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. npm postinstall runs a skills copier that writes package markdown into Claude Code's user-global skills directory. That directory is a foreign agent control surface and is mutated without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-09-18T21:18:26.821Z - **Finished:** 2026-09-18T21:20:53.977Z - **Download time:** 1030 ms - **Static scan time:** 2216 ms - **AI review time:** 143909 ms - **Total time:** 147156 ms The recorded confidence comes from the underlying analysis.

That directory is a foreign agent control surface and is mutated without an explicit user command. - **Trigger:** npm install of this package, including a global or dependency install, unless EMDEE\_SKIP\_POSTINSTALL=1. - **Impact:** Claude Code can load package-authored skills in later sessions, including overwriting existing skill files in that global directory. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/cli/skills-install.ts, dist/cli/skills-install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-18T21:20:53.977Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall spawn of skills-install copying markdown into ~/.claude/skills - **Attack narrative:** On npm install, postinstall runs dist/cli/skills-install.js unless EMDEE\_SKIP\_POSTINSTALL=1. That copier writes packaged skill markdown into ~/.claude/skills and overwrites files already there. Claude Code loads those files as agent instructions, so any install of this package, including as a dependency, injects package-authored behavior into a foreign agent without an explicit skills-install or plugin-install command. An environment opt-out is not install-time consent. - **Rationale:** The published postinstall hook copies skill files into ~/.claude/skills, Claude Code's user-global agent control surface, without an explicit user command. That is unconsented install-time mutation of a foreign AI-agent control surface and should be blocked. - **Files touched:** scripts/postinstall.mjs, dist/cli/skills-install.js, ~/.claude/skills/ ### Review decision - **Verdict:** Malicious - **Confidence:** 92.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json postinstall runs scripts/postinstall.mjs on every npm install, not only an explicit plugin or skills command., postinstall auto-spawns dist/cli/skills-install.js unless EMDEE\_SKIP\_POSTINSTALL=1, and treats a failed copy as a warning so install still succeeds., skills-install copies packaged markdown skills into the user-global ~/.claude/skills directory and overwrites files already there., The installer tells the user to restart Claude Code so those files load as agent instructions without a separate consented setup step. - **Evidence against:** Auth code is PKCE OAuth to emdee.tech with tokens stored under ~/.config/emdee, not a hidden credential drain., spawn plus a loopback HTTP server in auth-commands is a browser login callback, not a reverse shell., No eval, no runtime self-dependency on another release, and no install-time network exfil were found., Skill markdown is product onboarding and vault conventions; an opt-out env var exists but is not install-time consent. ## Affected versions and remediation This report applies to @aisystemresources/emdee@0.21.1. - Avoid installing @aisystemresources/emdee@0.21.1. 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.
