Memory Persistence
Part of Agent Skills™ by googleadsagent.ai™
Description
Memory Persistence enables AI agents to maintain knowledge across sessions, transforming stateless inference calls into stateful, continuously improving systems. Without persistence, every new session starts from zero — the agent must re-learn user preferences, re-discover codebase patterns, and repeat mistakes it has already corrected. Memory Persistence solves this by implementing hooks that save critical context at session end and reload it at session start, creating the illusion of continuous memory.
This skill is built on the production memory system powering Buddy™ at googleadsagent.ai™, which uses Cloudflare KV as a persistent memory store. After each conversation, Buddy™ extracts entities (campaigns, metrics, user preferences, decisions made), summarizes the session, and stores the result keyed by user and session. On the next conversation, the most relevant memories are retrieved and injected into context, giving Buddy™ the ability to reference prior analyses, respect stated preferences, and build on previous decisions.
The memory system operates at three granularities: entity-level memory (individual facts like "user prefers conservative bidding"), session-level memory (summarized conversations), and pattern-level memory (recurring behaviors like "this account always overspends on branded terms"). Each granularity serves different retrieval patterns and has different storage and freshness requirements.
