I think a link would have been far more helpful than "RTFM". Especially for those of us reading this exchange outside of the line of fire.

Don't put the onus (Opus!) on me! Just a dad approach to helping. If there's enough time to writ prose about the problem you could at least rtfm first!

If you know something is covered by the documentation it's useful to provide a link, especially if that documentation is difficult to find.

(I couldn't find that documentation when I went looking just now.)

Step 1: https://docs.anthropic.com

Step 2: Type 'Allowed Tools'

Step 3: Click: https://docs.anthropic.com/en/docs/claude-code/sdk/sdk-headl...

Step 4: Read

Step 5: Example --allowedTools "Read,Grep,WebSearch"

Step 6: Profit?

The original question was about this:

> allow zoned access enforcement within files. I want to be able to say "this section of the file is for testing", delineated by comments, and forbid Claude from editing it without permission.

So you've completely misunderstood what the discussion is about...

Maybe rtft ? Read the fucking thread.

I think you missed a critical step: 1.5: know that "allowed tools" is the correct incantation required to summon the relevant documentation; which, at least to me, is not obvious at all in the context of the OP.
