Aegis Memory

Aegis Memory is an open-source, self-hostable context engineering layer for production AI agents. It provides content security, integrity verification, and trust hierarchy — plus persistent, semantic memory that survives context window resets.

​
The Problem

Every AI agent framework promises memory. Few deliver. 
# What happens today
agent.chat("I'm John, a Python developer")
# ... context window resets ...
agent.chat("What's my name?")  # "I don't know your name"
After analyzing 200+ production agent deployments, we found 40-80% fail due to memory coordination issues—not model capability.
ProblemReality
Context loss mid-taskAgents forget what they learned
No shared stateMulti-agent teams can’t coordinate
Memory bloatEverything saved, nothing useful retrieved
Session boundariesLong tasks restart from zero

​
The Solution

Aegis Memory provides:
1

Content Security

4-stage pipeline: input validation, PII scanning, injection detection, LLM classification
2

Integrity & Trust

HMAC-SHA256 tamper detection, OWASP 4-tier trust hierarchy, cryptographic agent binding
3

Context Quality

ACE patterns — self-improving agents that learn what works (voting, reflections, playbooks)
4

Multi-Agent Coordination

Scoped memory sharing with structured handoffs and access boundaries

​
Quick Example

from aegis_memory import AegisClient

client = AegisClient(api_key="your-key")

# Store a memory
client.add(
    content="User prefers dark mode and Python",
    agent_id="assistant",
    user_id="john_123"
)

# Later, retrieve relevant context
memories = client.query(
    "What are John's preferences?",
    user_id="john_123"
)
# Returns: "User prefers dark mode and Python"
