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 in the inspected JavaScript. The lifecycle script performs package-aligned local binary installation and configuration. - **Trigger:** npm installation runs postinstall; invoking the grok command runs the resolved local binary. - **Impact:** No credential collection, network transmission, remote payload retrieval, or broad control-surface mutation was found in the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-09-21T10:49:49.340Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The scripts resolve platform optional dependencies, extract or link their binary, and launch it only through the CLI entrypoint. - **Rationale:** The source has an install hook, but its visible behavior is local CLI binary setup and config persistence. No concrete malicious behavior was established from the package source. - **Files touched:** bin/grok, bin/grok-native, ~/.grok/bin, ~/.grok/config.toml ### Review decision - **Verdict:** Clean - **Confidence:** 82.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** The manifest's only lifecycle hook runs the local postinstall script., The postinstall script resolves a matching platform optional dependency and installs its grok binary locally., The bootstrap launcher only spawns the resolved binary with caller-supplied arguments and inherited standard I/O. - **Evidence against:** Postinstall writes a config file under GROK\_HOME and can invoke npm config to retain a registry setting., The package installs a native binary from an optional platform package, whose contents are not present in this snapshot. ## Affected versions and remediation This report applies to @kingingwang/grok@1.0.38-3662b885. - Review the evidence and your use of @kingingwang/grok@1.0.38-3662b885 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.
