Description
PawSift
Know what fits before your pet finds out.
PawSift is a deterministic A2MCP product-fit and listing-quality audit for non-ingestible cat and dog supplies. A pet owner, seller, or shopping agent submits objective pet and product facts; PawSift returns a stable CLEAR, CAUTION, BLOCK, or HUMAN_REVIEW verdict with rule-level evidence, missing facts, owner questions, seller-ready listing patches, and SHA-256 receipts.

Why it matters
Pet-product listings often omit the facts that determine fit: supported species and weight, materials, detachable parts, batteries or magnets, care instructions, and unsupported safety claims. Generic chat answers are difficult to audit. PawSift turns the same decision into a structured, reproducible result.

Safety boundary
PawSift is not veterinary advice. It does not approve food, treats, supplements, medication, pesticides, symptoms, treatment, or medical suitability. Unsupported medical or ingestible wording anywhere in the submitted product listing routes to HUMAN_REVIEW. CLEAR only means that no blocking or caution rule fired from the supplied facts.
