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:** 0.3.0 - **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 source implements the package’s stated session-capture purpose, and the persistent capture service is started by an explicit, login-gated CLI command. Although personal transcript lines are uploaded without redaction, that behavior is documented and the inspected credential flow does not redirect credentials to an unrelated host. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-01T20:18:03.658Z - **Finished:** 2026-11-01T20:19:11.060Z - **Download time:** 759 ms - **Static scan time:** 1094 ms - **AI review time:** 65548 ms - **Total time:** 67402 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 identified; the package provides an explicitly installed session-capture CLI. - **Trigger:** A user runs \`yield daemon install\` after logging in to enable capture. - **Impact:** Captured sessions may contain sensitive text, but this is the package’s stated capture behavior and no unrelated credential redirect was identified. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T20:19:11.060Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The daemon reads Claude and Codex session files and uploads their lines to the configured Tonbo session store. The README discloses that personal session lines are sent without redaction. - **Rationale:** The source implements the package’s stated session-capture purpose, and the persistent capture service is started by an explicit, login-gated CLI command. Although personal transcript lines are uploaded without redaction, that behavior is documented and the inspected credential flow does not redirect credentials to an unrelated host. - **Files touched:** ~/.claude/projects, ~/.codex/sessions, ${XDG\_STATE\_HOME:-$HOME/.local/state}/tonbo-yield/state.json - **Network endpoints:** api.tonbo.dev, streams.tonbo.dev, git.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 exposes a CLI and declares no install, preinstall, or postinstall hook., The background capture service starts only through the explicit \`yield daemon install\` command, which requires an existing login., The documented feature watches Claude and Codex session files and uploads their lines to capture sessions; the README discloses that personal session lines are sent without redaction., Code applies secret filtering to team sessions, while personal sessions use their original line; both are routed to session streams as part of the documented capture feature., The default management API is the package’s own \`api.tonbo.dev\` service; the inspected source does not establish an unrelated credential destination. - **Evidence against:** Personal session transcripts are uploaded without redaction, so they could contain credentials or other sensitive content. The package documents this behavior as part of its capture feature. ## Affected versions and remediation This report applies to @tonbo/yield@0.3.0. - Review the evidence and your use of @tonbo/yield@0.3.0 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.
