Ask HN: Video showing LLM assitent coding on big code base

2•CopyOnWrite•1y ago
As a experienced software developer I read a lot about how AI tools make coding faster and speed up development of software.

In my personal experience, LLMs help with:

- answering questions

- generating simple code/scaffolding in a vacuum

At the same time I don't have much success using LLMs to generate code in a simple CRUD application (around 20K LOC).

What I am looking for, is a video showing w/o time lapses/breaks, how an experienced prompt engineer uses an LLM to add a non trivial feature to a code base with at least 20K LOC.

What I am looking for:

- It must be used to add a feature on a bigger code base (>= 20 LOC)

- The added feature cannot be a leaf feature (means it must integrate with the rest of the system at multiple points)

- The prompting has to be less effort/faster than to type the solution in the programming language

- Any programming language/framework is fair game

- Any LLM is fair game

- The code base can be a bigger open source project (since I assume all LLMs were trained on open source projects, this should make it easier for LLMs to perform)
