On the other hand, I also get the sense that for a very large organization with siloed teams that sure, the org moved to bring all the endpoint timestamps to a standard 3339 and either you never got the memo or your endpoint being misaligned would get caught at code review time and changed then but the agent was proactive here and went ahead and saved some time. Like, truly, I get that the marginal gains there add up on the balance sheet.

But what about when it is important that your APIs timestamps stay unaligned as epoch? Do you now need to set an override to meta-program that field for the AI as an additional token in the context window every time it runs?

Part of me is impressed for sure about what’s being achieved, but then another part is like “is the boilerplate of copying in the database field names and then shift+alting to write 100 lines of { get; set; } at the same time really so terrible for everyone?” I’m being hyperbolic for effect but I think my point is clear.

There’s also a third part of me that feels like I’m watching the creation of credit-default swaps of tech debt. If no one has time to do the changes that seem like a lot of work to a large organization with inertia because no one has the breadth of mastery needed to implement them as efficiently as possible, how the heck is anyone going to audit and fix the behavior when subtle mistakes eventually cascade?

Is this just the coding version of Amazon outsourcing their shipping to third party contractors that definitely led to people dying but shielded Amazon from liability? Like, “oops, sorry we don’t know why the AI changed our code and your bank account got emptied, we’ll look into it, but it’s not our fault, just the vagaries of fate!”

Again, I do understand the possible business savings in the short term in terms of administrative overhead, but I really shudder at the possible downstream effects of agentic code at scale and I’m trying to understand the real savings for a user that outweighs the downside risk of blowing up your production system and then being in a position of no one suited to fixing it who is responsible to do so.

One thing I think you've got very right here is the relatively spare use of fields in your schema models. I can't emphasize enough how much that will help a seller that uses this, since so many small business owners and employees out there don't know what they don't know and are making it up on the fly and tend to focus on the wrong things. Not a lot of headspace for the "nothing missing, but nothing unnecessary" approach when you're trying to juggle every hat because you're understaffed, and doubly so when you've never even heard the term many-to-one. Of course, because this is open-source, if users want they can extend these schemas (and even extend the views to use them! etc.), but they'll have to go out of their way to do that, not start with a tangled mess of concepts and pare them down. Really, it seems like no big deal, but humble schemas are so so important. At my current job I'm having the fun time of maintaining true spaghetti software with hundreds of fields in tables, a lot of which are null (or empty string! but which is it?), and all of which have no field names beyond a number...to power a POS/inventory system. But don't worry, none of the data is normalized and it pre-aggregates your transactions to compress itself, and then writes those compressed records into an always existing "temp" table and then reads them every time you want a report, and look at that, it takes 5 minutes to generate a COGS report for last week that is a sub 5 ms SQL query. Ugh.

I guess where I'm going with this is that there is so much crapware out in the world, absolute trash that needlessly overcomplicates the problem it addresses, that continues to get its license renewed every year because the clients its sold to now believe its a truly hard problem, but if you look under the hood it's actually just some WSYWIG editor generated garbage that is trying to be everything and so instead is nothing usable, and their sales staff will tell you "just upgrade to our new microservices design to solve those legacy issues!" Every project like yours that takes what is a fairly traditional, well-trod problem and brings it into the open-source realm in a readable and straightforward way is a big win for small-time entrepreneurs. Please keep going with this.

I think you have something here, but the hardest part will be marketing it if you're trying to do this for a living. There are absolutely an absurd number of small businesses out there living or dying by their ecommerce sales who are either struggling to actually use the tools and workflows they currently have or are paying far more than they need to for sub-optimal solutions to this problem. They will not come to you first over the internet because they are not looking for open-source sales software, because they don't know what open-source is, but some honest shoe-leather work pounding the pavement and identifying the larger businesses around you physically or trawling through the business formation records in your county might pay real dividends, even if it's just an HN "lifestyle" business for you with recurring revenue comparable to the average salary.

As a final thought, when you do get to integrating Seller Central, you should look at bringing the different API services out there into your project for dashboards and the like. Maybe you don't want to deal with all that, but being able to flip through market metrics from all the different sales channels and even integrate them together would be a killer feature. In particular I'm thinking of https://keepa.com/#!, but I know other people use https://www.rainforestapi.com/ too. Don't know about the other e-commerce marketplaces out there but I'm sure they have them too.

Congrats on a getting a ten year long lurker to actually post.
