Anthropic pulled the Buddy Mode feature from Claude Code in version 2.1.97, barely after it had a chance to land. The changelog entry is blunt: "REMOVED: System Prompt: Buddy Mode — Removed the coding companion personality generator for terminal buddies."
Buddy Mode was a system prompt layer that gave Claude Code a distinct companion personality in the terminal - think a more conversational, character-driven coding assistant rather than a neutral tool. It never made it into official documentation or release notes in any meaningful way, which suggests this was an experimental feature that shipped prematurely or failed internal review.
Feature removals this fast usually mean one of two things: the implementation had unexpected side effects on model behavior, or Anthropic decided the personality framing conflicted with how they want Claude Code positioned. A coding tool with a "buddy" persona raises real questions about whether that tone holds up under the pressure of debugging production issues at 2am. Probably the right call to yank it, even if the idea has some appeal for developers who find bare CLI tools cold. Whether it comes back in a more refined form is unclear.
