# RecCall: Universal Context Management System

**Rec**ord and **Call** context shortcuts across AI IDEs and environments. Now featuring **ML-powered context generation**, **semantic search**, and **unified context management**.

> **🚀 New in v2.0**: Universal Context Management System with ML intelligence, hybrid search, and dynamic context generation from conversations.

## 🏗️ Architecture

RecCall has been refactored into a modular plugin-based architecture:

- **Core Engine**: Business logic, storage, repository management, caching
- **Platform Adapters**: CLI, MCP, VSCode, Warp, Perplexity, Sora
- **Dependency Injection**: Enterprise-ready IoC container
- **Telemetry**: Structured logging and performance monitoring

## 🚀 Features

### Universal Context System (v2.0)

**Three Context Types:**
- **Static Contexts**: Pre-defined templates and guidelines
- **Dynamic Contexts**: ML-generated from conversations (auto-summarization, topic extraction, code references)
- **Hybrid Contexts**: Static templates enhanced with ML insights

**ML-Powered Intelligence:**
- Conversation summarization
- Code reference extraction
- Semantic embeddings for search
- Topic/keyword extraction

**Hybrid Search:**
- Keyword search (fast, exact matches)
- Semantic search (meaning-based similarity)
- Combined results for comprehensive discovery

### Universal Commands
- **rec**: Record a shortcut with context/instructions
- **call**: Call (retrieve) stored context by shortcut name
- **list**: List all stored shortcuts
- **update**: Update an existing shortcut
- **delete**: Delete a shortcut (idempotent operation)
- **purge**: Purge all shortcuts (with confirmation)
- **search**: Search shortcuts by content

### Context Commands (v2.0)
- **context create**: Create static contexts
- **context get**: Retrieve contexts by name or ID
- **context search**: Hybrid search (keyword + semantic)
- **context list**: List all contexts with filters
- **context delete**: Remove contexts
- **context stats**: View usage analytics

### Repository Commands
- **install**: Install a recipe from the repository
- **list-repo**: List available recipes from repository
- **search-repo**: Search recipes in repository
- **reload-starter-pack**: Reload starter pack recipes

### Multi-Platform Support
- **🖥️ Cursor IDE**: MCP server integration with core engine

## 📦 Installation

### Quick Setup
```bash
curl -sfL https://reccaller.ai/install.sh | sh -
```

### Manual Installation
   ```bash
npm install -g reccall
```

## 🎯 Usage

### CLI - Shortcuts (v1.0)
```bash
# Record a shortcut
reccall rec react-component "Create React components with TypeScript, proper props, and hooks"

# Call a shortcut
reccall call react-component

# List all shortcuts
reccall list

# Install from repository
reccall install sync-main
```

### CLI - Universal Context System (v2.0)
```bash
# Create a static context
reccall context create my-template \
  --content "# My Template\n\nGuidelines..." \
  --source global \
  --tags development \
  --category guides

# List all contexts
reccall context list

# Search contexts (hybrid: keyword + semantic)
reccall context search "API testing"

# Get a context
reccall context get my-template

# View statistics
reccall context stats

# Create dynamic context from conversation (via API/MCP)
# Automatically generates summary, topics, and embeddings
```

### MCP (Cursor IDE)
```json
{
  "mcpServers": {
    "reccall": {
      "command": "reccall-mcp",
      "args": []
    }
  }
}
```

**By default, RecCall MCP server runs both stdio (for Cursor) and HTTP (for browser extensions) transports.**

#### HTTP MCP Server (for Browser Extensions)

The HTTP MCP server runs on `http://localhost:3000/mcp` by default, enabling browser extensions (Perplexity, Sora) to connect via HTTP.

**CLI Options:**
```bash
# Default: both stdio and HTTP enabled
reccall-mcp

# Custom HTTP port
reccall-mcp --http-port 8080

# Only HTTP (for testing browser clients)
reccall-mcp --http-only

# Only stdio (Cursor only)
reccall-mcp --stdio-only

# Disable HTTP
reccall-mcp --no-http
```

**Testing HTTP endpoint:**
```bash
curl -X POST http://localhost:3000/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'
```

### Browser Extensions
- **Perplexity**: Inject context into AI search queries
- **Sora**: Use video generation prompts with context shortcuts

## 🔧 Core Engine API

```typescript
import { createCoreEngine } from 'reccall/core';

const engine = await createCoreEngine();
await engine.initialize();

// Record a shortcut
await engine.record('my-shortcut' as ShortcutId, 'My context instructions');

// Call a shortcut
const context = await engine.call('my-shortcut' as ShortcutId);

// List shortcuts
const shortcuts = await engine.list();

// Install from repository
await engine.installRecipe('https://contexts.reccaller.ai/' as RepositoryUrl, 'sync-main' as ShortcutId);
```

  res.send(telemetryManager.exportPrometheusMetrics());
});
```

## 🔌 Plugin Development

### Creating a Platform Adapter
```typescript
export class MyPlatformAdapter implements IPlatformAdapter {
  readonly platform = 'my-platform';
  readonly capabilities = {
    canRecord: true,
    canCall: true,
    canList: true,
    canUpdate: true,
    canDelete: true,
    canPurge: true,
    supportsRepository: true
  };

  async initialize(context: PlatformContext): Promise<void> {
    // Platform-specific initialization
  }

  async recordShortcut(): Promise<{ shortcut: ShortcutId; context: string } | null> {
