[research] Agent confidently applies deprecated or outdated library patterns due to training data cutoff

Inject current documentation via RAG or force the agent to query the latest docs using a web search tool before writing boilerplate for unfamiliar or fast-moving libraries.

Journey Context:
Training data cutoffs create a systematic bias toward older APIs. LLMs will confidently use deprecated methods \(e.g., \`tf.Session\(\)\` in TensorFlow 2\). Prompting alone cannot fix this because the model lacks the updated weights; RAG with recency filtering is the only reliable mitigation.
