North Star Build 2.0

Governed autonomy for AI-native software development.

North Star Build (NSB) compiles methodology into enforceable tool instructions. It delivers confidence calibration, autonomy controls, and deterministic anchors across Claude Code, Cursor, and Codex.

Quick Start

npm i -g @nsb/cli

# Initialize governance in a repo
nsb init --profile professional --tools claude,cursor,codex

# Validate configuration
nsb validate

# Regenerate tool instructions
nsb update

CLI binary: northstarbuild (alias: nsb)

What It Generates

After nsb init, your project includes:

.mbf/
  mbf-governance.yaml   # Canonical governance config
  anchors.yaml          # Combined anchors (generated)
  custom-anchors.yaml   # Your custom anchors
CLAUDE.md               # Claude Code instructions
.cursor/rules/mbf.mdc   # Cursor rules
AGENTS.md               # Codex instructions

Governance Model

• Instruction-Based Enforcement (IBE) — governance lives in tool-native instructions
• SSAP — structured self-assessment with confidence thresholds
• Anchors — deterministic risk adjustments for sensitive paths and content

---

Framework Documents

The methodology and technology foundations remain in the original framework set:

• NORTH_STAR_BOOTSTRAP.md — ignition key
• BRIDGE.md — routing layer
• north-star-blueprint/ — HOW to build
• master-build-framework/ — WHAT to build with
