Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected installer performs product-aligned daemon registration, but its postinstall path selects a platform-specific self-alias package whose binary source was unavailable. That unresolved executable prevents a clean verdict; the inspected evidence does not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-25T19:13:41.624Z - **Finished:** 2026-10-25T19:14:45.371Z - **Download time:** 1031 ms - **Static scan time:** 450 ms - **AI review time:** 62266 ms - **Total time:** 63747 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 attack was established in the inspected JavaScript source, but the postinstall path registers and starts a platform binary whose source was unavailable. - **Trigger:** Installing the package runs its postinstall hook; the registered daemon starts at user login. - **Impact:** The unresolved binary may run persistently with the user's permissions; its behavior could not be determined from this snapshot. - **Evidence paths:** package.json, install.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-25T19:14:45.371Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer selects a platform package, links its binary into command targets, and registers that executable with the platform service manager. - **Rationale:** The inspected installer performs product-aligned daemon registration, but its postinstall path selects a platform-specific self-alias package whose binary source was unavailable. That unresolved executable prevents a clean verdict; the inspected evidence does not establish malicious behavior. - **Files touched:** package.json, install.cjs ### Review decision - **Verdict:** Manual Review - **Confidence:** 78.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The postinstall hook runs install.cjs, and the manifest declares platform-specific optional aliases to other releases of the same package., The installer links the selected platform package's binary into the command targets and registers a daemon to start at login., The installer invokes daemon registration during postinstall; the registered launch agent is configured to run at login and restart after failure., The platform binaries selected by those aliases were not available for source inspection, so their behavior remains unresolved. - **Evidence against:** The CLI source describes user-selected skill syncing and passkey login; it does not establish malicious behavior by the unresolved binaries. ## Affected versions and remediation This report applies to @jive-sh/skill-sync@0.4.4. - Review the evidence and your use of @jive-sh/skill-sync@0.4.4 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.
