I tend to be sceptical when it comes to LLM based coding tools but many people seem to be raving about huge productivity gains which I wouldn’t mind as well.

However when trying cc it left me vey disappointed. For context I’m working on a relatively greenfield rust project and gave it tasks that I would consider appropriate for a junior level colleague like:

- change the return type of a trait and all it’s impls

- refactor duplicate code into a helper function

- replace some of our code with an external crate

it didn’t get any of them correct and took a very long time. Am I using the tool wrong?

How are you using cc or other agentic tools?

Totally get where you’re coming from. I had a similar first impression, it felt slow, and the output wasn’t great unless I hand-held it through every step.

What helped me was shifting how I use it. I don’t treat it like a junior dev anymore, I treat it more like a second brain. For example:

I use Claude Code to explore options before I commit to a design. I’ll ask it “what are 3 ways to abstract this logic?” and sometimes that alone gives me a better direction.

It’s pretty good at turning rough notes or comments into starter code or test cases. That saves time on boilerplate.

If I feed it a clean, self-contained chunk of code and ask for a targeted change (e.g., “convert this to async”), it often nails it. But yeah, across a codebase, not so much.
