I’d love to hear more about your thoughts on draft tours! Currently, you can record as many tours as you want per codebase, and so you could record one that was scoped to just key API calls, and have n-number of other ones with more detail, alternate flows.

Would that satisfy what you’re thinking? Or were you thinking about being able to record a tour, and mark certain steps as being more important than others? Any feedback here is unbelievably valuable!

I meant a way to make up-to-date drafts: base it on an automatic execution trace, like from a debugger running the code.

You get this 100% up-to-date trace for free. It's crazy verbose, so apply filtering (e.g. to only key apis) to make it manageable. Then edit that draft manually. Like an annotated, abbreviated, step-into debugger.

My thinking is that this makes it easier to get an initial draft. But maybe that basic trace is easy and natural to do manually?

Also, I'm not sure how similar this "execution trace" would be to a tour based on explaining it... I suppose you could find out, by examining your best tours to see how closely they actually follow execution order (if at all). When I try to understand a codebase, I do trace calls manually, so there's probably some similarity.

Ah OK cool, apologies for misunderstanding you. Now that I’ve got the core record/playback experience, I’m keen to explore ways to simplify the authoring and maintenance experience even further. Enabling a “code profiler” for recording/updating tours could definitely be really useful. Thanks for the feedback!

No worries, think your interpretation of just api calls is a good one, a bit like "tests as documentation". Could then have another tour for each module (api implementation). This approach would tend to confine the effect of changes (as in Parnas' On the Criteria To Be Used in Decomposing Systems into Modules https://www.win.tue.nl/~wstomv/edu/2ip30/references/criteria...)

Though multiplicity of tours is also complexity!
