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.

Destructive-command warning reads the tool input

Not switched on
Useful3 Signal3
Permissions Notable not in their notes

The destructive-command warning now reads the real command, but it stays off unless the feature flag is on.

The Bash destructive-command warning is fixed to inspect real input, but sits behind tengu_destructive_command_warning, which falls back to false.

Feature flag
tengu_destructive_command_warning Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

This account: off · anonymous baseline: off · compiled default in v2.1.223: on

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

What

The Bash permission UI now checks the actual command being run rather than a rendered display string, so the destructive-command warning fires when it should.

Details
  • two Bash permission surfaces take the command from e.input.command when it is a string
  • the memoization dependency list was widened to include the input, so the check re-evaluates when the input changes
  • gated on tengu_destructive_command_warning, fallback false
Evidence

tengu_destructive_command_warning

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