Check a module against the golden module

openkraft check payments

Check Report: payments vs tax (golden)

  Score: 65/100

  Missing Files:
    ✗ {module}/application/service.go
    ✗ {module}/application/service_test.go

  Missing Methods:
    ✗ NewService in service.go
    ✗ Process in service.go

Check all modules

openkraft check --all

Scoring Categories

Category	Weight	What it measures
Architecture	25%	Hexagonal layers, dependency direction, module boundaries
Conventions	20%	Naming consistency, file naming, receiver naming
Patterns	20%	Error handling, interface compliance, constructor patterns
Tests	15%	Test coverage ratio, test file presence
AI Context	10%	CLAUDE.md, .cursorrules, AGENTS.md, .openkraft/
Completeness	10%	File manifest coverage, structural completeness

MCP Server (AI Agent Integration)

OpenKraft includes a Model Context Protocol server that lets AI agents (Claude Code, Cursor) understand your codebase structure and fix issues.

Claude Code Setup

Add to your project's .mcp.json:

{
  "mcpServers": {
    "openkraft": {
      "command": "openkraft",
      "args": ["mcp", "serve"]
    }
  }
}

Available MCP Tools

Tool	Description
openkraft_score	Score a project's AI-readiness
openkraft_check_module	Check a module against the golden blueprint
openkraft_get_blueprint	Get the structural blueprint from the golden module
openkraft_get_golden_example	Get example code from the golden module
openkraft_get_conventions	Get detected naming conventions
openkraft_check_file	Check a specific file for issues

How It Works

Developer runs: openkraft score → "47/100"
Developer runs: openkraft check payments → "missing 9 files, 3 methods"
Developer opens Claude Code with OpenKraft MCP connected
Claude Code asks OpenKraft: "what's missing in payments?" → gets structured answer
Claude Code generates the missing code following golden module patterns
Developer runs: openkraft score → "82/100"

1. Score — Diagnose your codebase with 6 weighted categories
2. Check — Prescribe exactly what's missing vs your best module
3. MCP — Bridge to AI agents that can fix the issues

Architecture

OpenKraft uses hexagonal architecture with pure Go AST analysis — no LLM, no WASM, fully deterministic.
