Respect Walmart's llms.txt directive prohibiting transactional agent actions while still using Walmart's permitted product-discovery endpoints for a shopping agent

Steps

1. Fetch and parse Walmart's llms.txt to confirm current guidance on what agent actions are and are not permitted before building any integration
2. Restrict your agent to read-only product discovery and catalog browsing against Walmart's publicly documented endpoints, avoiding any attempt to script cart or checkout actions directly against walmart.com
3. For transactional intent, redirect the user to complete the purchase on Walmart's own surface (site, app, or an authorized partner integration like ChatGPT's Walmart deal) rather than automating checkout yourself
4. Track that Walmart's posture is evolving -- it has separately partnered with OpenAI to sell within ChatGPT and has discussed integrating its own Sparky assistant into third-party agent surfaces
5. Re-check the llms.txt file periodically for changes, since marketplace agent policies in this space are being revised frequently
6. Fail closed: if the policy is ambiguous for a given action, default to human handoff rather than assuming automation is permitted
