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 suspicious indicators resolve to ordinary CLI behavior: Tonbo credentials go to Tonbo’s API, the foreign-looking key strings are explicitly fake test fixtures, and the installer command is only shown as a manual update suggestion. No install hook or concealed automatic credential forwarding was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-11-03T09:35:21.263Z - **Finished:** 2026-11-03T09:35:59.768Z - **Download time:** 510 ms - **Static scan time:** 1837 ms - **AI review time:** 36157 ms - **Total time:** 38505 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 was identified. The package implements a Tonbo CLI for capturing and managing agent sessions. - **Trigger:** The CLI runs when invoked; account operations and session capture follow user commands or configured hooks. - **Impact:** No unauthorized credential forwarding, hidden execution, or other malicious impact was found. - **Review source:** ai\_review - **Reviewed:** 2026-11-03T09:35:59.768Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It sends service requests to Tonbo endpoints using Tonbo credentials. The reported third-party credential strings are fake filter test data, and the upgrade shell command is presented as a manual fix. - **Rationale:** The suspicious indicators resolve to ordinary CLI behavior: Tonbo credentials go to Tonbo’s API, the foreign-looking key strings are explicitly fake test fixtures, and the installer command is only shown as a manual update suggestion. No install hook or concealed automatic credential forwarding was found. - **Network endpoints:** api.tonbo.dev, tonbo.dev, git.tonbo.dev, streams.tonbo.dev, registry.npmjs.org ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes a CLI entry point and has no install, preinstall, or postinstall hook., Management requests default to https://api.tonbo.dev; bearer credentials are sent to the configured API origin., TONBO\_API\_ORIGIN is an explicit override, and the source requires HTTPS except for loopback HTTP., The Anthropic key and JWT strings are explicitly fake test vectors for the secret-filtering behavior., The curl installer command is shown as a suggested version-update fix; it is not run automatically. - **Evidence against:** The CLI supports network requests and filesystem writes as part of its session capture and account-management features., The source includes a shell install command for manual upgrades and checks npm for the latest package version. ## Affected versions and remediation This report applies to @tonbo/yield@0.3.17. - Review the evidence and your use of @tonbo/yield@0.3.17 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.
