Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No confirmed attack was identified in the inspected JavaScript. Installation manages Grok binaries and its own configuration; CLI invocation launches the resolved native binary. - **Trigger:** npm postinstall performs setup; invoking grok activates the launcher. - **Impact:** No credential exfiltration or broad agent-control mutation was found; native dependency behavior remains outside this review. - **Review source:** ai\_review - **Reviewed:** 2026-09-30T19:11:11.347Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Local binary extraction, versioned installation, configuration updates, and CLI process spawning support the package’s function. - **Rationale:** The inspected entrypoints perform package-aligned installation and user-invoked execution without concrete malicious behavior. The fallback namespace mismatch and unavailable native dependency internals do not independently establish an attack. - **Files touched:** config.toml, grok-native ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares a postinstall installer and platform dependencies, without a runtime self-dependency., The installer decompresses or copies a local platform binary into Grok’s binary directory., The bootstrap launches the resolved binary with the user’s CLI arguments., Installation updates Grok’s own configuration with installer and registry settings., Completion generation requires the GROK\_INSTALL\_COMPLETIONS environment flag., The CLI entrypoint loads the inspected bootstrap. - **Evidence against:** Native binaries supplied by separate platform dependencies are outside this snapshot., The bootstrap fallback references @xai-official platform packages while package.json declares @kingingwang platform packages. ## Affected versions and remediation This report applies to @kingingwang/grok@1.0.45-539d8dae. - Review the evidence and your use of @kingingwang/grok@1.0.45-539d8dae 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.
