Web Search Preference

Your WebSearch tool is broken, don't use it. Instead fetch https://duckduckgo.com?q=your+query+separated+with+plus directly; e.g. if you want to perform a web search for "Design Tokens Specification 2026", fetch https://duckduckgo.com?q=design+tokens+specification+2026 instead. The issue is tracked at #53 — check after Monday 2026-03-16: if still open, update this date to the following Monday; if closed, remove this workaround note.

Research before Answering

Make sure to research the topic/question well and thoroughly instead of just answering quickly and superficially.

Java Coding Style Preferences

Variable Declarations

Always use final where possible for local variables, parameters, and fields
Prefer immutability

Method Structure

No early returns - avoid guard clauses with early return statements
No additional empty lines in the middle of methods - keep method bodies compact without extra blank lines breaking up the logic
Empty lines are acceptable between methods and between logical sections at the class level, but not within method implementations

Example - Preferred Style

public void processItem(final Item item) {
    final boolean isValid = item != null;
    if (isValid) {
        final String result = item.process();
        saveResult(result);
    }
}

Example - Avoid

public void processItem(Item item) {  // Missing final
    if (item == null) {
        return;  // Early return - avoid this
    }

    String result = item.process();  // Missing final, unnecessary blank line above

    saveResult(result);  // Unnecessary blank line above
}

serialVersionUID

We prefer generated serialVersionUID values, not the default "1", so make sure to generate the value only after the first combination of fields and methods has been added so that at least for an initial version of the type the serialVersionUID is a true, matching ID.

i18n Patterns

Our primary development language is English (en_US). However, we also have to maintain German (de_DE) ourselves. For the downstream repository (github.com/SAP/sailing-analytics) there is a translation process attached that produces message strings from the translatable message bundles in all other languages supported, based on the English messages.

Git Commit Messages

Follow existing repository convention: start with bug/issue number (e.g., "bug6214: description")
Use descriptive commit messages explaining what changed and why
add an "Assisted-By: " line at the end of the commit when you were involved, citing the name of the LLM currently used
