DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Confined sessions accept permissions only from their own command line

Under the hood
Useful3 Signal4
Permissions

A confined session ignores permission grants from tools or plans, honoring only its startup flags.

What

A session running in a "confined" mode now refuses permission grants that arrive through a tool or plan response, logging them instead of applying them. Such a session can only be granted permissions by the flags it was started with.

Details
  • Both an allow permission decision and an allowing permission-request result are discarded.
  • What switches this mode on beyond the evaluation context is not visible in the build.
Evidence

a confined session takes grants only from its command line

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
