Module 5: Agent Memory¶
Give your agent memory. Session context tracks the current conversation. Long term preferences persist across conversations.
How it works¶
| Memory type | What it stores | Lifetime |
|---|---|---|
| Session | Every message in the current conversation | Expires after the session ends |
| Long term | User preferences and facts | Persists across conversations |
Cloud setup¶
1. Create an Agent Memory store¶
- In the Redis Cloud console, find Agent Memory in the left sidebar.
-
Click Quick Create.

2. Copy your API key¶
Save this — you won't see it again.

3. Get your Endpoint and Store ID¶
After dismissing the key dialog, find both on the store details page:

4. Configure environment¶
Add to your .env:
MEMORY_API_BASE_URL=<endpoint from step 3>
MEMORY_STORE_ID=<store-id from step 3>
MEMORY_API_KEY=<API key from step 2>
5. Seed long term memories¶
This seeds two facts for the demo patient: "Prefers morning appointments when available" and "Primary care provider is Dr. Sofia Martinez at Downtown Medical."
Exercise¶
Open exercises/healthcare/agent_memory.py
long_term_search_payload(text, owner_id, session_id, limit)¶
This tells Agent Memory how to search for stored user preferences. When a conversation starts, the agent calls this to recall what it knows about the patient.
def long_term_search_payload(self, *, text, owner_id, session_id, limit):
return {
"text": text, # what to search for
"similarityThreshold": 0.2, # how close a match must be
"filterOp": "all", # all filters must match
"limit": limit or 5, # max memories to return
"filter": {
"ownerId": {"eq": sanitize_owner_id(owner_id)}, # scope to this patient
"namespace": {"eq": "healthcare-demo"}, # scope to this app
},
}
Fill in the method body with the dict above.
filterscopes results so each patient only sees their own memoriessanitize_owner_idis already imported at the top of the file
Try it¶
Restart with make dev, then open localhost:3040.
- Ask: "Based on what you know about my preferences, what kind of appointment should I schedule?" — the agent recalls "morning appointments" and your primary care provider
- Ask a follow up: "Can you check my referrals?" — the agent remembers what you just discussed
Verify¶
- Agent recalls seeded preferences ("morning appointments" and "Dr. Sofia Martinez")
- Multi turn conversations maintain context
- Activity panel shows session and long term memory lookups
