BuildShitNow

Autonomous software factory for Claude Code. Give it a project idea, it researches, plans, executes, reviews, and ships -- all in one command. Zero human orchestration required.

Install

npx buildshitnow@latest

That's it. No config, no setup, no dependencies to install.

Quick Start

1. Start Claude Code in any project directory
2. Run /bsn:build [describe what you want to build]
3. Watch it research, plan, execute, review, and ship

Commands

| Command | What it does | |---------|-------------| | /bsn:build [idea] | Start building from scratch | | /bsn:next | Resume where you left off | | /bsn:status | Check project progress |

What Happens Under the Hood

• Research -- Analyzes your idea, explores similar projects, identifies technical requirements
• Planning -- Builds a phased roadmap with dependency ordering and wave-based parallelization
• Plan Review -- Adversarial checker verifies each plan before execution begins
• Execution -- Writes code task-by-task with atomic commits and automatic deviation handling
• Scope + Architecture Review -- CEO-level scope check and engineering architecture review
• QA + Security -- Browser smoke tests (for web projects) and grep + LLM security audit
• Verification -- Goal-backward check that what was built matches what was requested

Model Profiles

| Profile | Best for | Cost | |---------|----------|------| | quality | Production launches, complex systems | Highest (all Opus) | | balanced | Most projects (default) | Moderate (Opus plans, Sonnet executes) | | budget | Prototypes, experiments | Lowest (Sonnet plans, Haiku executes) |

Set in .planning/config.json under model_profile.

Requirements

• Claude Code (latest)
• Node.js >= 20
