Unclear The second tool name the rules now cover is not stated.

What

Permission rules let you deny a tool or require Claude Code to ask you before it runs. The check that applies these rules to a REPL tool, one that runs code for artifacts, now matches a list of two tool names instead of just that one. A deny or ask rule on one of the two names can now take effect for the other, with a message saying the tool runs code the same way and a rule denies or asks before it.

Why

If you have rules for code-running tools, they may now block or prompt for a tool they did not cover before.
