Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package’s stated sync behavior and sign-in flow are consistent with its purpose, and the usage reporting is disclosed. However, it automatically sends account-linked usage and cost information during a signed-in session, with no usage-specific opt-out found, so this merits a telemetry warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-11-01T03:23:20.879Z - **Finished:** 2026-11-01T03:24:18.376Z - **Download time:** 511 ms - **Static scan time:** 499 ms - **AI review time:** 56487 ms - **Total time:** 57497 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:** Disclosed, automatic account-usage reporting during a signed-in session may expose account identifiers and usage or cost patterns without a usage-specific opt-out found in the inspected source. - **Trigger:** The user signs in with \`skill-sync login\`; reporting begins when the daemon connects and repeats while connected. - **Impact:** The service dashboard can associate account identifiers with usage limits and, for some Claude accounts, recent session cost estimates. - **Evidence paths:** src/daemons/skill-sync-daemon.ts, src/internal/usage.ts, src/internal/config.ts, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-01T03:24:18.376Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The daemon reads usage records from local Claude and Codex account files, then sends changed reports over its authenticated WebSocket. - **Rationale:** The package’s stated sync behavior and sign-in flow are consistent with its purpose, and the usage reporting is disclosed. However, it automatically sends account-linked usage and cost information during a signed-in session, with no usage-specific opt-out found, so this merits a telemetry warning. - **Files touched:** ~/.claude.json, ~/.claude-\/.claude.json, ~/.claude-\/projects/\*.jsonl, ~/.codex-\/sessions/, ~/.jive/skill-sync-token.json - **Network endpoints:** wss://skill-sync.jive.sh/daemon, https://skill-sync.jive.sh (default endpoint; configurable) ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** After a user signs in, the daemon reads usage data for every detected Claude and Codex account and sends it over its service connection., Usage reports include account identifiers and usage or cost figures, and are sent when changed and periodically while connected., The README discloses this reporting, but no usage-specific opt-out appears in the inspected source., The daemon’s service connection is gated on an active signed-in session; sign-in is an explicit CLI action. - **Evidence against:** The package documents its postinstall daemon registration and automatic startup as part of the sync service., The README says only selected skills sync, and newly detected folders start with syncing off., The usage reader extracts usage figures from tool-written files; the inspected flow does not send credentials or session contents. ## Affected versions and remediation This report applies to @jive-sh/skill-sync@0.4.13. - Review the evidence and your use of @jive-sh/skill-sync@0.4.13 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.
