Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.4.1 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The manifest has no install hook, and the reviewed API flow sends the Tonbo credential to the Tonbo management API. The flagged OpenAI and Anthropic patterns occur in redaction fixtures; no code reading those provider credentials or redirecting them was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-03T12:58:30.335Z - **Finished:** 2026-11-03T12:59:27.284Z - **Download time:** 761 ms - **Static scan time:** 2248 ms - **AI review time:** 53938 ms - **Total time:** 56949 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; this package provides a Tonbo session-capture CLI. - **Trigger:** The CLI runs when a user invokes the yield command. - **Impact:** No unauthorized credential forwarding or other malicious behavior was found in the reviewed source. - **Review source:** ai\_review - **Reviewed:** 2026-11-03T12:59:27.284Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected credential flow uses the Tonbo management API; the suspected third-party API keys appear only in redaction test data. - **Rationale:** The manifest has no install hook, and the reviewed API flow sends the Tonbo credential to the Tonbo management API. The flagged OpenAI and Anthropic patterns occur in redaction fixtures; no code reading those provider credentials or redirecting them was found. - **Network endpoints:** https://api.tonbo.dev, https://yield.tonbo.io/install.sh ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes dist/bin/yield.js as the CLI and declares no install lifecycle script., The CLI's management API uses https://api.tonbo.dev as its default origin., The management API sends its bearer credential to a URL built from that configured origin., The apparent OpenAI key is in a redaction test fixture, not code that reads the environment variable. - **Evidence against:** The bundle references a curl-to-shell upgrade command, but the inspected source shows it as a command string for status repair, not an install hook., The CLI reads TONBO\_API\_KEY, which is the credential for the package's own Tonbo service. ## Affected versions and remediation This report applies to @tonbo/yield@0.4.1. - Review the evidence and your use of @tonbo/yield@0.4.1 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.
