Existing same-named skills can be overwritten. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 96.0% - **Started:** 2026-08-19T02:04:30.251Z - **Finished:** 2026-08-19T02:05:41.555Z - **Download time:** 506 ms - **Static scan time:** 2735 ms - **AI review time:** 68062 ms - **Total time:** 71304 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall runs a skill copier that writes bundled agent instructions to the global Claude Code skills directory. Existing same-named skills can be overwritten. - **Trigger:** npm install, including global installation, unless EMDEE\_SKIP\_POSTINSTALL=1 is set - **Impact:** Unconsented mutation of a behavior-bearing AI-agent instruction surface. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/cli/skills-install.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-19T02:05:41.555Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic global Claude Code skill installation - **Rationale:** The package has a concrete unconsented postinstall write into a global AI-agent control surface. It is a first-party bundled skill setup rather than a confirmed payload or exfiltration chain, so it warrants a warning rather than a block. - **Files touched:** scripts/postinstall.mjs, dist/cli/skills-install.js, skills/\*.md, skills/emdee-conventions/\*\*, ~/.claude/skills/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall unconditionally launches the bundled skills installer unless an opt-out env var is set., The installer defaults to the global Claude Code skills directory and overwrites bundled Markdown skill files recursively., This changes a behavior-bearing AI-agent instruction surface during npm installation without an explicit setup command. - **Evidence against:** The install hook only executes the packaged installer; no lifecycle network call, credential read, or remote payload loading was found., OAuth network requests and credential storage are reachable through explicit login/remote CLI actions, not postinstall. ## Public findings ### 1.
