Idea Reality Check

When to use

• Starting a new project or side project
• Evaluating whether to build or buy
• Researching competitors before a sprint
• Validating a feature idea before implementation

Instructions

1. Ask the user for a natural-language description of their idea
2. Call the idea_check MCP tool with the idea text
3. Use depth="quick" for fast checks (GitHub + HN), depth="deep" for comprehensive analysis (all 5 sources)
4. Present the reality_signal score (0-100) and interpret it:
   • 0-30: Low competition — green light to build
   • 31-60: Moderate competition — differentiation needed
   • 61-80: High competition — find a niche or pivot
   • 81-100: Very high competition — consider contributing to existing projects instead
5. List the top 3 competitors with star counts and descriptions
6. Share the pivot_hints for actionable next steps
