ms - **Static scan time:** 56 ms - **AI review time:** 44073 ms - **Total time:** 44904 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 the consumer project's agent instruction files without affirmative consent. It inserts package instructions that influence how the agent handles requests. - **Trigger:** A local npm installation runs the postinstall hook. - **Impact:** The package automatically changes agent behavior and routing in the consuming project. - **Evidence paths:** package.json, scripts/init.mjs, instructions/AGENTS.md - **Review source:** ai\_review - **Reviewed:** 2026-10-18T11:24:52.856Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook resolves the consumer project root, then updates or creates AGENTS.md and CLAUDE.md with package-provided pointers and removes a matching legacy instruction. - **Attack narrative:** During local installation, postinstall updates the consumer's root AGENTS.md and CLAUDE.md without asking first. Those files receive package-controlled agent instructions, which alter request routing and skill loading. - **Rationale:** The active postinstall hook writes package-controlled behavior into foreign agent instruction files without an affirmative consent gate. This is an unconsented install-time AI-agent control-surface mutation. - **Files touched:** AGENTS.md, CLAUDE.md, .atlas/config.json, .atlas/README.md ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs scripts/init.mjs from postinstall., The local postinstall path resolves the consumer project root and calls applyPointers without an affirmative consent check., applyPointers edits root AGENTS.md and CLAUDE.md, removing a legacy instruction and adding package instructions., The upsert routine writes the resulting content to those files., The injected AGENTS.md instructions direct how the agent routes requests and loads skills. - **Evidence against:** The installer skips global installs. ## Affected versions and remediation This report applies to ux-atlas@0.1.6. - Avoid installing ux-atlas@0.1.6. 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.
