Code Diff Tools

Discussions center on the advantages of using diff tools to review code changes, particularly suggesting LLMs generate or use diffs instead of direct text comparisons, and recommending tools like GitHub diffs, Diffchecker, and IDE integrations.

It's nice to ask for diffs, then you can see exactly what's changing.

Wouldn't it be better to ask the LLM to use a diff tool instead of asking it look at the text directly?

Appreciate your input! Totally agree—a quick diff would make this way more useful. Would you prefer a natural language summary of the changes, or an actual code diff?

sameI need something like a web diff

Surely not diffs offered by the git ecosystem?

+ it shows you a diff with the ability to revert individual changes in code

I like the github diff view, definitely makes it easier to spot the more minute differences when testing smaller prompt changes.

Maybe someone could make a tool to generate such a diff automatically.

They need to implement a git diff...
