Tonbo Yield: capture your agents' sessions on every machine and list them from any.
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe 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.
Static reason
One or more suspicious static signals were detected.
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.
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.
AI 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.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
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.
