Configuration Precedence

  1. Environment variables (highest priority)
  2. Bot config.csv
  3. Default values (lowest priority)

Environment variables always override config.csv settings.

Validation

On startup, General Bots validates configuration and logs warnings for:

  • Missing required settings
  • Invalid values
  • Deprecated options
  • Security concerns (e.g., weak rate limits)

Check logs for configuration issues:

RUST_LOG=info cargo run 2>&1 | grep -i config
