# shopping-aggregator A thin orchestration layer for consumer shopping price comparison. It does **only three things nothing else does**: (1) parse a buy intent into a triage of the right shopping domains + channel classes; (2) detect which specialized shopping MCP / extension / OSS tool is connected and guide installing missing ones; (3) enforce **price-specific** guardrails (snapshot timestamp, stock state, landed-cost normalization, coupon-cart verification, retailer trust tiers). The heavy lifting, live page fetch, history backfill, adversarial verification, citation synthesis, is **delegated** to playwright / BigGo / Keepa MCPs / `deep-research` / `market-intel`. Do not re-implement those. > **Design philosophy (governs all changes): root-cause design, not incremental patching**, fix the > assumption underneath a problem, not the symptom on top. Full statement in `PHILOSOPHY.md`; every > change must pass "does it fix the framing, or just patch a symptom?" ## Scope, when this skill applies, and when to stop **Use this skill** for the consumer buy decision: "compare prices / find the cheapest place to buy X", "is this a good deal / should I wait for a sale / what's the historical low". **Stop and delegate** otherwise, before doing anything, route away these non-buy-decision asks: - **Single retailer + already picked** ("just check Amazon for Bose QC45") → open the page, no workflow. - **Bulk arbitrage / FBA sourcing / supplier discovery** → `market-intel` `ecommerce-ar
