## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 13 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Persistence
- **Selected version:** 0.4.7
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The postinstall hook creates persistent user-session startup behavior, and platform package sources remain unresolved. The inspected JavaScript does not establish a concrete attack, so this warrants a warning rather than a block.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 77.0%
- **Started:** 2026-10-25T22:39:25.328Z

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:** The postinstall hook can create a daemon that starts automatically at user login and start or restart it during installation. This is persistent behavior, though the inspected source presents it as part of the package’s syncing function.

- **Trigger:** Installing the package outside CI and without the repair-only flag.

- **Impact:** The daemon can continue running across logins until it is stopped or its registration is removed.

- **Evidence paths:** package.json, install.cjs, src/daemons/skill-sync-daemon.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-10-25T22:40:36.034Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The installer registers the daemon with the operating system’s user-session startup manager and enables or restarts it.

- **Rationale:** The postinstall hook creates persistent user-session startup behavior, and platform package sources remain unresolved. The inspected JavaScript does not establish a concrete attack, so this warrants a warning rather than a block.

- **Files touched:** package.json, install.cjs, src/daemons/skill-sync-daemon.ts

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 77.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** package.json runs install.cjs automatically after installation and declares platform aliases that resolve to versioned releases of the same package., install.cjs repairs command targets and registers the daemon during installation; on Linux it enables and restarts a user systemd unit., The daemon registration is skipped in CI or when passed a repair-only flag, but otherwise the installer registers its declared daemon., The source describes the daemon as maintaining a connection to the service hub; the CLI provides a logout command that revokes the machine token and stops syncing.

- **Evidence against:** The inspected source describes the daemon’s role as syncing selected skills through the service hub, and provides a logout path to revoke its token., The platform-specific package sources could not be fully resolved in this snapshot, so their executable behavior remains unverified.

## Affected versions and remediation

This report applies to @jive-sh/skill-sync@0.4.7.

- Review the evidence and your use of @jive-sh/skill-sync@0.4.7 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.
