Claude Code Instructions

Coding Style

Minimize comments. Code should be self-explanatory. Only add comments when the logic is truly non-obvious.
No blank lines inside methods. Keep method bodies compact without empty line separators.
Never use single-letter abbreviations in lambdas. Use descriptive names like entry, text, value, event, etc.
Use types and functions from @opendaw/lib-std instead of inline checks:
- Use Optional<T> instead of T | undefined
- Use Nullable<T> instead of T | null
- Use isDefined(value) instead of value !== undefined or value !== null
- Use !isDefined(value) instead of value === undefined or value === null
- Use isAbsent(value) instead of value === undefined || value === null
- Never use falsy checks like !value or if (!value) for null/undefined checks - always use !isDefined(value) or isAbsent(value)
- Never write | null or | undefined inline - always use the lib-std types.
