Desktop-managed sessions were blocking the first visible token on slow or failing regular MCP connections, which made the UI feel much slower than direct bin runs. This keeps partial assistant streaming enabled for desktop sessions and moves regular MCP connection work off the critical path only for sdk-url startup. Constraint: Desktop sdk-url sessions must preserve chat responsiveness even when local MCP endpoints fail or hang Rejected: Leave MCP startup fully blocking in sdk-url mode | first visible token stayed several seconds behind direct CLI runs Confidence: high Scope-risk: moderate Reversibility: clean Directive: Keep blocking MCP startup for plain -p sessions unless you re-measure first-turn latency and tool availability tradeoffs Tested: bun test src/server/__tests__/conversation-service.test.ts src/server/__tests__/conversations.test.ts; same-prompt timing comparison for direct bin vs sdk-url session path Not-tested: Immediate first-turn availability of slow regular MCP tools in desktop sdk-url sessions
Claude Code Haha
A locally runnable version repaired from the leaked Claude Code source, with support for any Anthropic-compatible API endpoint (MiniMax, OpenRouter, etc.). Beyond the full TUI, we've also completed Computer Use (macOS / Windows), built a GUI desktop app, and enabled full remote control via Telegram / Feishu.

Quick Start
1. Install Bun
# macOS / Linux
curl -fsSL https://bun.sh/install | bash
# macOS (Homebrew)
brew install bun
# Windows (PowerShell)
powershell -c "irm bun.sh/install.ps1 | iex"
On minimal Linux images, if you see
unzip is required, runapt update && apt install -y unzipfirst.
2. Install Dependencies and Configure
bun install
cp .env.example .env
# Edit .env with your API key — see docs/en/guide/env-vars.md for details
3. Start
macOS / Linux
./bin/claude-haha # Interactive TUI mode
./bin/claude-haha -p "your prompt here" # Headless mode
./bin/claude-haha --help # Show all options
Windows
Prerequisite: Git for Windows must be installed.
# PowerShell / cmd — call Bun directly
bun --env-file=.env ./src/entrypoints/cli.tsx
# Or run inside Git Bash
./bin/claude-haha
4. Global Usage (Optional)
Add bin/ to your PATH to run from any directory. See Global Usage Guide:
export PATH="$HOME/path/to/claude-code-haha/bin:$PATH"
5. Desktop Development
If you are developing or testing the desktop/ frontend, start both the API server and the desktop frontend.
5.1 Start the API server
cd /Users/nanmi/workspace/myself_code/claude-code-haha
SERVER_PORT=3456 bun run src/server/index.ts
Optional health check:
curl http://127.0.0.1:3456/health
5.2 Start the desktop frontend
cd /Users/nanmi/workspace/myself_code/claude-code-haha/desktop
bun run dev --host 127.0.0.1 --port 2024
Then open:
http://127.0.0.1:2024
5.3 Notes
- If port
3456is already occupied by an old server process, runlsof -nP -iTCP:3456 -sTCP:LISTEN, find the PID, thenkill <PID>. - For chat testing, create a fresh session and re-select a real working directory.
- If an old session points to a deleted directory, the server will return
Working directory does not exist. That is separate from whether the API server is running.
