Lightweight cognitive protection layer for LLM systems

🧠 YecoAI Cognitive Layer

LLMs fail silently. This layer doesn’t.

Anti-loop • Amnesia detection • Semantic stability

Developed by www.yecoai.com

✨ Why do you need it?

When LLMs enter production, they fail in ways that traditional monitoring misses. They loop, they forget context (Amnesia), and they degrade into "word salad".

Critical Failure	What happens?	How we fix it
🔄 Infinite Loops	Model repeats the same token or phrase forever.	Loop Guard detects structural and n-gram repetitions.
😶 Context Amnesia	Model ignores initial instructions or shifts topic.	Keyword Persistence monitors prompt-to-output alignment.
📉 Semantic Drift	Output becomes nonsensical or loses coherence.	Stability Metrics evaluate entropy and word distribution.

📊 Benchmarks & Methodology (v1.0.0)

Engineering Note: These results are derived from our Robust 25-Case Stress Test, specifically designed to simulate production failure modes that traditional LLM monitors often miss.

Methodology

• Stress Dataset: 25 curated edge cases (Loops, Amnesia, Style Drift, False Positive stress tests).
• Execution: Pure Python deterministic evaluation (no LLM-calling-LLM overhead).
• Objective: High-precision detection of catastrophic failures with negligible latency.

Metric	Result	Context
Total Accuracy	96.00%	24/25 edge cases correctly identified.
Loop Detection (F1)	1.00	Zero false negatives on token/phrase loops.
Normal (F1)	0.96	High transparency for valid creative output.
Amnesia (F1)	0.92	Detects context loss within ~0.5ms.
Average RAM	24.95 MB	Minimal footprint for edge/container.
Latency (Avg)	1.76 ms	Real-time protection without user-perceived delay.

🧩 Core Capabilities

• 🔁 Multi-level Loop Detector Analyzes structural patterns, n-grams, and Burstiness (irregular repetitions).
• 🧠 Amnesia Detection Monitors contextual continuity and semantic coherence using Keyword Persistence Tracking.
• 🧯 Semantic Stability Guard Prevents meaning collapse and nonsensical text output using advanced "Word Salad" metrics.
• ⚡ Performance Edge Average RAM usage of only 24.95 MB. Optimized for edge deployment.

🚀 Practical Examples

1. Installation

pip install yecoai-cognitive-layer

2. Protecting an LLM Chatbot (Production Pattern)

This example shows how to use the layer as a "Validator" for a standard LLM response.

from yecoai_cognitive_layer import FeatureEngine, CognitiveModel

# 1. Setup the guards
engine = FeatureEngine()
model = CognitiveModel.load_from_json("weights.json")

def get_safe_llm_response(prompt):
    # Simulate an LLM call (e.g., OpenAI, Anthropic, or Local Llama)
    llm_output = call_your_llm_api(prompt) 
    
    # 2. Cognitive Validation
    vector, features = engine.extract_features(llm_output)
    prediction, scores = model.predict(vector, features)
    
    # 3. Decision Logic
    if prediction == "Loop":
        # If the LLM starts repeating itself, we trigger a retry or a fallback
        return "⚠️ [System Blocked a Loop] Please rephrase your request."
    
    if prediction == "Amnesia" or features['semantic_coherence'] < 0.25:
        # If the response is nonsensical or context is lost
        return "🧠 [Context Loss Detected] I'm having trouble following. Let's restart."

    return llm_output

# Usage
print(get_safe_llm_response("Write a long story about..."))

3. Agent Self-Correction Loop

For autonomous agents, you can use the layer to detect when the agent is "stuck" in a reasoning loop before it consumes too many tokens.

agent_history = []

while agent_running:
    action = agent.think()
    
    _, features = engine.extract_features(action)
    
    if features['repetition_score'] > 0.7 or features['struct_loop_flag'] > 0.5:
        print("🚨 Agent Loop Detected! Injecting 'Break Loop' instruction.")
        agent.inject_system_message("You are repeating yourself. Stop and try a different approach.")
        continue
        
    agent.execute(action)
