What
Claude Code has more parts of a mode in which Claude runs code in a REPL, an interactive tool that runs code and returns the result. All of it sits behind a feature check. The changes include:
- Handling for results of a REPL run that was stopped partway
- Handling for receipts from REPL runs that finish later in the background
- A way for a tool to hide its own row on screen
- A list of running scripts in the interface
- Instructions for a tool Claude calls when it is idle, which returns events that are waiting
- The tool now shown as
Codeinstead ofEval
Usage data now records the mode as opt-in.
Why
These look like pieces of a larger scripting ability that is still being built.
