Yesterday I fed claude very surgical instructions on how the bug happens, and what I want to happen instead, and it oneshot the fix. I had a solution in about 5 minutes, whereas it would have taken me at least an hour, but most likely more time to get to that point.

Literally an hour or two of my day was saved yesterday. I am salaried at around $250/hour, so in that one interaction AI saved my employer $250-500 in wages.

AI allows me to be a T shaped developer, I have over a decade of deep experience in infrastructure, but know fuck all about front end stuff. But having access to AI allows me as an individual who generally knows how computers work to fix a simple problem which is not in my domain.

My process, which probably wouldn't work with concurrent agents because I'm keeping an eye on it, is basically:

- "Read these files and write some documentation on how they work - put the documentation in the docs folder" (putting relevant files into the context and giving it something to refer to later on)

- "We need to make change X, give me some options on how to do it" (making it plan based on that context)

- "I like option 2 - but we also need to take account of Y - look at these other files and give me some more options" (make sure it hasn't missed anything important)

- "Revised option 4 is great - write a detailed to-do list in the docs/tasks folder" (I choose the actual design, instead of blindly accepting what it proposes)

- I read the to-do list and get it rewritten if there's anything I'm not happy with

- I clear the context window

- "Read the document in the docs folder and then this to-do list in the docs/tasks folder - then start on phase 1"

- I watch what it's doing and stop if it goes off on one (rare, because the context window should be almost empty)

- Once done, I give the git diffs a quick review - mainly the tests to make sure it's checking the right things

- Then I give it feedback and ask it to fix the bits I'm not happy with

- Finally commit, clear context and repeat until all phases are done

Most of the time this works really well.

Yesterday I gave it a deep task, that touched many aspects of the app. This was a Rails app with a comprehensive test suite - so it had lots of example code to read, plus it could give itself definite end points (they often don't know when to stop). I estimated it would take me 3-4 days for me complete the feature by hand. It made a right mess of the UI but it completed the task in about 6 hours, and I spent another 2 hours tidying it up and making it consistent with the visuals elsewhere (the logic and back-end code was fine).

So either my original estimate is way off, or it has saved me a good amount of time there.

It's outdated, doesn't differentiate between people trying to incorporate it in their current workflow and the people who apply themselves to entirely new ones. It doesn't represent me in any way and I am releasing features to my platform daily now, instead of weekly. So I can wholeheartedly disagree with its conclusion.

The earth is either flat of it isn't. It's easy to proof it's not flat. It's not easy to conclude that the results of a study in a field that changes daily represents all people working in it, including the ones who did not participate.
