Business Analyst

This is what you'd use before you write any PRD or start building. It runs structured discovery interviews, does competitive research, and outputs a complete product brief with problem definition, target users, and success metrics. The workflow uses parallel subagents for research, so you can spin up four agents simultaneously to tackle market analysis, competitive landscape, technical feasibility, and user needs while staying within context limits. Hands off cleanly to a product manager once the analysis is done. Best for when you're starting from a rough idea and need to validate problem-solution fit before committing to a roadmap.
