Claude Code v2.1.323 adds experimental Code Mode
Understand this story
Anthropic releases Claude Code v2.1.323, adding an experimental optional feature Code Mode: when enabled, Claude calls its tools by writing JavaScript, and it can be disabled organization-wide. This version also adds engines["claude-code"] version range validation to plugin.json, and adds type checking for plugin TypeScript hooks modules; when hooks run for a long time in claude -p and SDK sessions, a progress heartbeat is sent every 30 seconds to prevent hosts such as Claude Desktop from judging the turn as hung, but this only takes effect after the host includes this version. In addition, CLAUDE_CODE_AUTO_MODE_MODEL can be used in managed settings for Claude Desktop sessions on third-party providers, and likewise requires Claude Desktop to include this version; CLAUDE_CODE_DISABLE_AGENT_PROGRESS_SUMMARIES has been available since 2.1.318, and setting it to 1 disables subagent progress summaries and their write requests.
