I’m bringing this one back to one of the first agent-specific tools I built back in February.
Geez… that feels like forever ago now.
The Catalog CLI.
What started as a pain point for a client turned into a tool that I have used, other people have used, and a few people have even modified and commercialized.
Which is totally allowed under the license, and honestly, I love that.
But the bigger thing is this:
Catalog CLI is what spawned a lot of what I’m building today.
It was the diving board into the pool.
It helped me see what was possible when you take real Amazon catalog problems, wrap them in better tooling, and start giving agents a more structured way to work through the chaos.
The tool has its own agent now and has helped me identify listing gaps, backend issues, and areas where listings were not as clean as they looked on the surface.
And I’m not done with it.
It is still available open source, and there is a Pro feature for $10/month that gives you some solid added benefits.
But right now, I’m working on bringing Catalog CLI into Codex as an official plugin.
And no, this is not a “you should only use Codex” post.
I use Claude. I use Codex. Claude Code still houses parts of my agents. The other parts live in local automations and my vault, which acts more like the brain.
But the way Codex is developing right now is interesting.
Really interesting.
Having your catalog connected inside Codex, paired with a proper harness, could be extremely powerful.
Imagine being able to check catalog issues, review listing gaps, and start working through Amazon problems from your phone.
That is where this starts to get fun.
Oh, and one more thing…
No more Rufus scoring.
I brought in the COSMO science paper, so listings are now scored against that framework instead.
Not much changed, to be honest, but it is a cleaner and more accurate way to think about listing quality.
Catalog CLI was the first real step for me.
Now it is becoming part of a much bigger system.
More coming soon.
