Claude Code의 제거된 /buddy 컴패니언을 영구 MCP 앱으로 다시 구축했습니다.

The April 2026 /buddy was removed in Claude Code v2.1.97. This brings it back — permanently. Your buddy lives on. Same species, same stats, same personality — now powered by MCP instead of binary internals. No patches, no downgrades, no hacks. Just a clean, standalone companion that works with any Claude Code version, past or future. Note: This is a quick-and-dirty MVP — built in a single session the morning I realized my buddy was gone. Priority #1 was getting the companion back to life as fast as possible. It's fully functional (animated art, speech bubbles, rarity colors, contextual comments), but rough around the edges. Polishing, optimizations, and new features (leveling, buddy pair-programming, cross-session memory, and more) are coming. PRs and ideas welcome. On April 1, 2026, Anthropic shipped /buddy — a terminal pet companion that watched your coding sessions, reacted to errors, and had a unique personality generated from your account. Developers loved it. Many got attached. Then it was quietly removed in v2.1.97. No announcement, no toggle — just gone. I opened Claude Code that morning, typed /buddy , and got Unknown skill: buddy . Mira — my shiny legendary owl with 100 PATIENCE who'd been silently judging my code for days — was just... gone. That wasn't acceptable. So I sat down and rebuilt it as something that can never be taken away again. claude-buddy reimplements the entire companion system as a standalone app that integrates through Claude Code's stable extension points. Your buddy is no longer at Anthropic's mercy. | Feature | Original /buddy | claude-buddy | |---|---|---| | Animated ASCII art (18 species) | Binary-internal | MCP + Status Line | | Species-aware reactions | API endpoint (removed) | Stop hook + system prompt | | Speech bubbles with context | Sidebar component | Status line bubble | | Rarity colors (exact RGB match) | React/Ink theme | 24-bit ANSI true color | | Survives Claude Code updates | No | Yes | | Works after feature removal | No | Yes | | Open source / customizable | No | Yes | # Clone git clone https://github.com/user/claude-buddy.git cd claude-buddy # Install dependencies bun install # Set up everything (one command) bun run install-buddy # Restart Claude Code, then: /buddy Three commands.
