Installation automatically installs a bundled Claude Code skill, replacing a fixed package-owned skill directory. No source-level credential collection, exfiltration, remote payload retrieval, or broad agent configuration mutation was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 95.0% - **Started:** 2026-08-19T22:06:17.106Z - **Finished:** 2026-08-19T22:07:04.264Z - **Download time:** 504 ms - **Static scan time:** 26 ms - **AI review time:** 46627 ms - **Total time:** 47158 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically installs a bundled Claude Code skill, replacing a fixed package-owned skill directory. No source-level credential collection, exfiltration, remote payload retrieval, or broad agent configuration mutation was found. - **Trigger:** npm postinstall or invocation of hscrape - **Impact:** Automatic agent-extension installation and overwrite of that one skill directory - **Evidence paths:** package.json, lib/install-skill.js, hscrape.js, skill/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-19T22:07:04.264Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** copies bundled skill into Claude Code's personal skills directory - **Rationale:** No concrete malicious behavior was established. The automatic, destructive replacement of a Claude Code skill warrants a warning as first-party agent-extension lifecycle risk. - **Files touched:** lib/install-skill.js, skill/, ~/.claude/skills/evo-scraper ### Review decision - **Verdict:** Suspicious - **Confidence:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for:** postinstall executes the skill installer., Installer replaces ~/.claude/skills/evo-scraper., CLI invocation re-runs the installer. - **Evidence against:** Write target is one package-named skill directory., Skill content is bundled locally; no network code or endpoint appears., Launcher only resolves a scoped platform dependency and forwards CLI arguments. ## Public findings ### 1.
