SW Hi, I am Scott Watermasysk.

AI did not replace my craft. It gave it leverage.

I am a software developer and product builder with twenty-plus years of shipping. I write Ruby, start things from scratch, run products for the long haul, and use AI to cover more ground without outsourcing the judgment.

I wonder if “shared prompting” could help counter the deep code understanding that AI coding has eroded: two or more people working together with a single prompt/workflow.

My model breakdown: Fable - the only reason I use Anthropic models for anything. I typically use it for planning. Sol/Luna - the workhorses.

We should be prototyping more. Plans, specs, etc. are helpful, but there’s nothing like actually trying something out.
