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. This is a self-hosted AI agent CLI. Environment, network, and shell use are the product and run only when a user invokes engine7, not during npm install. Scanner labels for credential theft, unofficial gateways, and foreign-package overwrite did not match the source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-17T01:22:25.941Z - **Finished:** 2026-09-17T01:25:59.138Z - **Download time:** 757 ms - **Static scan time:** 3762 ms - **AI review time:** 208677 ms - **Total time:** 213197 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 is a self-hosted AI agent CLI. Environment, network, and shell use are the product and run only when a user invokes engine7, not during npm install. Scanner labels for credential theft, unofficial gateways, and foreign-package overwrite did not match the source. - **Trigger:** User runs engine7 init, engine7 start, or engine7 service install after installing the package. - **Impact:** No unconsented install-time mutation or third-party credential theft was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-17T01:25:59.138Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked agent setup and runtime - **Rationale:** Scanner flags came from a large agent bundle that talks to official LLM and chat APIs, stores keys the user typed, and can install its own autostart on command. Those primitives are package-aligned and not an install-time attack. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **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:** Manifest publishes dist/main.mjs and the engine7 CLI with only build and start scripts., Engine posts the configured API key to a provider URL that defaults to api.anthropic.com., Main entrypoint loads config and starts the agent when the user launches it., Init CLI stores a prompted provider API key under ~/.engine7-secrets., Generated config uses official DashScope, MiniMax, and Zhipu endpoints., Bundled render-graphs.js runs local Graphviz via execSync. - **Evidence against:** package.json has no preinstall, install, or postinstall hooks, so nothing runs at npm install., Network hosts are official LLM, Feishu, WeChat, GitHub, and Tavily APIs for a self-hosted agent., Key storage, autostart, and engine launch happen only after engine7 init, start, or service install., render-graphs.js only pipes Graphviz DOT to the local dot binary., No env harvest to a third-party sink, no obfuscation, no self-dependency, and no overwrite of a foreign npm package. ## Affected versions and remediation This report applies to engine7@7.1.51. - Review the evidence and your use of engine7@7.1.51 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.
