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 automatically sends install telemetry to its vendor and includes identifying Git configuration such as display name and email. Under the review rules, default install-time telemetry is suspicious even when it has an opt-out. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-11-01T08:25:54.318Z - **Finished:** 2026-11-01T08:26:26.452Z - **Download time:** 269 ms - **Static scan time:** 276 ms - **AI review time:** 31587 ms - **Total time:** 32134 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:** Default install-time telemetry sends identifying Git configuration to the vendor service. - **Trigger:** Package installation invokes the postinstall hook without an explicit user request. - **Impact:** The vendor receives identifying details such as the configured Git display name and email during installation. - **Evidence paths:** package.json, install/postinstall.cjs, install/collector.cjs, install/git-context.cjs, install/identity.cjs, install/bridge.cjs - **Review source:** ai\_review - **Reviewed:** 2026-11-01T08:26:26.452Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The collector reads Git configuration, adds identity fields to an install event, and posts it to the vendor endpoint. Telemetry can be disabled with listed environment variables. - **Rationale:** The package automatically sends install telemetry to its vendor and includes identifying Git configuration such as display name and email. Under the review rules, default install-time telemetry is suspicious even when it has an opt-out. - **Files touched:** ~/.threadplane/installation-id, .install-collector/development-install.mjs - **Network endpoints:** https://threadplane.ai/api/growth/collect/v1/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 97.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs install/postinstall.cjs automatically from its postinstall hook., The postinstall hook runs the collector during package installation., The collector sends install events to https://threadplane.ai/api/growth/collect/v1/install., The event includes package, platform, runtime, package-manager and consumer-context details, plus an installation identity., The collector discovers Git configuration and attaches the resulting identity to the event., Git identity collection includes the configured display name and email address. - **Evidence against:** The destination is the package vendor's own service, and the collector does not follow redirects., The inspected install collector does not read or transmit service credentials or file contents. ## Affected versions and remediation This report applies to @threadplane/langgraph@0.3.4. - Review the evidence and your use of @threadplane/langgraph@0.3.4 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.
