Install-time code writes a bundled Claude Code skill into a package-specific user skill directory and replaces it on package-version changes. No confirmed credential theft, network exfiltration, or remote payload execution is present in the inspected JavaScript. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-16T15:12:57.126Z - **Finished:** 2026-08-16T15:13:37.732Z - **Download time:** 509 ms - **Static scan time:** 30 ms - **AI review time:** 40066 ms - **Total time:** 40606 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code writes a bundled Claude Code skill into a package-specific user skill directory and replaces it on package-version changes. No confirmed credential theft, network exfiltration, or remote payload execution is present in the inspected JavaScript. - **Trigger:** npm postinstall or a user running \`hscrape\` - **Impact:** Changes the local agent's available instructions and can discard local edits to that specific skill on upgrade. - **Evidence paths:** package.json, hscrape.js, lib/install-skill.js, skill/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-16T15:13:37.732Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** recursive replacement of a first-party Claude Code skill - **Rationale:** This is a real postinstall mutation of an AI-agent extension, limited to the package's own named skill directory. It warrants a warning under the lifecycle-risk policy, not a block, because no concrete malicious chain was found. - **Files touched:** lib/install-skill.js, skill/, ~/.claude/skills/evo-scraper, ~/.claude/skills/evo-scraper/.hscrape-version ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** \`postinstall\` runs the skill installer., Installer recursively deletes and replaces \`~/.claude/skills/evo-scraper\` on version change., The same installer is invoked whenever the \`hscrape\` command runs., Bundled skill instructs Claude Code to operate the CLI and external scraper service. - **Evidence against:** The write target is a package-specific Claude skill directory, not a broad Claude configuration path., No JavaScript network client, credential harvesting, or exfiltration behavior was found., The launcher only resolves and executes the declared platform binary; it does not download or evaluate a payload. ## Public findings ### 1.

L51: fs.rmSync(dest, { recursive: true, force: true }); L52: fs.mkdirSync(dest, { recursive: true }); L53: fs.cpSync(src, dest, { recursive: true }); // requires Node >= 16.7 L54: fs.writeFileSync(stamp, version); L55: } ``` ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8.
