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 credential-redirection and secret-pattern alerts are not borne out by the source: the apparent secrets are fake test fixtures, and the access-token flow sends Tonbo credentials to the configured Tonbo origin. The manifest has no install lifecycle hook, and the CLI's network activity matches its documented session-capture purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-11-02T07:58:41.748Z - **Finished:** 2026-11-02T07:59:55.689Z - **Download time:** 510 ms - **Static scan time:** 1273 ms - **AI review time:** 72157 ms - **Total time:** 73941 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 CLI for capturing, syncing, and recalling coding-agent sessions. - **Trigger:** The CLI runs when the user invokes the yield command; login and capture setup are user-initiated. - **Impact:** No malicious impact was identified in the reviewed source. - **Review source:** ai\_review - **Reviewed:** 2026-11-02T07:59:55.689Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It uses the configured Tonbo API origin and exchanges Tonbo credentials for audience-specific Streams or Git access tokens. - **Rationale:** The credential-redirection and secret-pattern alerts are not borne out by the source: the apparent secrets are fake test fixtures, and the access-token flow sends Tonbo credentials to the configured Tonbo origin. The manifest has no install lifecycle hook, and the CLI's network activity matches its documented session-capture purpose. - **Files touched:** package.json, dist/bin/yield.js, README.md - **Network endpoints:** https://api.tonbo.dev, https://tonbo.dev/api/iam/token, https://streams.tonbo.dev, https://git.tonbo.dev, https://registry.npmjs.org/@tonbo/yield/latest, https://yield.tonbo.io/install.sh ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes a CLI and declares no install, preinstall, or postinstall lifecycle hook., The API origin defaults to Tonbo; a different origin must be explicitly supplied through TONBO\_API\_ORIGIN and pass HTTPS validation., The access-token exchange sends a Tonbo login key to the configured Tonbo user origin for a Streams or Git audience., The credential-looking strings in the bundle are test fixtures explicitly described as fake secrets., The executable parses the user's CLI arguments at startup; the README describes session capture and recall as the package's purpose. - **Evidence against:** The package reads its own Tonbo login key or TONBO\_API\_KEY for Tonbo API operations; the reviewed flow does not redirect Anthropic or OpenAI credentials., Session capture and uploads are core documented functionality, and no unrelated collector or concealed automatic action was identified. ## Affected versions and remediation This report applies to @tonbo/yield@0.3.4. - Review the evidence and your use of @tonbo/yield@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.
