RecallBricks Agent Runtime

Universal cognitive runtime for AI systems - persistent identity, continuous memory, and self-improving intelligence.

What is RecallBricks Runtime?

RecallBricks is Layer 3 of the RecallBricks cognitive stack - a universal runtime that sits between any LLM and your application to provide:

• Persistent Identity - Stable personality and behavior across all sessions
• Continuous Memory - Automatic context loading with zero manual management
• Self-Improving Intelligence - Learns from every interaction via the Metacognition Engine
• Universal Compatibility - Works with Anthropic, OpenAI, Gemini, Ollama, and local models
• Self-Reflection - Built-in metacognition with automatic reflection and reasoning

This is not just memory infrastructure. This is cognitive infrastructure.

Quick Start

Installation

# TypeScript/JavaScript
npm install @recallbricks/runtime

# Python
pip install recallbricks

30-Second Example

import { AgentRuntime } from '@recallbricks/runtime';

const agent = new AgentRuntime({
  agentId: 'sales_bot',
  userId: 'customer_123',
  llmProvider: 'anthropic',
  llmApiKey: process.env.ANTHROPIC_API_KEY,
  apiKey: process.env.RECALLBRICKS_API_KEY,
});

// Chat with automatic context loading
const response = await agent.chat("What did we discuss last time?");
console.log(response.response);
// Agent remembers everything - no manual memory management!

// Optional: Trigger self-reflection
const reflection = await agent.reflect();
console.log(reflection.insights);

That's it. The runtime handles:

• Loading relevant context from past conversations
• Injecting agent identity and behavioral rules
• Calling the LLM with enriched context
• Validating response for identity leakage
• Saving conversation for future reference

Key Features

1. Automatic Context Loading

No manual memory management required:

// Day 1
await runtime.chat("I'm working on a machine learning project");

// Day 30 - different session
await runtime.chat("Can you remind me what I was working on?");
// Agent: "You were working on a machine learning project..."

The runtime automatically:

• Loads recent conversations
• Retrieves relevant memories
• Includes predicted context
• Optimizes token usage

2. Persistent Identity

Your agent maintains stable identity across all sessions:

// Bad: "I'm Claude, an AI assistant made by Anthropic"
// Auto-corrected: "I'm SalesBot, your sales assistant"

Identity validation detects and corrects:

• Base model references (Claude, ChatGPT, etc.)
• Generic AI assistant language
• Inconsistent behavior
• Identity contradictions

3. Universal LLM Support

Switch providers without code changes:

// Anthropic Claude
llmProvider: 'anthropic'

// OpenAI GPT
llmProvider: 'openai'

// Google Gemini
llmProvider: 'gemini'

// Ollama (local)
llmProvider: 'ollama'

// Custom local models
llmProvider: 'local'

4. Multi-User Isolation

Each user gets separate memory and context:

const alice = new AgentRuntime({ userId: 'alice', ... });
const bob = new AgentRuntime({ userId: 'bob', ... });

// Alice and Bob have completely isolated conversations

5. Self-Reflection & Metacognition

Agents can analyze their own behavior and improve:

// Trigger manual reflection
const reflection = await agent.reflect();
console.log(reflection.insights);
// ["User prefers concise answers", "Topic focus: machine learning"]

// Explain reasoning (Chain of Thought)
const trace = await agent.explain("Why did you recommend that?");
console.log(trace.steps);
console.log(trace.conclusion);

6. Continuous Learning

Every interaction feeds the Metacognition Engine:

User interaction
      ↓
Auto-save to API
      ↓
Metacognition Engine
      ↓
Pattern detection
      ↓
Improved predictions

Integration Options

1. TypeScript/JavaScript SDK

import { AgentRuntime } from '@recallbricks/runtime';

const runtime = new AgentRuntime({
  agentId: 'my_bot',
  userId: 'user_123',
  llmApiKey: 'sk-...',
});

const response = await runtime.chat('Hello!');

2. Python SDK

from recallbricks import AgentRuntime

runtime = AgentRuntime(
    agent_id='my_bot',
    user_id='user_123',
    llm_api_key='sk-...'
)

response = runtime.chat('Hello!')

3. REST API

# Start server
npm run build
PORT=3000 node dist/adapters/api/server.js

# Use from any language
curl -X POST http://localhost:3000/chat \
  -H "Content-Type: application/json" \
  -d '{"message": "Hello!"}'

4. MCP (Claude Desktop)

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "recallbricks": {
      "command": "node",
      "args": ["/path/to/dist/adapters/mcp/server.js"],
      "env": {
        "RECALLBRICKS_AGENT_ID": "my_bot",
        "RECALLBRICKS_USER_ID": "user_123",
        "RECALLBRICKS_API_URL": "https://recallbricks-api-clean.onrender.com"
      }
    }
  }
}

Note: No Anthropic API key needed! Claude Desktop already has Claude running. The MCP server only loads/saves context from RecallBricks API.
