This occurs automatically during installation and is not restricted to an explicit CLI action. - **Trigger:** Installing the package runs the postinstall lifecycle hook. - **Impact:** Package-controlled instructions become available to Claude Code without an installation-time consent step. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/cli/skills-install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-26T05:41:56.774Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook launches the skills installer, which creates the default Claude skills directory and copies package files into it. - **Attack narrative:** The package declares postinstall, which launches its skills installer automatically. The installer targets the user's Claude skills directory by default, creates it if necessary, and copies package-provided skill files there. The optional environment opt-out does not establish consent because the default installation path mutates a foreign AI-agent control surface before the user invokes any command. - **Rationale:** This is concrete unconsented postinstall mutation of a broad AI-agent control surface. The lifecycle behavior meets the install-hook abuse blocking policy even though no network exfiltration was identified. - **Files touched:** scripts/postinstall.mjs, dist/cli/skills-install.js, ~/.claude/skills ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest registers an automatic postinstall script., The postinstall script automatically runs the packaged skills installer when its output exists., The installer defaults to the user's Claude skills directory and copies packaged skill files into it., The MCP server itself uses a user-selected local documents directory. - **Evidence against:** The CLI also exposes the skills installation as an explicit command, but the lifecycle hook invokes it without that command or consent. ## Affected versions and remediation This report applies to @aisystemresources/emdee@0.24.4. - Avoid installing @aisystemresources/emdee@0.24.4. 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.
