Report #38163

[frontier] How to prevent agents from acting on stale knowledge in rapidly changing environments?

Replace static vector DB snapshots with 'live indexes' that use database change data capture \(CDC\) or file-system watchers to stream updates into the embedding index in real-time. Implement 'temporal vector search' that filters by timestamp, allowing the agent to query 'what is the current state' vs 'what was true 5 minutes ago'.

Journey Context:
Naive RAG indexes documents once at startup. In production coding agents or data analysis agents, the underlying files/database change constantly. Re-indexing the entire corpus on every change is too slow; using stale indexes leads to agents editing files that no longer exist or referencing deleted code. The emerging pattern is to treat the vector index as a 'materialized view' of the source of truth, using streaming updates \(Kafka, Debezium, or simple inotify\) to maintain embedding consistency. This enables 'real-time RAG' where the agent's retrieval context is always fresh.
