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 and bundle describe a session-capture CLI that sends its feature data to Tonbo’s API using Tonbo account credentials. The scanner’s apparent credential redirect and download-and-run leads resolve to fake filter examples and a printed upgrade instruction, respectively. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-04T06:41:21.384Z - **Finished:** 2026-11-04T06:42:00.925Z - **Download time:** 510 ms - **Static scan time:** 2632 ms - **AI review time:** 36397 ms - **Total time:** 39541 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 is a CLI for capturing agent sessions to Tonbo. - **Trigger:** The user invokes the Yield CLI; session capture and account operations use the configured Tonbo account. - **Impact:** Session data is handled by the package’s stated capture feature; the inspected source showed no unrelated credential redirection or automatic download-and-execute behavior. - **Review source:** ai\_review - **Reviewed:** 2026-11-04T06:42:00.925Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI sends feature data to its Tonbo service using a Tonbo account credential. The scanner’s credential matches are fake filter-test examples, and the apparent shell command is displayed as upgrade guidance. - **Rationale:** The manifest and bundle describe a session-capture CLI that sends its feature data to Tonbo’s API using Tonbo account credentials. The scanner’s apparent credential redirect and download-and-run leads resolve to fake filter examples and a printed upgrade instruction, respectively. - **Files touched:** package.json, dist/bin/yield.js - **Network endpoints:** https://api.tonbo.dev ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest describes Yield as capturing agents’ sessions and exposes dist/bin/yield.js as its CLI., The bundled API client defaults to https://api.tonbo.dev, consistent with the package’s Tonbo service., The credential code uses TONBO\_API\_KEY or the Tonbo CLI login as the account credential for commands., The bundle describes an on-device secret filter for team session capture; the credential-like strings flagged by the scanner occur in filter test vectors as fake examples. - **Evidence against:** Using a CLI login is required for account operations, and the source describes that credential as belonging to the account the command acts in., A download-and-run scanner match is an upgrade command in an error message, not an automatically executed shell command., No install lifecycle scripts are declared. ## Affected versions and remediation This report applies to @tonbo/yield@0.5.0. - Review the evidence and your use of @tonbo/yield@0.5.0 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.
