[research] LLM provides outdated information as if it is currently true \(Temporal Drift\)

Always inject the current date into the system prompt and require the agent to perform a live web search for any query involving recent events, changing statistics, or current software versions.

Journey Context:
LLMs have a training cutoff. They will confidently state that 'React 16 is the latest version' or provide expired API keys because that was true during training. Prompting with the current date helps slightly, but the only reliable fix is to route time-sensitive queries to a search tool rather than parametric memory. Agents must treat temporal facts as inherently volatile.
