-The router node evaluates each task and routes to one of 7 agent nodes via conditional edges. The connector node uses Composio tools for external service interactions.
+The retriever embeds Adam's memory files once and caches vectors to `.cache/embeddings.json` (mtime-keyed; only changed files re-embed). Each run picks the top-3 most relevant memories and surfaces them in the CLI output before the route line.
+
+The router uses Pydantic structured output (`RouteDecision`) and returns an explicit `"unknown"` route when no agent fits — no silent fallback. All LLM invocations are wrapped with retry-on-transient-error.

 ## Usage
 
 ```bash
-# Full execution — routes and runs the task
+# Full execution — retrieves memory, routes, and runs the task
 python3 run.py "What is the LangGraph checkpoint API?"
 
-# Route-only — prints which agent would handle the task
+# Route-only — retrieves memory and prints the agent that would handle the task
 python3 run.py --route-only "Review this code for security issues"
 ```

+
+## Memory retrieval
+
+The retriever reads `~/.claude/projects/-Users-adammoussa-Documents-repositories/memory/*.md` (skipping the `MEMORY.md` index), embeds each file once with `text-embedding-3-small`, and caches the vectors to `.cache/embeddings.json`. On subsequent runs:
+
+- Only files whose mtime changed are re-embedded.
+- Top-3 memories by cosine similarity are injected as system context into both the router and the agent.
+- Retrieved names are printed as the first line of every run so bad retrieval is visible.
+- Retrieval is **read-only.** The orchestrator never writes back to the memory store.
+
+If retrieval fails (network, missing key), the run continues with no memory context and logs the failure into the message trail.
