DeepSeek Harness vs Claude Code questions
What is the core difference in DeepSeek Harness vs Claude Code?
DeepSeek Harness organizes capability as plugins loaded into profiles, so its surface is whatever you assemble. Claude Code arrives as a coding agent centered on a terminal and a repository, with its own extension mechanism on top.
Which one has more extensions?
Count is the wrong measure. This catalog indexes 236 DSH plugins from GitHub, but what matters is whether the one integration you need exists and is still maintained, which you check per plugin rather than in aggregate.
Can I use both?
Yes, and plenty of teams do, using each for different work. Compare them on one identical task instead of on feature lists, and record setup time and review effort for each.
Which is safer on a work machine?
Neither is safe by default, because both can run commands and read your code. Compare how each asks for permission, what it does without asking, and how you would audit it afterwards.
How do I run a DeepSeek Harness vs Claude Code evaluation?
Put one real task through both with the same repository and the same acceptance criteria. Measure how much you had to correct rather than how quickly the first output appeared.
