Installed skills can affect later Claude Code behavior in the user's environment. - **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:** 0.24.6 - **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. LPM flags this version as an AI-agent control-surface risk. An install-time hook automatically installs package-provided skills into Claude Code's user-wide skills directory. This mutates a foreign AI-agent control surface without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-26T06:16:52.829Z - **Finished:** 2026-09-26T06:17:38.723Z - **Download time:** 1021 ms - **Static scan time:** 2658 ms - **AI review time:** 42214 ms - **Total time:** 45894 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 install-time hook automatically installs package-provided skills into Claude Code's user-wide skills directory. This mutates a foreign AI-agent control surface without an explicit user command. - **Trigger:** npm installation runs the post-install lifecycle hook. - **Impact:** Installed skills can affect later Claude Code behavior in the user's environment. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/cli/skills-install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-26T06:17:38.723Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook launches the bundled skills installer, which selects the user's Claude skills directory by default and copies packaged skill files into it. - **Attack narrative:** Installing the package triggers post-install code. It invokes a bundled installer that copies package-controlled skill files into the user's global Claude Code skills directory, making them available to the agent outside the package's own project scope. - **Rationale:** The package performs an unconsented post-install mutation of a foreign, user-wide AI-agent control surface. This meets the install-control-surface blocking policy. - **Files touched:** ~/.claude/skills ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package declares an automatic post-install hook., That hook runs the packaged skills installer during installation., The installer defaults to the user's Claude skills directory and copies packaged skill files there. ## Affected versions and remediation This report applies to @aisystemresources/emdee@0.24.6. - Avoid installing @aisystemresources/emdee@0.24.6. 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.
