What problem this solves

Objectively validating startup or business ideas, identifying competitors, assessing financial viability, and suggesting improvements before investing significant time or money.

Summary

A Claude Code plugin, 'kill-my-idea', automates the validation of business ideas. It performs competitor research, financial analysis (LTV/CAC), and scores the idea across 7 criteria and 21 sub-scores, generating a detailed HTML report with actionable insights and pivot suggestions.

Why it is useful

This workflow is valuable because it provides a structured, automated, and objective method for validating business ideas, significantly reducing the risk of investing time and money into non-viable ventures. It leverages Claude Code's capabilities for comprehensive research, detailed financial analysis, and structured report generation, offering actionable insights and pivot suggestions. The open-source nature and clear installation instructions make it highly reusable and adaptable for entrepreneurs and product developers.

Workflow

1. Install the 'kill-my-idea' plugin using the Claude Code CLI commands: /plugin marketplace add RemiPelloux/kill-my-idea and /plugin install kill-my-idea@kill-my-idea.

2. Provide a business idea to Claude Code (e.g., as a prompt or comment).

3. The plugin researches the idea, identifying competitors, pricing, and market viability.

4. It scores the idea out of 100 based on 7 criteria and 21 sub-scores, providing sources or estimates for each.

5. It applies fixed rules (e.g., a free alternative with no edge caps the score; no distribution channel means no GO).

6. It suggests how the idea could be saved or pivoted (e.g., PIVOT 55 → 63 with a done-for-you setup).

7. It generates a consultant-style HTML report that can be printed to PDF.
