 **Auto-Recall:** Before each agent response, relevant memories are automatically injected into the context (up to 1024 tokens). The agent uses past context without needing to call tools.
 
+**Feedback Loop Prevention:** The plugin automatically strips injected memory tags (`<hindsight_memories>`) before storing conversations. This prevents recalled memories from being re-extracted as new facts, which would cause exponential memory growth and duplicate entries.

 Traditional memory systems give agents a `search_memory` tool - but models don't use it consistently. Auto-recall solves this by injecting memories automatically before every turn.
