Someone just leaked claude code's Source code on X

Went through the full TypeScript source (\~1,884 files) of Claude Code CLI. Found 35 build-time feature flags that are compiled out of public builds. The most interesting ones: Site: https://ccleaks.com **BUDDY** — A Tamagotchi-style AI pet that lives beside your prompt. 18 species (duck, axolotl, chonk...), rarity tiers, stats like CHAOS and SNARK. Teaser drops April 1, 2026. *(Yes, the date is suspicious — almost certainly an April Fools' egg in the codebase.)* **KAIROS** — Persistent assistant mode. Claude remembers across sessions via daily logs, then "dreams" at night — a forked subagent consolidates your memories while you sleep. **ULTRAPLAN** — Sends complex planning to a remote Claude instance for up to 30 minutes. You approve the plan in your browser, then "teleport" it back to your terminal. **Coordinator Mode** — Already accessible via CLAUDE\_CODE\_COORDINATOR\_MODE=1. Spawns parallel worker agents that report back via XML notifications. **UDS Inbox** — Multiple Claude sessions on your machine talk to each other over Unix domain sockets. **Bridge** — claude remote-control lets you control your local CLI from claude.ai or your phone. **Daemon Mode** — claude ps, attach, kill — full session supervisor with background tmux sessions. Also found 120+ undocumented env vars, 26 internal slash commands (/teleport, /dream, /good-claude...), GrowthBook SDK keys for remote feature toggling, and USER\_TYPE=ant which unlocks everything for Anthropic employees.
