This report does not record a matching static-policy override reason. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No confirmed malicious attack surface was established. Network, filesystem, and shell capabilities are invoked only through the package's explicit agent and utility commands. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-04T04:14:29.565Z - **Finished:** 2026-09-04T04:15:48.210Z - **Download time:** 770 ms - **Static scan time:** 6907 ms - **AI review time:** 70967 ms - **Total time:** 78645 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 established. Network, filesystem, and shell capabilities are invoked only through the package's explicit agent and utility commands. - **Trigger:** A user must run the CLI, start the engine, or separately execute a bundled template utility. - **Impact:** No unconsented install-time execution, credential exfiltration, or foreign control-surface mutation was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-04T04:15:48.210Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-configured AI-agent runtime and standalone local utilities. - **Rationale:** Static findings stem from an explicitly operated AI-agent engine and bundled utility templates. Source inspection found no install hook, secret-forwarding endpoint, or automatic malicious execution path. ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Final policy explanation:** The AI recommended clean, but the final policy action is warn. This report does not record a matching static-policy override reason. - **Evidence for AI clean decision:** The manifest exposes a CLI and start command but no automatic install lifecycle hook., The runtime sends model requests only to a configured provider URL, defaulting to Anthropic's API., The explicit init command creates the selected state directory and stores only an API key supplied during that command., Credential-related runtime code defines blocked environment-key patterns rather than forwarding environment contents., A bundled brainstorming template uses a loopback server and an external branding image only when that separate template script is run., The graph-rendering template invokes the fixed local dot executable only when run directly with a supplied skill directory. - **Evidence against:** No preinstall, install, or postinstall script is present., No fixed third-party credential collection endpoint or secret-exfiltration request was found., The apparent credential persistence is local, explicit-init behavior with owner-only file permissions., The scanner-highlighted template scripts are standalone utilities, not package-install execution paths. ## Affected versions and remediation This report applies to engine7@7.1.67. - Review the evidence and your use of engine7@7.1.67 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.
