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 matches the package’s stated purpose: it captures agent sessions and syncs them to Tonbo using Tonbo credentials. There is no install hook, and the background capture service requires an explicit command to install or run it.
Static reason
One or more suspicious static signals were detected.
Trigger
The user runs a CLI command; ongoing capture starts only after `yield daemon run` or the explicit `yield daemon install` command.
Impact
The service uploads captured agent session content for the package’s stated purpose; no unrelated credential transfer or hidden automatic startup was identified.
Mechanism
The daemon reads Claude Code and Codex session files, stores capture state locally, and sends session records using a Tonbo login to Tonbo services.
AI rationale
The source matches the package’s stated purpose: it captures agent sessions and syncs them to Tonbo using Tonbo credentials. There is no install hook, and the background capture service requires an explicit command to install or run it.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json declares a CLI binary and no install, preinstall, or postinstall hook.
- The README describes capturing and listing Claude Code and Codex sessions as the package’s purpose.
- The README says capture reads agent session files and sends their records.
- The daemon service is installed only by the explicit `yield daemon install` command, which requires a saved login.
- The CLI uses `https://api.tonbo.dev` by default and uses a Tonbo API key or saved Tonbo login for requests.
- The binary dispatches commands through Commander’s `parseAsync`; no separate import-time action was identified.
