Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. This is a first-party agent extension with automatic telemetry and a credential-reading search capability, but there is no unconsented npm lifecycle execution, broad foreign control-surface mutation, or concrete malware chain. It warrants a warning for extension lifecycle and privacy risk. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-08-27T03:03:08.710Z - **Finished:** 2026-08-27T03:04:13.353Z - **Download time:** 505 ms - **Static scan time:** 467 ms - **AI review time:** 63670 ms - **Total time:** 64643 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:** This first-party Claude Code extension installs a PostToolUse hook that reports Luckiest skill-use metadata. Its bundled trends command can read X cookies only when the user invokes that search tool. - **Trigger:** Installing the Claude Code plugin activates the declared hook; running the trends search invokes its credential resolver. - **Impact:** The vendor receives Luckiest skill identifiers, version, session hash, and a stable installation identifier; the trends command can use local X session cookies for X requests. - **Evidence paths:** package.json, bin/install.js, hooks/hooks.json, hooks/report-skill-usage.mjs, skills/luckiest-trends/scripts/lib/vendor/bird-search/bird-search.mjs, skills/luckiest-trends/scripts/lib/vendor/bird-search/lib/cookies.js - **Review source:** ai\_review - **Reviewed:** 2026-08-27T03:04:13.353Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Claude hook telemetry and user-invoked X cookie-backed search - **Rationale:** This is a first-party agent extension with automatic telemetry and a credential-reading search capability, but there is no unconsented npm lifecycle execution, broad foreign control-surface mutation, or concrete malware chain. It warrants a warning for extension lifecycle and privacy risk. - **Files touched:** hooks/hooks.json, hooks/report-skill-usage.mjs, ~/.luckiest/key, browser cookie stores - **Network endpoints:** https://api.luckiest.co, https://x.com/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The Claude Code plugin registers a command hook for every Skill tool event., The hook derives a stable installation hash from the hostname and home directory when no key exists., The hook sends telemetry to the package vendor's API after matching only Luckiest skill names., The bundled trends tool can retrieve X authentication cookies when the user runs its search command. - **Evidence against:** package.json has no preinstall, install, or postinstall script., The npm installer is user-invoked and asks before adding its settings hook; noninteractive installs decline by default., The hook ignores non-Luckiest skills and sends metadata rather than prompts or tool output., The cookie-using client is documented and implemented as search-only for X. ## Affected versions and remediation This report applies to luckiest-co@1.0.12. - Review the evidence and your use of luckiest-co@1.0.12 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
