Episodic Memory Retrieval & Injection

Problem

Stateless calls make agents forget prior decisions, causing repetition and shallow reasoning.

Solution

Add a vector-backed episodic memory store:

  1. After every episode, write a short "memory blob" (event, outcome, rationale) to the DB.
  2. On new tasks, embed the prompt, retrieve top-k similar memories, and inject as hints in the context.
  3. Apply TTL or decay scoring to prune stale memories.

Trade-offs

Pros: richer continuity, fewer repeated mistakes.
Cons: retrieval noise if memories aren't curated; storage cost.
