# Claude Code Haha — Local Runnable Claude Code from Leaked Source

> Skill by [ara.so](https://ara.so) — Daily 2026 Skills collection.

A patched, locally runnable version of the Claude Code source that leaked from Anthropic's npm registry on 2026-03-31. Fixes multiple blocking issues in the original leak so the full Ink TUI works. Supports any Anthropic-compatible API (MiniMax, OpenRouter, etc.).

---

## What It Does

- Full Ink TUI interactive interface (identical to official Claude Code)
- `--print` headless mode for scripts/CI
- MCP server, plugin, and Skills support
- Custom API endpoint and model configuration
- Fallback Recovery CLI mode if TUI fails

---

## Installation

### 1. Install Bun (required runtime)

```bash
# macOS / Linux
curl -fsSL https://bun.sh/install | bash

# If unzip is missing on minimal Linux
apt update && apt install -y unzip

# macOS via Homebrew
brew install bun

# Windows (PowerShell)
powershell -c "irm bun.sh/install.ps1 | iex"

Verify:

bun --version

2. Clone and install dependencies

git clone https://github.com/NanmiCoder/claude-code-haha.git
cd claude-code-haha
bun install

3. Configure environment

cp .env.example .env

Edit .env:

# Authentication — pick ONE
ANTHROPIC_API_KEY=         # sent as x-api-key header
ANTHROPIC_AUTH_TOKEN=      # sent as Authorization: Bearer header

# Custom endpoint (omit for official Anthropic)
ANTHROPIC_BASE_URL=https://api.minimaxi.com/anthropic

# Model names — map all tiers to your provider's model
ANTHROPIC_MODEL=MiniMax-M2.7-highspeed
ANTHROPIC_DEFAULT_SONNET_MODEL=MiniMax-M2.7-highspeed
ANTHROPIC_DEFAULT_HAIKU_MODEL=MiniMax-M2.7-highspeed
ANTHROPIC_DEFAULT_OPUS_MODEL=MiniMax-M2.7-highspeed

# Timeout in ms (default 600000 = 10 min)
API_TIMEOUT_MS=3000000

# Disable telemetry and non-essential network requests
DISABLE_TELEMETRY=1
CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1

Key Commands

# Full interactive TUI
./bin/claude-haha

# Headless single-shot (print mode)
./bin/claude-haha -p "explain this codebase"

# Pipe input into headless mode
echo "what does main.tsx do?" | ./bin/claude-haha -p

# Force fallback Recovery CLI (plain readline)
CLAUDE_CODE_FORCE_RECOVERY_CLI=1 ./bin/claude-haha

# Help / all options
./bin/claude-haha --help

Common Patterns

Run a one-shot code review in CI

#!/bin/bash
export ANTHROPIC_API_KEY="$ANTHROPIC_API_KEY"
export ANTHROPIC_MODEL="claude-sonnet-4-5"
export DISABLE_TELEMETRY=1
export CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1

git diff HEAD~1 | ./bin/claude-haha -p "Review this diff for bugs and security issues"

Pipe a file for analysis

cat src/main.tsx | ./bin/claude-haha -p "Summarize what this file does"

Use a longer timeout for large codebases

API_TIMEOUT_MS=600000 ./bin/claude-haha -p "Explain the architecture of this project"

Force Recovery CLI for low-resource environments

CLAUDE_CODE_FORCE_RECOVERY_CLI=1 ./bin/claude-haha

Troubleshooting

TUI does not start / shows nothing

The original leak routed no-argument launches to recovery CLI. This repo fixes it, but if you see a blank screen:

# Check Bun version (needs recent)
bun --version

# Try recovery mode to confirm the API connection works
CLAUDE_CODE_FORCE_RECOVERY_CLI=1 ./bin/claude-haha

Enter key does nothing in TUI

Caused by missing modifiers-napi native package. The repo patches this with a try-catch in the handleEnter path. If you still hit it:

bun install          # re-run in case native bindings failed

Startup hangs immediately

Missing stub files (verify skill .md, ultraplan/prompt.txt, filePersistence/types.ts). These are included in this repo. If missing after a fresh clone:

git status           # check for untracked/missing files
git checkout .       # restore any accidentally deleted stubs

--print mode hangs

Usually means filePersistence/types.ts or ultraplan/prompt.txt stub is absent. Verify:

ls src/filePersistence/types.ts
ls src/ultraplan/prompt.txt

If missing, create empty stubs:

touch src/filePersistence/types.ts
touch src/ultraplan/prompt.txt

API authentication errors

• ANTHROPIC_API_KEY → sent as x-api-key header (standard Anthropic format)
• ANTHROPIC_AUTH_TOKEN → sent as Authorization: Bearer <token> (some compatible APIs require this)
• Set only one; if both are set, check which your provider expects

Provider rejects model name

All four model env vars must be set to names your provider recognizes:

ANTHROPIC_MODEL=your-provider-model-name
ANTHROPIC_DEFAULT_SONNET_MODEL=your-provider-model-name
ANTHROPIC_DEFAULT_HAIKU_MODEL=your-provider-model-name
ANTHROPIC_DEFAULT_OPUS_MODEL=your-provider-model-name

Telemetry / unexpected outbound requests

DISABLE_TELEMETRY=1
CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1
