A package-controlled skill becomes available to Claude Code and overwrites any existing skill with the same name. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.2.21 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. 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. Installing the package automatically alters the user's Claude Code skill control surface. It removes and replaces a global skill directory without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T12:13:53.658Z - **Finished:** 2026-09-13T12:14:31.401Z - **Download time:** 768 ms - **Static scan time:** 23 ms - **AI review time:** 36951 ms - **Total time:** 37743 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically alters the user's Claude Code skill control surface. It removes and replaces a global skill directory without an explicit setup command. - **Trigger:** npm installation runs the postinstall lifecycle hook; invoking hscrape repeats the copy. - **Impact:** A package-controlled skill becomes available to Claude Code and overwrites any existing skill with the same name. - **Evidence paths:** package.json, lib/install-skill.js, hscrape.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T12:14:31.401Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic deletion and replacement of a personal Claude Code skill directory. - **Attack narrative:** On npm installation, package.json starts lib/install-skill.js. That code resolves the user's home directory, deletes ~/.claude/skills/evo-scraper recursively, and copies package-provided skill instructions there. The hscrape launcher performs the same mutation again on normal CLI use. This is an unconsented postinstall write to a foreign, user-wide AI-agent control surface. - **Rationale:** The package has a concrete, automatic postinstall mutation of a global Claude Code skill directory and forcibly replaces its contents. This meets the install-control-surface blocking policy despite no observed network exfiltration. - **Files touched:** lib/install-skill.js, skill/, ~/.claude/skills/evo-scraper, ~/.claude/skills/evo-scraper/.hscrape-version ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** An automatic postinstall hook runs the skill installer., The installer targets the user's global Claude Code skills directory., It forcibly deletes and replaces the existing evo-scraper skill directory., The CLI repeats the skill installation whenever it is invoked. - **Evidence against:** No network request, credential harvesting, or exfiltration is present in the inspected JavaScript., The copied skill content is bundled locally rather than downloaded at install time. ## Affected versions and remediation This report applies to hscrape@0.2.21. - Avoid installing hscrape@0.2.21. 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.
