Sigstack — Vibe Coder's AI Development Stack

Your buddy's complete guide to my AI-assisted development setup

Last Updated: March 2026 — v4.1 "Marlin"

Welcome to Sigstack — my complete Claude Code configuration for shipping software with AI. This repo contains everything you need to replicate my vibe coding setup across macOS, Linux, and Windows.

Quick Start

# Clone this repo
git clone https://github.com/willsigmon/sigstack.git ~/.sigstack

# Run the setup script
cd ~/.sigstack && ./setup.sh

The Stack

Primary Interface: Claude Code CLI

All development happens through Claude Code in iTerm2/Ghostty. On the Sigmachines network, every Claude Code session runs on SigServe (Mac Studio M2 Max) as the central brain.

Remote access (new in v4.1):

• Claude Web → MCP Gateway connector (Tailscale Funnel)
• Claude Desktop → mcp-remote over HTTPS (auto-configured)
• Claude Code → SSH + tmux (cc alias from any machine)
• iMessage → Marlin Router (always-on dual-LLM chat)
• Phone → +1 (844) 719-3335 (Twilio voice)

Alternative editors:

• VS Code + Claude Extension — Great for beginners
• Cursor — AI-first IDE
• Zed — Fast, Rust-based, Claude built-in

Terminal: iTerm2 / Ghostty

# Install Ghostty on macOS
brew install ghostty

Token-Saving Hooks

These hooks automatically prevent wasteful operations:

Hook	Blocks/Warns
Read Validator	Files >100KB, lockfiles, minified, .xcodeproj
Bash Validator	Commands touching node_modules, .git, DerivedData
Model Enforcer	Blocks Opus model (cost optimization)
Write Validator	Warns on files >50KB
Glob Validator	Warns on **/* patterns
Grep Limiter	Suggests head_limit when not specified
Repeated Read Detector	Suggests caching on repeated file reads

Tasks

Tasks are the built-in primitive for tracking complex projects across sessions and subagents.

# Start Claude with a shared task list
CLAUDE_CODE_TASK_LIST_ID=my-project claude

Tools: TaskCreate, TaskGet, TaskUpdate, TaskList
