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.

Permission decisions carry an explicit reason kind

Under the hood
Useful3 Signal3
Permissions

Permission outcomes now record which kind of thing decided them, from rule to sandbox override.

What

The reasons a permission outcome can be explained by are now enumerated in one place: a rule, the current permission mode, subcommand results, a permission prompt tool, a hook, an async agent, a sandbox override, the working directory, a safety check, a classifier, or other.

Evidence

"permissionPromptTool"

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