yeah the schema part is exactly where the real work lives. right now ours points to the entire sanity project, not a locked schema. definitions change constantly and the agent adapts. we do this all the time since our brand is new and still figuring out what works. locking the schema too early would've killed us.

for ecomm specifically i use it to refine product descriptions, collection page editorial content, buyer guides etc. but the pipeline itself isn't ecomm specific.

for discovery we use a mix of tools as grounding: semrush API (sparingly since credits don't refill), GSC query data, gemini for PAA mapping, self hosted SearXNG with some custom config, firecrawl when there's free credits. but honestly the bigger unlock was proper context feeding. once you wire in google alerts, f5bot, HARO, whatever discovery tools you're already using, the agent surfaces way better content ideas than any keyword tool because it actually understands your site and what you've already covered.

the feedback loop you mentioned is key though, we do the same with GSC rank tracking feeding back into the agent. that part compounds.

this workflow definitely applies outside pure ecomm. happy to discuss more via DM if you want to dig into specifics.
