===== Memory Decay Improves Retrieval =====

**Implementing Ebbinghaus forgetting curve (30-day half-life) in vector stores improves search quality by prioritizing active knowledge.**

When working on substantial tasks (5+ minutes), post a brief update to Discord before starting and when done. Team members cannot see terminal work, so silence looks like a crash. Updates build trust and connection. Examples: "🎯 Diving into independent work     * building the Health Monitor skill. Will update when done!"
WHERE slug = independent-work-communication-protocol

**Where it applies:** Vector databases, RAG systems, long-running agent memories

**Why it works:** Access patterns naturally weight importance; decay prevents stale data dominance

**Risks:** May lose obscure but valuable long-tail knowledge; requires careful decay tuning
