In-depth research on technical topics using web search, documentation, and codebase analysis. Use when asked to 'research', 'investigate', 'find out about', 'look into', 'dig into', 'compare X vs Y', 'what's the best library for', 'how does X work', 'should we use', 'find alternatives to', 'evaluate options for', 'what are others doing for', or explore unfamiliar technologies, libraries, or architectural patterns. Also triggers for technology evaluation, migration research, and dependency decisions.
