It seems unwise not to implement sandbox measures just because the chance of misuse has gotten lower.

It also doesn't allow leaving an audit trail of plans and decisions (by default, anyway). Most of my mutating prompts look like "Propose a plan for change X and write to file Y" and "Execute steps M-N from file Y".

RE the article: I don't think it's obvious why this process is worth following until you find your time and attention wasted. Conversationally-building is the express train to waste. I'm not sure why you would even be talking to claude if you don't understand what you want to build.

Do you really trust it with a production code base or database? Telling it not to make changes feels an awful lot like "Make no mistakes". I also like how Plan mode on Codex asks clarifying questions. I'm in management now so I've used Work more than Code lately.

I agree. Plan mode came about because earlier models were loose cannons, doing what they pleased. Today's models follow instructions better enough to not need a separate mode. However, there is still value in using a separate, smarter model for planning than execution, and persisting it for auditing on completion.

If you do use plan mode you might like https://plannotator.ai/

I typically converse with the default model to point the plan in the right direction, then have it iterate with a smarter reviewer to find flaws until the plan file is converged.
