Anthropic's Claude Code 2.1.323 adds experimental JavaScript tool-calling mode

By PulseAugur Editorial · [1 sources] ·

Anthropic has released Claude Code 2.1.323, introducing an experimental "Code Mode" that allows the model to execute multiple tool calls in a single pass by generating JavaScript. This new functionality aims to improve efficiency for multi-step tasks compared to sequential tool calls. The release also includes enhanced plugin version compatibility checks and a change to the /security-review feature, which now prompts for confirmation before execution. Despite the feature's potential, public documentation for Code Mode is not yet available. AI

IMPACT This update enhances Claude's ability to execute multi-step tasks more efficiently by batching tool calls via JavaScript, potentially speeding up complex workflows.

RANK_REASON This is a minor update to an existing model, not a new frontier release.
