Tonbo Yield: capture your agents' sessions on every machine and list them from any.
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe flagged credential strings are fake examples in redaction tests, and the code uses Tonbo credentials with Tonbo service endpoints for the package’s stated capture purpose. The install-time download-and-run lead resolves to a status command’s suggested upgrade fix, not an executed shell pipeline.
Static reason
One or more suspicious static signals were detected.
Trigger
CLI commands; continuous capture follows user sign-in and capture-service setup.
Impact
No malicious impact identified. The intended behavior stores and shares captured sessions through the user’s Tonbo account.
Mechanism
Uses Tonbo’s API, Streams, and Git services for account, session, and snapshot features. The flagged API-key strings are fake redaction-test inputs, and the download command is presented as a status fix.
AI rationale
The flagged credential strings are fake examples in redaction tests, and the code uses Tonbo credentials with Tonbo service endpoints for the package’s stated capture purpose.

Decision evidence
public snapshotAI called this Clean at 98.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes a CLI executable and lists build and test scripts, with no install lifecycle hook.
- The README describes capturing coding-agent sessions and running a capture service as the package’s purpose.
- The credential code uses TONBO_API_KEY or a saved Tonbo login; the default API host is api.tonbo.dev.
- The Anthropic and OpenAI key strings appear in secret-filter test vectors explicitly described as fake; the filter replaces matched secrets with redaction markers.
- The README describes Alpha metrics as content-free and documents TONBO_YIELD_METRICS=off.
- The curl-to-shell string is used as a suggested status fix when a newer version is available; no execution of that string was found.
Evidence against
- The core feature uploads and snapshots coding-agent sessions after the user signs in and sets up capture.
- Alpha metrics are enabled by default, though the README describes their limited content and documents an opt-out.
