> LORE is a **plugin-based code archaeology engine** for TypeScript projects. It parses your AST, maps dependencies, detects circular deps, tracks async chains, scores type safety, and feeds architectural intelligence to AI coding assistants through the **Model Context Protocol (MCP)**.

**Built by [EliotShift](https://github.com/EliotShift) · Battle-tested on 16 real-world projects · 100% pass rate.**

---

## Why LORE?

AI coding assistants write fast, but they lack **architectural memory**. They can't remember:

- Which files are tightly coupled
- Where circular dependencies live
- Which types are spreading across boundaries
- Which files change too often (hotspots)
- What the architectural layers are

LORE solves this by giving your AI assistant a **deep understanding of your codebase architecture** — through CLI analysis and MCP server integration.

## Features

### 13 Analyzers

| # | Analyzer | What It Does |
|---|----------|-------------|
| 1 | **AST Parser** | Full TypeScript/TSX parsing with ts-morph + regex hybrid |
| 2 | **Dependency Graph** | Maps all imports, exports, re-exports across your project |
| 3 | **Circular Dependency Detector** | Finds cycles and ranks them by severity |
| 4 | **Dependency Direction Checker** | Enforces layer rules (e.g., no controller → DB imports) |
| 5 | **Shannon Entropy** | Complexity scoring per file (simple → very-complex) |
| 6 | **Hotspot Analysis** | Git-churn detection — files that change too often |
| 7 | **Import Impact Analyzer** | Shows the blast radius of every import |
| 8 | **Type Safety Scorer** | Grades your `any` usage, explicit types, strictness |
| 9 | **Hidden Coupling Detector** | Finds implicit dependencies through shared types |
| 10 | **AI Recommendations** | Prioritized fix suggestions (P0–P3) |
| 11 | **Tooling Config Checker** | Validates ESLint, Prettier, tsconfig settings |
| 12 | **Breaking Change Detector** | Flags high-risk deprecation patterns |
| 13 | **Architectural Gap Finder** | Identifies missing abstractions and patterns |

## Quick Start

### Install

```bash
npm install -g lore-mcp
```

### CLI Usage

```bash
# Analyze current project
lore

# Analyze a specific project
lore ./my-typescript-project

# Check environment and auto-fix
lore doctor --fix

# Watch for changes
lore watch --filter src/

# Diff from last baseline
lore diff
```

### MCP Integration (Claude Desktop)

Add this to your Claude Desktop config:

**macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`
**Linux:** `~/.config/Claude/claude_desktop_config.json`
**Windows:** `%APPDATA%\Claude\claude_desktop_config.json`

```json
{
  "mcpServers": {
    "lore": {
      "command": "npx",
      "args": ["-y", "lore-mcp"]
    }
  }
}
```

Or if installed globally:

```json
{
  "mcpServers": {
    "lore": {
      "command": "lore",
      "args": ["mcp"]
    }
  }
}
```

Restart Claude Desktop, then ask:

> "Analyze my project architecture" → LORE runs `analyze_architecture`
> "What are the circular dependencies?" → LORE runs `get-violations`
> "Which files are hotspots?" → LORE runs `get-hotspots`
> "What are the AI recommendations?" → LORE runs `get-recommendations`

### Plugin System

LORE uses a **plugin-based architecture** — every analyzer is a plugin:

```typescript
interface LorePlugin {
  name: string;
  version: string;
  analyze(context: AnalysisContext): Promise;
}
```

Built-in plugins include: `circular-deps`, `coupling-matrix`, `dep-direction`, `entropy`, `gaps`, `hidden-coupling`, `hotspot`, `import-impact`, `middleware-chain`, `breaking-changes`, `type-safety`, `tooling-config`, `ai-recommendations`.

---

## How It Works

1. **Parse** — LORE parses all `.ts`/`.tsx` files using a hybrid ts-morph + regex parser
2. **Build Graph** — Constructs a dependency graph with typed edges (import, type-ref, decorator, async-chain, implements, extends)
3. **Run Plugins** — 13 analyzers run in parallel through the plugin pipeline
4. **Score** — Computes health scores (type safety, tooling, architecture, overall 0–100)
5. **Recommend** — AI engine generates prioritized suggestions (P0 critical → P3 nice-to-have)
6. **Serve** — Results available via CLI output, MCP tools, or SARIF format
