SDD Research Skill

Investigate codebase patterns and external solutions to inform specification and planning. Supports two modes: standard (codebase-focused) and deep (comprehensive external investigation).

When to Use

• Technical approach is unclear
• Need to understand existing patterns
• Evaluating solution options
• Before /specify or /plan commands
• Deep research: New domain, unfamiliar technology, high-stakes architectural decision, or when standard research yields insufficient clarity

Research Modes

Standard Research (default)

Quick internal + surface external analysis. Good for well-understood domains where the codebase already has relevant patterns.
