+# Claude Code Haha
+
+
中文 | English
+
+A **locally runnable version** repaired from the leaked Claude Code source, with support for any Anthropic-compatible API endpoint such as MiniMax and OpenRouter.
+
+> The original leaked source does not run as-is. This repository fixes multiple blocking issues in the startup path so the full Ink TUI can work locally.
+
+
+
+
+
+## Features
+
+- Full Ink TUI experience (matching the official Claude Code interface)
+- `--print` headless mode for scripts and CI
+- MCP server, plugin, and Skills support
+- Custom API endpoint and model support
+- Fallback Recovery CLI mode
+

+
+## Quick Start
+
+### 1. Install Bun
+
+This project requires [Bun](https://bun.sh). If Bun is not installed on the target machine yet, use one of the following methods first:
+
+```bash
+# macOS / Linux (official install script)
+curl -fsSL https://bun.sh/install | bash
+```
+
+If a minimal Linux image reports `unzip is required to install bun`, install `unzip` first:
+
+```bash
+# Ubuntu / Debian
+apt update && apt install -y unzip
+```
+
+```bash
+# macOS (Homebrew)
+brew install bun
+```
+
+```powershell
+# Windows (PowerShell)
+powershell -c "irm bun.sh/install.ps1 | iex"
+```
+
+After installation, reopen the terminal and verify:
+
+```bash
+bun --version
+```
+
+### 2. Install project dependencies
+
+```bash
+bun install
+```
+
+### 3. Configure environment variables
+
+Copy the example file and fill in your API key:
+
+```bash
+cp .env.example .env
+```
+
+Edit `.env`:
+
+```env
+# API authentication (choose one)
+ANTHROPIC_API_KEY=sk-xxx # Standard API key via x-api-key header
+ANTHROPIC_AUTH_TOKEN=sk-xxx # Bearer token via Authorization header
+
+# API endpoint (optional, defaults to Anthropic)
+ANTHROPIC_BASE_URL=https://api.minimaxi.com/anthropic
+
+# Model configuration
+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 milliseconds
+API_TIMEOUT_MS=3000000
+
+# Disable telemetry and non-essential network traffic
+DISABLE_TELEMETRY=1
+CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1
+```
+
+### 4. Start
+
+```bash
+# Interactive TUI mode (full interface)
+./bin/claude-haha
+
+# Headless mode (single prompt)
+./bin/claude-haha -p "your prompt here"
+
+# Pipe input
+echo "explain this code" | ./bin/claude-haha -p
+
+# Show all options
+./bin/claude-haha --help
+```
+
+---
+
+## Environment Variables
+
+| Variable | Required | Description |
+|------|------|------|
+| `ANTHROPIC_API_KEY` | One of two | API key sent via the `x-api-key` header |
+| `ANTHROPIC_AUTH_TOKEN` | One of two | Auth token sent via the `Authorization: Bearer` header |
+| `ANTHROPIC_BASE_URL` | No | Custom API endpoint, defaults to Anthropic |
+| `ANTHROPIC_MODEL` | No | Default model |
+| `ANTHROPIC_DEFAULT_SONNET_MODEL` | No | Sonnet-tier model mapping |
+| `ANTHROPIC_DEFAULT_HAIKU_MODEL` | No | Haiku-tier model mapping |
+| `ANTHROPIC_DEFAULT_OPUS_MODEL` | No | Opus-tier model mapping |
+| `API_TIMEOUT_MS` | No | API request timeout, default `600000` (10min) |
+| `DISABLE_TELEMETRY` | No | Set to `1` to disable telemetry |
+| `CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC` | No | Set to `1` to disable non-essential network traffic |
+
+---
+
+## Fallback Mode
+
+If the full TUI has issues, use the simplified readline-based interaction mode:
+
+```bash
+CLAUDE_CODE_FORCE_RECOVERY_CLI=1 ./bin/claude-haha
+```
+
+---
+
+## Fixes Compared with the Original Leaked Source
+
+The leaked source could not run directly. This repository mainly fixes the following issues:
+
+| Issue | Root cause | Fix |
+|------|------|------|
+| TUI does not start | The entry script routed no-argument startup to the recovery CLI | Restored the full `cli.tsx` entry |
+| Startup hangs | The `verify` skill imports a missing `.md` file, causing Bun's text loader to hang indefinitely | Added stub `.md` files |
+| `--print` hangs | `filePersistence/types.ts` was missing | Added type stub files |
+| `--print` hangs | `ultraplan/prompt.txt` was missing | Added resource stub files |
+| **Enter key does nothing** | The `modifiers-napi` native package was missing, `isModifierPressed()` threw, `handleEnter` was interrupted, and `onSubmit` never ran | Added try/catch fault tolerance |
+| Setup was skipped | `preload.ts` automatically set `LOCAL_RECOVERY=1`, skipping all initialization | Removed the default setting |
+
