About this episode

Claude Code 2.1.280 adds a long-awaited fix for MCP tool descriptions that were silently capped at 2,048 characters, plus a new environment variable to raise or lower the limit as needed. The episode also covers the tradeoffs of larger prompts, a Write tool validation patch, and quality-of-life fixes like improved modal exits and better scrolling.
