Claude to compare speakers from local catalogs

Daniel Rosehill published a Claude Code workflow for choosing a portable Bluetooth speaker. He supplied a specification file describing the intended use and budget, alongside screenshots from retailer catalogs, so the comparison could start from available products rather than an unconstrained product search.

The repository separates catalog extraction from price analysis. A catalog scanner turns the captured offers into structured JSON, and a price analyst compares the candidates with the personal requirements. The workflow then produces a recommendation report in Typst and exports it as a PDF.

Rosehill used Gemini through MCP for research grounding. The repository also discusses browser and scraping configurations, but those optional integrations are not evidence that every one was used for this comparison. The reported recommendation was a JBL Flip 7 listed at ₪349 by KSP, with other lower priced and premium candidates retained in the comparison.

This is a product evaluation artifact, rather than a verified purchase. The repository includes estimates about sound and relative value, but no measured loudness test or order receipt. The practical pattern is to keep the user's requirements and the extracted retailer offers separate, then ask the agent to explain a recommendation from those two inputs. Rosehill published the workflow and the generated report for inspection.
