# 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

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 asx-api-keyheader (standard Anthropic format)ANTHROPIC_AUTH_TOKEN→ sent asAuthorization: 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
Key Fixes vs. Original Leaked Source
| Symptom | Root Cause | Fix Applied |
|---|---|---|
| TUI never starts | Entry script routed no-args to recovery CLI | Restored cli.tsx full entry path |
| Startup hangs forever | verify skill imports missing .md files; Bun text loader hangs | Created stub .md files |
--print hangs | filePersistence/types.ts missing | Created type stub |
--print hangs | ultraplan/prompt.txt missing | Created resource stub |
| Enter key does nothing | modifiers-napi native pkg absent; isModifierPressed() throws, breaking handleEnter | Added try-catch around modifier check |
| Setup skipped entirely | preload.ts auto-set LOCAL_RECOVERY=1 bypassing all init | Removed that default |

| Layer | Technology |
