I’d like to build something myself rather than just clicking through a template, mostly so the concepts actually stick. What does the path from blank canvas to working workflow look like? I’m curious about where people usually start, what the first few actions tend to be, and any habits that make the build go smoothly. Happy to be pointed at a walkthrough if one exists.
For me, there’s only one place to start with building out workflows these days, and that’s Plan mode. I’ve strong feelings about people who don’t use it when starting out (mostly: are you mad?!?).
Instead of watching an AI start writing and rewriting things on a vague prompt and hoping for the best, you get to co-build a concrete, reviewable plan first. Structure, what it’ll interact with, failure modes, etc. So you can catch a bad assumption or wrong approach in five seconds instead of untangling a mess later. And it’s especially valuable for anything risky or unfamiliar.
Given the cost involved in building and rebuilding a workflow, it’s also more cost-effective.
I could go on. 
tl;dr - Absolute no-brainer for me when building a workflow.
