Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 13 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.4.16 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall does create user-level login persistence, but the README clearly describes this behavior and it directly supports the package's sync-daemon purpose. Network syncing requires browser sign-in and is limited to skills selected through the dashboard. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-01T04:56:06.347Z - **Finished:** 2026-11-01T04:57:03.875Z - **Download time:** 1030 ms - **Static scan time:** 527 ms - **AI review time:** 55970 ms - **Total time:** 57528 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 identified; the package installs a disclosed login daemon for its skill-sync service. - **Trigger:** Package installation runs postinstall; the daemon connects after a user signs in. - **Impact:** The daemon persists across logins and can sync selected skill files to the configured service as described by the package. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T04:57:03.875Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer registers the package's daemon with the platform's user-session service. The daemon syncs dashboard-selected skills using the user's machine token. - **Rationale:** The postinstall does create user-level login persistence, but the README clearly describes this behavior and it directly supports the package's sync-daemon purpose. Network syncing requires browser sign-in and is limited to skills selected through the dashboard. - **Files touched:** ~/.jive/daemons, ~/.jive/logs, ~/Library/LaunchAgents, $XDG\_CONFIG\_HOME/systemd/user, ~/.jive/skill-sync-token.json, detected skills folders - **Network endpoints:** https://skill-sync.jive.sh ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall script repairs the package's CLI targets and registers its own sync daemon., The README discloses that the daemon starts at login after installation and upgrades through the package manager., Sync requires a token supplied through browser sign-in, and only skills selected on the dashboard are synced., The default service endpoint is https://skill-sync.jive.sh, and requests send the signed-in machine token to the configured endpoint., The sync code documents that unselected skills are never pushed, overwritten or deleted. ## Affected versions and remediation This report applies to @jive-sh/skill-sync@0.4.16. - Review the evidence and your use of @jive-sh/skill-sync@0.4.16 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.
