Today, I ran into an issue where I wanted to use repomix to pack a large codebase into a single file to pass to an LLM, but I couldn’t paste the output into any of the UIs I typically use. The React apps all became sluggish as I waited for ~500,000 tokens to paste.
Enter llm.
I solved this problem with a bash one-liner:
llm -m gemini-2.5-pro-preview-05-06 "The provided context is all the code of an old codebase. Analyze this code and come up with high impact, meaningful improvements to make the codebase easier to work with." < repomix.output
The API and subsequent inference took about 85 seconds, and I had my response.
The quality of the results was mixed. There were a few good suggestions, some of which we’d already considered and some that we’re currently implementing. Overall, I’m unsure this is an approach I will reach for very often.
