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 hook does send default-on install telemetry, but the inspected code limits the event data and sends it to the package's product analytics endpoint. The flagged agent configuration behavior is reached through explicit CLI initialization, not the install hook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-15T14:44:26.982Z - **Finished:** 2026-10-15T14:45:59.618Z - **Download time:** 780 ms - **Static scan time:** 2107 ms - **AI review time:** 89747 ms - **Total time:** 92636 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 surface was identified. Postinstall sends a limited install analytics event to the package's analytics endpoint. - **Trigger:** npm install triggers the postinstall hook; Claude configuration setup requires the CLI init flow. - **Impact:** The event supports install counting. No credential transfer, unconsented agent configuration mutation, or other concrete attack behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-15T14:45:59.618Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook records an install event and starts a telemetry flush. The inspected payload uses an install identifier and bounded metadata; agent configuration writes occur in the explicit init path. - **Rationale:** The postinstall hook does send default-on install telemetry, but the inspected code limits the event data and sends it to the package's product analytics endpoint. The flagged agent configuration behavior is reached through explicit CLI initialization, not the install hook. - **Network endpoints:** https://events.nanonets.com/batch/ ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** package.json runs a postinstall hook; that hook records and flushes an install event, while Claude setup is reached through the CLI init command., The install event is limited to its event name and global-install flag, with common version and platform metadata and a random install identifier; it is sent to the configured product analytics endpoint., Claude configuration setup is performed by runInit and is called from the CLI init flow., The other flagged locations describe repo housekeeping, existing Trail wiring detection, agent-file filtering, and bounded Git checkout behavior. - **Evidence against:** Postinstall telemetry is automatic and detached; telemetry defaults on unless a gate or user setting disables it., Explicit init can write agent configuration and a skill to repo or user locations. ## Affected versions and remediation This report applies to @trailhq/trail-code@0.23.0. - Review the evidence and your use of @trailhq/trail-code@0.23.0 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.
