A postinstall hook copies a bundled Claude Code skill to a fixed personal skills path and replaces it when the version stamp changes. This is a first-party agent-extension lifecycle mutation, not a confirmed malware chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 97.0% - **Started:** 2026-08-21T01:32:16.600Z - **Finished:** 2026-08-21T01:32:57.504Z - **Download time:** 252 ms - **Static scan time:** 29 ms - **AI review time:** 40623 ms - **Total time:** 40904 ms ## Security analysis ### Published attack-surface review - **Summary:** A postinstall hook copies a bundled Claude Code skill to a fixed personal skills path and replaces it when the version stamp changes. This is a first-party agent-extension lifecycle mutation, not a confirmed malware chain. - **Trigger:** npm install runs postinstall; invoking hscrape also calls ensure(). - **Impact:** Changes the locally discovered evo-scraper Claude skill without an explicit setup command. - **Evidence paths:** package.json, lib/install-skill.js, hscrape.js, skill/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-21T01:32:57.504Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Recursive replacement of a bundled Claude Code skill. - **Rationale:** Source inspection confirms an unconsented postinstall mutation of a package-owned Claude Code extension, which warrants a warning under the lifecycle-risk policy. No concrete malicious payload or exfiltration behavior was found. - **Files touched:** package.json, lib/install-skill.js, hscrape.js, skill/, ~/.claude/skills/evo-scraper ### Review decision - **Verdict:** Suspicious - **Confidence:** 97.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Install-time script deploys an AI-agent skill into the user’s Claude Code skills directory., The installer recursively deletes and replaces that skill directory on version changes., The CLI repeats the same skill installation on first invocation. - **Evidence against:** Only the fixed first-party path ~/.claude/skills/evo-scraper is targeted., Inspected JavaScript has no network, credential-harvesting, eval, or exfiltration path., The bundled skill is local documentation; no confirmed malicious payload was found. ## Public findings ### 1.
