Meaning, give you an example?

This morning I created a new project. I provided a postgres database URL to a remote service (with a non-standard connection string, includes a parameter "?sslmode=require"). Then, I said:

  * "Write me a fastapi project to connect to a postgres database using a database url."
  * "Retrieve the schema from the remote database." It used psql to connect, retrieves the schema. That was unexpected, it figured out not only a coding task, but an external tool to connect to a database and did it without anything more than me providing the DATABASE_URL. Actually, I should say, I told it to look inside the .env file, and it did that. I had that URL wrong initially, so I told it to reload once I corrected it. It never got confused by my disorganization. 
  * It automatically added sqlalchemy models and uses pydantic once it figured out the schema.
  * "Create a webpage that lets me review one table."
  * "Rewrite to use tailwindcss." It adds the correct tailwindcss CDN imports.
  * It automatically adds a modal dialog when I click on one of the records.
  * It categorized fields in the database into groupings inside the modal, groupings that do indeed make sense.

I know the devil is in the details, or in the future. I'm sure there are gaping security holes.

But, this saved me a lot of time and it works.

And, the update is that in the last hour claude somehow removed the rendering of the actual items. It is clever in troubleshooting: it created mocks if the data could not be loaded, it added error messages with the number of items retrieved. But, it does not have access to my browser console nor the DOM, and therein lies the problem. It is slow to copy and paste back and forth from the browser into the terminal. But, this feels like a great opportunity for a browser extension.

But, my takeaway is that I could have fixed this exact problem in five minutes if I had written the JS code. But, I have not looked at anything other than glancing at the diffs that fly by in the session.

I used claude to create a piece of software that can render gerber files (essentially vector files used in electronics manufacturing), overlay another gerber file on top of it with exact alignment, and then provide a GUI for manually highlighting components. The program then calculates the centroid, the rotation, and prompts for a component designator. This all then gets stored in a properly formatted Place file, which is used for automating assembly.

The day before this I was quote $1000/yr/user for software that could do this for us.

I used Claude + aider to create a webhook forwarding service (receives webhooks, forwards them to multiple destinations, and handles retries, errors, etc). Included a web interface for creating new endpoints and monitoring errors, and made it fully dockerized and ready to be deployed into a kubernetes cluster.

Took me like 3 hours and a few dollars in api credits to build something that would have taken me multiple days on my own. Since it's just an internal tool for our dev environments that already does what we need, I don't care that much about maintainability (especially if it takes 3 hours to build from scratch). That said, the code is reasonably usable (there was one small thing it got stuck on at the end that I assisted with).

Claude Code and Aider, or aider using claude sonnet as the model? If you are using both claude code and aider I would love to know why.

Aider + Claude sonnet as the model.

I wanted a whiteboard app - simple, infinite, zoomable, scrollable svg-based area with custom shapes and elements. It just needed prompts like "add zoom", "add a rect shape", "add control points for resize", "add text shape", "make position attributes able to reference another objects properties, + basic arithmetic" (for example to make line connect 2 objects, or size of one mirror size of another, etc.). It made all of these with so little effort from me. I would never undertake such a project without an LLM.
