Cognitive Memory Runtime for AI Agents: bounded state, belief revision, commitment gate

CILO

Cognitive Memory Runtime for AI Agents.

---

Every AI memory system today is a database with a search API.
They store text. Return nearest vectors. Accuracy drops to 50% after 30 days.
Contradictions accumulate. Stale facts persist. There is no control.

CILO is different.

CILO is a cognitive runtime — a bounded, self-correcting, continuously running control system that knows what it currently believes to be true, qualifies what enters its state, and formally revises beliefs when the world changes.

pip install mcilo[local]

Note: PyPI package is mcilo. Python import is cilo. This follows the standard Python convention (e.g. pip install Pillow → import PIL).

Quickstart (60 seconds)

# 1. Start PostgreSQL with pgvector + TimescaleDB
docker compose up -d

# 2. Install
pip install mcilo[local]

# 3. Copy config
cp .env.example .env

import asyncio
from cilo import CiloClient

async def main():
    async with CiloClient() as client:
        # Store a memory
        await client.add("User prefers JAX over PyTorch", user_id="u1")

        # Retrieve with hybrid 4-signal search
        results = await client.search(
            "What ML framework does the user prefer?",
            user_id="u1"
        )
        for r in results.results:
            print(f"[{r.score:.2f}] {r.memory.content}")

asyncio.run(main())

The Cognitive Runtime (Level 3)

from cilo import CiloClient, CognitiveOrchestrator

async def main():
    async with CiloClient() as client:
        async with CognitiveOrchestrator(client, user_id="u1") as orch:

            # THINK — routes to the right memory types automatically
            ctx = await orch.think("What does this user prefer for ML?")
            # ctx.prompt_injection → inject into your LLM system prompt

            # OBSERVE — process any event, routes everywhere automatically
            await orch.observe("user_message", "I just switched from TF to JAX")

            # ACT — record outcome, learning happens automatically
            await orch.act("suggested JAX", success=True)

            # REFLECT — consolidation + health check + staleness verification
            report = await orch.reflect()
            print(report["health"])

asyncio.run(main())

What Makes CILO Different

1. Bounded State — Memory That Doesn't Drift

Every competitor's memory grows linearly with conversation turns. More turns → more noise → hallucinations accumulate → accuracy dies.

CILO's Compressed Cognitive State (CCS) has a fixed schema. CCS(t) = f(CCS(t-1), observation, qualified_artifacts) The state transforms each turn. It never grows.

turn 1:      state = 48 fields  ✓
turn 100:    state = 48 fields  ✓
turn 10,000: state = 48 fields  ✓

2. The Commitment Gate — Only Truth Enters

CILO's Commitment Gate (𝒬) runs 8 rules on every artifact before it enters the state:

Rule	What it checks
R1 Decision Relevance	Does this affect the current decision?
R2 Constraint Safety	Does this contradict a hard constraint?
R3 Confidence ≥ 0.3	Is this reliable enough?
R4 Schema Compliance	Does it fit the CCS schema?
R5 Temporal Validity	Is this still true?
R6 No Higher-Conf Contradiction	Does the state already know better?
R7 No Injection Pattern	Is this a prompt injection attempt?
R8 Affective Alignment	Is this compatible with current mode?

3. Belief Revision — What Does the Agent Currently Believe?

Most systems store what was ever said. CILO knows what is currently believed to be true.

from cilo.beliefs import BeliefRevisionSystem

bs = BeliefRevisionSystem()
bs.revise("User works at Google", confidence=0.95, source="user_message")
# Automatically supersedes "User works at startup" (lower confidence)

beliefs = bs.currently_believes()  # always-consistent active belief set

CILO is built on one insight: memory is a control problem, not a storage problem.
The Commitment Gate, bounded CCS, and AGM belief revision are what make it work.
