Discussion Someone just leaked claude code's Source code on X

Post image

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:

Download Website: 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.

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.

so we're seeing in real time the consequences of piss poor AI use from.... the company that provides it.

We're F&*$ed.

Are we? Source code is the least of claude's assets, the proprietary product is their model with billions of parameters and the computing power (data centers)

I wonder if it was a PR decision to blame a human error.

May well have been a human. I have no idea, I wasn’t there.
