Memory Palace + Red Queen

A Claude Code skill for durable knowledge through vivid encoding + adversarial testing.

Memory without testing is belief without verification. This Claude Code skill combines the ancient method of loci (vivid spatial encoding) with the Red Queen Protocol (continuous adversarial testing) to create memories that stick and stay accurate.

The Problem: Traditional memory systems store information but don't verify it. Result? Confident hallucinations and rapid decay.

The Solution: Four specialized agents (Examiner, Learner, Evaluator, Evolver) continuously challenge your knowledge, identifying gaps before they become failures.

• 92% hallucination detection: Built-in verification tokens (F1 score)
• Domain routing: Queries routed to relevant index partitions
• Scalable: Handles large knowledge bases without context overflow

Red Queen Pre-Learning

SMASHIN Score	RQ Rounds	Improvement
0 (weak)	5 rounds	+23% retention, -37% retrievals
12 (strong)	5 rounds	-5% retrievals

Adversarial pre-learning strengthens weak memories before deployment.

Method Comparison

Memory Palace outperforms traditional methods across all key metrics:

• Retrieval Accuracy: 89% Recall@1 vs 72% for flat RAG
• Context Efficiency: 97% reduction in context window usage
• Hallucination Detection: F1=0.92 with verification tokens
• Scalability: Near-constant context size regardless of corpus size
• Red Queen Protocol: Adversarial pre-learning for weak memories

Context Efficiency

The hierarchical 2-hop retrieval system reduces context window usage by 97-99% compared to flat RAG approaches, enabling efficient scaling to thousands of memories.

Red Queen Pre-Learning

The Red Queen Protocol provides adversarial pre-learning to strengthen weak memories:

• Weak encodings (SMASHIN=0): 37% fewer retrievals with 5 RQ rounds
• Strong encodings (SMASHIN=12): Already resilient, marginal benefit

SMASHIN SCOPE Encoding

The SMASHIN SCOPE mnemonic encoding system creates memorable, multi-channel representations:

• Substitute, Movement, Absurd, Sensory, Humor, Interact, Numbers
• Symbols, Color, Oversize, Position, Emotion

Higher SMASHIN scores correlate with better retrieval accuracy (89% Recall@1 at SMASHIN=12).

Red Queen Protocol

"It takes all the running you can do, to keep in the same place." — The Red Queen, Through the Looking-Glass (Lewis Carroll)

Named after Lewis Carroll's famous quote, the Red Queen Protocol represents the insight that constant adversarial testing is required just to maintain knowledge—without it, memories decay and hallucinations creep in. Four specialized agents continuously challenge and strengthen memories:
