Configuration options should be designed with clarity, consistency, and user experience as primary concerns. This includes several key practices: **Clear and specific help text**: Flag descriptions should explicitly explain their purpose and scope to avoid user confusion. For example, instead of generic descriptions, be specific about when and how the flag is used. **Intuitive syntax with units**: When accepting time or quantity values, include units in the syntax for clarity. Use formats like `30s`, `5m`, `1h` instead of raw numbers, and document the expected format. **Consistent behavioral patterns**: Maintain consistent conventions across similar flags. For example, if `0` disables functionality in some flags, apply this pattern consistently across related options. If `0` means "run immediately" for some flags, use the same convention for similar flags to reduce user confusion. **Validation with helpful errors**: Prefer clear error messages over warnings for invalid configuration values. This reduces warning spam and makes it easier to evolve behavior later. Provide actionable feedback when validation fails. **Proper option organization**: Place configuration options in appropriate option classes that reflect their actual usage and dependencies, rather than generic catch-all classes. Example of good configuration design: ```java @Option( name = "timeout", converter = DurationConverter.class, help = "Timeout for action execution. Use format like '30s', '5m', or '1h'. " + "Set to 0 to disable timeout.") public Duration timeout; ``` This approach ensures configuration options are self-documenting, behave predictably, and provide a better developer experience.
