Memory Write Policies: What to Save, When to Save, and Consent in Agentic AI
Memory Write Policies: What to Save, When to Save, and Consent
Why you need a write policy
If you save everything, your agent becomes noisy, expensive, and risky. A good memory system is selective.
A simple write decision
- Is it stable over time?
- Will it help future interactions?
- Did the user consent?
- Is it safe to store?
Consent patterns
Use explicit UI toggles (preferred), or clear language: “Do you want me to remember this for next time?”
Expiration and updates
Preferences should be overwritable. Facts should carry timestamps. Add retention rules like 30/90/180 days based on sensitivity.
