AgentSoul — Framework-Agnostic Agent Persistence Platform

The memory backbone for production AI agents. Works with any LLM framework.

---

What is AgentSoul?

AgentSoul is a standalone, monetizable infrastructure product that solves the hardest problem in agent development: persistent, reliable, portable agent memory.

Unlike chatbots that forget after each session, AI agents in production need:

• Long-term memory of customers, interactions, and patterns
• Memory portability (dev Mac → customer RPi5 → fleet of devices)
• Zero drift (consolidation + decay prevents hallucination)
• Framework flexibility (works with Hermes, LangGraph, CrewAI, AutoGen, etc.)
• Compliance-ready (audit trails, GDPR delete, encryption)

AgentSoul provides all of this in <10 lines of Python code.

Core Features

1. Universal Memory Interface (SDK)

One Python class, three backends: SQLite (standalone), REST (cloud), PocketBase (local server).

from agentsoul import AgentSoul

# Initialize once, works everywhere
soul = AgentSoul.from_rest(
    url="http://localhost:5001",
    agent_id="clerk_001",
    token="your_api_token"
)

# Store memory
soul.remember("customer", "cust_001", {
    "name": "Alice",
    "payment_style": "reliable",
    "contact": "sms"
})

# Retrieve with automatic consolidation
context = soul.recall("customer", "cust_001", consolidate=True)

# Inject into agent
system_prompt = soul.get_system_context("cust_001")

2. Importance-Based Decay (Not just time)

Memories decay based on business signals, not just age:

• Recent interactions get higher weight
• Frequently-mentioned facts persist longer
• High-value customers = higher memory weight
• Explicit feedback signals boost importance

Result: Agents stay focused on what matters.

3. Soul Portability (Export/Import)

Move a complete agent soul with one command:

# On Mac (dev)
artifact = soul.export_soul(passphrase="secure_123")
# Save artifact for transfer to RPi5

# On RPi5 (production)
soul_prod.import_soul(artifact, "secure_123")
# Complete state instantly available

4. System Prompt Injection

Pre-loaded context before every agent interaction:

You are serving customer_001.

CONSOLIDATED MEMORY:
- Reliability: highly reliable (95%)
- Prefers: SMS, morning
- Service types: HVAC repair, filter replacement
- Notes: Always pays on time

Respond naturally and helpfully.

5. Production-Ready Packaging

• REST API with Bearer token auth
• Docker support for cloud/Kubernetes
• RPi5 one-liner deployment
• PocketBase integration (local SQLite server)
• Audit trails for compliance

Quick Start

1. Install AgentSoul

git clone https://github.com/agentsoul/agentsoul
cd agentsoul
pip install -e .

2. Initialize Database

python -m agentsoul.persistence.schema
# Creates SQLite tables

3. Start REST API (optional)

python -m agentsoul.adapters.rest_api
# Listening on http://127.0.0.1:5001

4. Use in Your Agent

from agentsoul import AgentSoul

soul = AgentSoul.from_sqlite(
    db_path="/path/to/db.db",
    agent_id="my_agent"
)

# Store memory
soul.remember("entity", "user_123", {"age": 30, "role": "buyer"})

# Recall with consolidation
memory = soul.recall("entity", "user_123")

# Get system prompt
prompt = soul.get_system_context("user_123")
