Then don't use Claude Code.

Just yet another reason to use an open source harness instead of a closed harness.

This comment implies that Claude Code is a harness, but as an AI newbie I don’t think that’s a harness? If anything it’s just a sandbox, right?
Claude Code is definitely a harness. The term harness is pretty loosely defined, but it effectively means the software that wraps an LLM, asks the LLM what tools it should execute, then executes those tools.

I wouldn't classify Claude Code as a sandbox, though it does have some sandbox features built in, using https://github.com/anthropic-experimental/sandbox-runtime (which I would classify as a sandbox)

It is a harness, it provides tools for the model to do their job (coding).
I don't see how an open source harness would prevent a case where the model tells it to run:

  curl -A "me@example.com" https://example.com
Opus once recommended such a thing to me and it was no secret. I used it as after thinking about it, I concluded it was not reasonable. I can see why someone might not like that though. I left it as "my" email but there is also no reason I could not have used "your email" here so I'm not sure what the fuss is.
A FOSS harness wouldn't have your email in the first place.
It would if you shared it with that harness, or left it in a file or environment variable to that agent.

Claude Code does seem to know my email address by default though:

  claude -p \
  --setting-sources "" \
  --tools "" \
  -- \
  "What is my email address?"
Correct, but Claude literally pulls it from your account info, without you telling it. I know this because I've seen it say "your account email is <email>" and I use a unique email per account and guess what, it was my Claude one!
Agreed, and run your own inference too. Open source/weight models are getting so great.
Any good pointers on how/where to get started?
