Intent
Buy Guy is built around a simple buying principle: search trusted shops, makers, and quality aggregators before falling back to broad marketplaces. The CLI turns a purchase question into a compact report with materials, care notes, vendor trust signals, concerns, and source links.
System
The workflow starts with a curated vendor registry, then uses Codex-backed live search for broader discovery when needed. Reports are saved locally, weak claims are marked for manual verification, and the guided starter keeps the prompt structured before search begins.
Current direction
The public evidence is the workflow rather than individual shopping results. The product work is in the trust-first search order, structured output contract, local report archive, and guardrails around unverifiable claims.
