Tonbo Yield: capture your agents' sessions on every machine and list them from any.
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe package provides a session-capture CLI with no install lifecycle hook, and the reviewed credentials are used for Tonbo services. The scanner’s apparent third-party secrets occur in redaction test fixtures, not an exfiltration flow.
Static reason
One or more suspicious static signals were detected.
Trigger
User invokes the yield CLI; session capture uses the configured or saved Tonbo login.
Impact
No malicious credential redirection, install-time behavior, or unrelated automatic action was identified.
Mechanism
The CLI authenticates to Tonbo services and handles session data for capture. The flagged provider credential strings are test fixtures with redaction examples.
AI rationale
The package provides a session-capture CLI with no install lifecycle hook, and the reviewed credentials are used for Tonbo services. The scanner’s apparent third-party secrets occur in redaction test fixtures, not an exfiltration flow.

Decision evidence
public snapshotAI called this Clean at 96.0% 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 CLI reads TONBO_API_KEY or a saved Tonbo login for authentication.
- The default management API is https://api.tonbo.dev; token audiences include Tonbo’s Streams and Git services.
- The apparent Anthropic key and JWT are fake test data, with expected output showing both redacted.
- The bundle’s entrypoint parses CLI arguments; the package describes its purpose as capturing agent sessions.
