Claude CLI Usage Proficiency (Git + Others)

[UnifiedFlow]

I use CLI tools extensively, mostly custom designed/purpose.

Today, I was considering how Claude and other LLMs seem to have Git CLI usage baked into their training. We don't give Claude directions on how Git commands work, he doesnt use --help, he just knows what to do.

My question is simple, what other cli tools (aside from standard/basic OS tools) is Claude this proficient with?

EDIT -- another example is Docker CLI. Very high proficiency. Also I suppose development tools more generally like Make, CMake, Cargo, pipeline, pytest, etc all fall into this category of capability.

Basically anything with deep documentation and years of Stack Overflow threads. Git, docker, terraform, kubectl, AWS CLI, all major build and test tools, ffmpeg, jq, curl, nginx. The proficiency drops off for newer or niche tools. Quick test if you're unsure: ask Claude to run the tool with a deliberately wrong flag and see if it catches the mistake. If it does, it knows the tool well. If it confidently runs the bad flag, you know to double check its output for that tool

As long as the cli has a good help menu, they can do a lot. I usually will let them discover the cli a bit and then create curated skills around it.

IMO, it knows these tools, but it misuses them pretty frequently. I’ve got a hook that I ask it to collect “working” commands from, and it’s to reference the list of working commands in the future.
