Personal agents for vertical shopping: cross-site catalogues via Claude artifacts and a soul file

signulll · x · 2026-09-25

@nikitabier points out an interesting opportunity for personal agents: rapidly generating highly verticalized shopping experiences that horizontally filter inventory across multiple sites — e.g. asking a bot for a catalogue of every brown wool sweater, or something as precise as "4 inch aluminum tube with a flange," which was always cumbersome with Google search.

signulll replies with a concrete technique: have Claude create artifacts, and keep design guidelines for artifacts in a soul file, so every artifact stays interactive and consistent whether it's a product list or a reading digest.

Takeaway: encoding design specs into a personal config file makes agent output reliably usable, and vertical shopping catalogues look like a concrete application-layer direction for agents.
