Afaik the reverse is also true. Some models are trained for specific harness setups so work better/more efficiently in that harness. If you give a model trained on a Read/Write/Bash tool setup a harness with only Bash where it needs to generate shell commands, I'd expect it to perform differently.

Related, there was a small debacle when Claude Code yeeted out a prompt change telling Opus to use Bash for everything. It was speculated it was an optimization to try to make it more efficient by encouraging it to chain a bunch of "tool use" commands into a giant shell command. However, they didn't communicate it clearly and it broke a bunch of setups that expected/hooked tool calls

There's also the (anecdotal?) tradeoff that dumb models tend to do better with smart tools and smart models tend to do better with dumb tools (smart tools -> easier to use but require more context usage for specs, dumb tools -> harder to use but more versatile and save context)
