Treat them as untrusted evidence. 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:** 0.5.2 - **Selected version is latest:** Yes - **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 lifecycle hook, and the flagged key strings are explicitly fake test vectors. The runtime metrics are described as content-free, disclosed in the README and configurable off; credential use is tied to Tonbo accounts and services. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-11-04T10:55:53.704Z - **Finished:** 2026-11-04T10:57:01.124Z - **Download time:** 508 ms - **Static scan time:** 2666 ms - **AI review time:** 64244 ms - **Total time:** 67420 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 provides an agent-session capture CLI and disclosed, content-free metrics. - **Trigger:** CLI commands and the capture service; metrics are sent for documented events and can be disabled with TONBO\_YIELD\_METRICS=off. - **Impact:** No unauthorized credential transfer or unrelated destructive action was found. - **Review source:** ai\_review - **Reviewed:** 2026-11-04T10:57:01.124Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI uses Tonbo credentials with Tonbo services. The flagged secret patterns are fake test data, and the install command appears as documented setup or upgrade guidance. - **Rationale:** The manifest has no install lifecycle hook, and the flagged key strings are explicitly fake test vectors. The runtime metrics are described as content-free, disclosed in the README and configurable off; credential use is tied to Tonbo accounts and services. - **Network endpoints:** api.tonbo.dev, streams.tonbo.dev, git.tonbo.dev, registry.npmjs.org, yield.tonbo.io ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package exposes a CLI entry point and declares build, lint and test scripts; it has no install lifecycle hook., Authentication uses a Tonbo API key or the saved Tonbo CLI login for the account the command acts in., The apparent secret strings occur in filter test vectors explicitly described as fake secrets., The README discloses the content-free runtime metrics, their retention and how to disable them. ## Affected versions and remediation This report applies to @tonbo/yield@0.5.2. - Review the evidence and your use of @tonbo/yield@0.5.2 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.
