Installation invokes a skills copier that writes EMDEE Markdown skills into Claude Code's global skills directory. No confirmed install-time exfiltration or payload execution was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 94.0% - **Started:** 2026-08-15T09:31:25.950Z - **Finished:** 2026-08-15T09:32:28.005Z - **Download time:** 1013 ms - **Static scan time:** 2741 ms - **AI review time:** 58300 ms - **Total time:** 62055 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation invokes a skills copier that writes EMDEE Markdown skills into Claude Code's global skills directory. No confirmed install-time exfiltration or payload execution was found. - **Trigger:** npm postinstall - **Impact:** Existing EMDEE-named Claude skills can be replaced and become available to Claude Code without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/cli/skills-install.ts, src/cli/auth.ts, src/cli/remote-client.ts, bin/emdee.js - **Review source:** ai\_review - **Reviewed:** 2026-08-15T09:32:28.005Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic global Claude Code skill installation - **Rationale:** Source confirms an unprompted postinstall write into Claude Code's global skills directory. The reviewed lifecycle path contains no network, credential, or arbitrary payload behavior, so this is a warn-level agent-extension lifecycle risk rather than malware. - **Files touched:** scripts/postinstall.mjs, dist/cli/skills-install.js, skills/emdee-describe-asset.md, skills/emdee-describe-image.md, skills/emdee-onboarder.md, skills/emdee-summariser.md, ~/.claude/skills/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall runs a bundled skills installer., Installer defaults to ~/.claude/skills and overwrites packaged Markdown skills., The install-time write targets Claude Code's global skill directory without an install prompt. - **Evidence against:** The copied content is limited to package-local .md skill files., No install-time network request, credential read, shell payload, or arbitrary-code loader was found., OAuth/network operations are user-invoked login and remote CLI paths. ## Public findings ### 1.
