Claude Code 2.1.323 adds experimental Code Mode
Claude Code 2.1.323 adds an experimental Code Mode in which Claude writes JavaScript to call its tools, which changes how the agent carries out multi-step tasks.
Claude Code version 2.1.323 is out, according to a post on X by Alex (@alexmichael). The post summarizes the release in five short items.
The main addition is Code Mode, an experimental option. In this mode, Claude writes JavaScript to call its tools instead of calling them one by one. The post does not say how to turn it on, which tools it covers or whether it improves speed or reliability.
The other changes listed:
- Usage limits: When a user runs out of usage credits, a new menu lets them stop, switch to credits or upgrade.
- Context default: Models that Claude Code doesn't recognize now get a 1M-token context window by default instead of 200K.
- Session messaging: Sessions on the same machine can now message each other 100,000 times without the user stepping in. The previous limit was about 20.
- Artifacts: Artifacts now accept .docx uploads.
The post gives no further technical detail, documentation links or rollout timing. It also doesn't say whether Code Mode is available on all plans.
