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. I found no concrete malware behavior, but marketplace activation automatically sends Luckiest skill usage with persistent hashed identifiers and no separate telemetry opt-in. The installer’s separate CLI hook registration is consent-gated, which does not gate the marketplace hook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-16T22:48:42.322Z - **Finished:** 2026-10-16T22:50:07.281Z - **Download time:** 2317 ms - **Static scan time:** 877 ms - **AI review time:** 81764 ms - **Total time:** 84959 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:** The marketplace plugin automatically registers a skill usage telemetry hook. When a Luckiest skill runs, the hook sends skill metadata with stable hashed installation and session identifiers. - **Trigger:** A user runs a Luckiest skill through the marketplace plugin. - **Impact:** Luckiest can associate reports across skill runs using persistent hashed identifiers; the inspected payload does not include prompts or tool output. Marketplace telemetry has no separate opt-in in the inspected source. - **Evidence paths:** hooks/hooks.json, hooks/report-skill-usage.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-16T22:50:07.281Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The PostToolUse hook posts the skill slug, plugin version, and hashed identifiers to the Luckiest API. - **Rationale:** I found no concrete malware behavior, but marketplace activation automatically sends Luckiest skill usage with persistent hashed identifiers and no separate telemetry opt-in. The installer’s separate CLI hook registration is consent-gated, which does not gate the marketplace hook. - **Files touched:** hooks/hooks.json, hooks/report-skill-usage.mjs - **Network endpoints:** https://api.luckiest.co/api/skills/telemetry ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The plugin manifest runs a PostToolUse hook for Skill events., The hook reports Luckiest skill usage to api.luckiest.co and includes a stable install hash and a session hash., The hook derives the install hash from the machine hostname and home directory, creating a linkable identifier across runs., The CLI installer requires an explicit prompt or --hook flag to register its usage hook; marketplace activation does not use that installer prompt., The package lifecycle script runs only a version check; flagged subprocesses belong to task-specific graph rendering or video QA helpers. - **Evidence against:** The telemetry is limited to Luckiest skill metadata; source says it does not send prompt text or tool output and ignores foreign skills., The telemetry destination is the package-aligned Luckiest API, and the marketplace plugin does not mutate consumer settings through bin/install.js., The video QA helper invokes npx only when explicitly run and the Hyperframes command is missing; the graph renderer pipes graph data to Graphviz. ## Affected versions and remediation This report applies to luckiest-co@1.0.49. - Review the evidence and your use of luckiest-co@1.0.49 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.
