Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.6.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The package has no install lifecycle hook and its network authentication is explicitly configured by the caller for the selected endpoint. No concrete malicious behavior was found in the active entrypoint. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-27T19:07:41.007Z - **Finished:** 2026-09-27T19:10:47.373Z - **Download time:** 765 ms - **Static scan time:** 4805 ms - **AI review time:** 180795 ms - **Total time:** 186366 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 malicious attack surface was identified. The command is a configured monitoring runner. - **Trigger:** A user runs the package command with an endpoint and token configured. - **Impact:** No unconsented installation action, persistence, or credential transfer to a package-selected destination was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-27T19:10:47.373Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It polls the caller-configured service and posts monitoring results using the supplied authentication value. - **Rationale:** The package has no install lifecycle hook and its network authentication is explicitly configured by the caller for the selected endpoint. No concrete malicious behavior was found in the active entrypoint. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes the bundled agent as the main and command entrypoint and defines no lifecycle scripts., The agent reads its endpoint and authentication token from caller-provided environment variables, then sends monitoring results to that configured endpoint., Fetched test scripts execute in a restricted VM context with a timeout and without timers. ## Affected versions and remediation This report applies to @testsmith/api-spector-agent@0.6.3. - Review the evidence and your use of @testsmith/api-spector-agent@0.6.3 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.
