Key point

The feature allows multiple tool calls in a single pass, reducing context resends and increasing effective output within existing limits.

Claude Code v2.1.323 adds an experimental feature called Code Mode.
Code Mode executes a chunk of JavaScript to run several tool calls in parallel within a single pass.
This reduces the number of round trips and context resends, as every turn previously resends the whole conversation.
The feature is off by default and only works in interactive terminal sessions.
Users can enable it by setting the environment variable CLAUDE_CODE_EXPERIMENTAL_CODE_MODE=1.
