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

Show HN: I made an open source, keyboard-first AI writing assistant
Hey everyone!
I just "vibecoded" Spellbound MVP in a day—it's an AI writing assistant that lets you hit a shortcut for instant translations or writing tips, making workflow automation super easy.
First time using Electron for cross-platform apps. A lot of fun
It’s open source. Check it out: https://github.com/stanlee000/spellbound
PS: And yes, I used Spellbound for this post
Would love your feedback
