Diagnostics

Settings → About → Diagnostic Report generates an environment info report for support.

What to Include When Reporting an Issue

Providing these dramatically speeds up diagnosis:

  1. Diagnostic report: Settings → About → Diagnostic Report, one click
  2. Session ID: right-click the affected session in the sidebar → Rename; the ID in the dialog title is the session ID (also findable in the diagnostic report)
  3. Reproduction steps: what you did from launch to the error; stable repro is best, note frequency for intermittent issues
  4. Error screenshots: include the error card in the message stream, not just the popup

No need to worry about sensitive data: API keys and tokens in diagnostic reports and logs are masked—safe to share.

Log Location

When you need to inspect logs manually (e.g., support asks). Logs are a single JSONL file with structured events from the main process, kernel, and tool calls; API keys, tokens, and message bodies are all masked:

OS Path
macOS/Linux ~/.lanmate/agent/logs/
Windows %USERPROFILE%\.lanmate\agent\logs\
