Steps
Once connected (see setup above), use the Dupe Finder tool:
- Define the target product and your application's display schema for alternatives.
- Ask Copilot to use `dupe-finder` with `find_dupe` to find alternatives.
- Have Copilot return the results as typed JSON matching your schema.
- Feed the output into your comparison UI, recommendation engine, or shopping assistant.
Example Prompt
Try this with Copilot using the Dupe Finder tool
Use dupe-finder to find cheaper alternatives to the Dyson V15 Detect (£599). Return results as JSON matching this schema: {alternatives: Array<{name: string, brand: string, price: number, currency: string, similarity_score: number, key_differences: string[], buy_url: string}>}.
Tips
- Include `similarity_score` as a numeric field so your UI can sort by closest match.
- Return `key_differences` as an array of strings for clean rendering as bullet points in the UI.
- Include `buy_url` so users can go directly to the product without additional search steps.
