[synthesis] Agent loses track of original goal after multiple tool calls \(context poisoning\)

Implement a tool-output summarization step or extraction strategy before appending results to the agent's context history, preserving only the signal relevant to the current objective.

Journey Context:
Developers often increase context window size to fix goal drift, but larger contexts increase latency and cost, and still get poisoned by irrelevant details. The real issue is signal-to-noise ratio in the context, not just size. By summarizing or extracting only the relevant fields from tool outputs, the agent maintains a high-signal context and avoids pushing the original goal out of the attention window.
