Usage, health checks & privacy

The last group of features keeps you informed and safe: what you are spending, what is misconfigured, and how Berth protects your data.

Usage

Cost and token trends by model, by project, and by day, with rate-limit headroom kept in plain sight. When a session lacks cost data, Berth shows "unknown" rather than a misleading $0.

Health checks

Automated local diagnostics catch common problems: syntax errors, missing required fields, broken @path imports, and unsafe settings — each with a severity and, where possible, a suggested fix.

Privacy & read-only

Berth runs entirely on your machine: no telemetry, no cloud sync, no account. v0.1 never modifies a file, and credentials are detected for status only — never displayed.
