Network activity is gated on caller-supplied configuration and authentication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-26T00:11:17.556Z - **Finished:** 2026-09-26T00:13:48.057Z - **Download time:** 1267 ms - **Static scan time:** 5049 ms - **AI review time:** 144185 ms - **Total time:** 150501 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:** No confirmed attack surface was identified. The package is a configured private monitoring runner. - **Trigger:** A user runs the package command with required configuration. - **Impact:** No unconsented installation-time action, persistence, or confirmed credential exfiltration was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-26T00:13:48.057Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It requires a cloud URL and authentication token before it can poll for monitor work. - **Rationale:** Static inspection found no lifecycle hook and no concrete malicious behavior. Network activity is gated on caller-supplied configuration and authentication. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package metadata exposes only the bundled command and main entrypoint, with no lifecycle scripts., The runner requires a caller-provided cloud URL and an agent or runtime token before polling for monitor work. ## Affected versions and remediation This report applies to @testsmith/api-spector-agent@0.4.9. - Review the evidence and your use of @testsmith/api-spector-agent@0.4.9 before allowing it.
