[synthesis] Agent loops derail silently due to context window saturation from verbose tool outputs

Implement aggressive summarization or truncation of tool outputs before appending to the context, and enforce a strict token budget per tool response.

Journey Context:
People often assume the LLM will just 'ignore' irrelevant parts of a large tool output. However, as the context fills with verbose logs \(e.g., full stack traces, directory listings\), the attention mechanism degrades, leading to silent hallucinations or repetitive loops because the agent loses track of the original goal. The synthesis of context-window research and agent-loop dynamics reveals that it's not just about staying under the token limit; attention dilution causes the agent to myopically focus on recent, irrelevant noise. Summarizing at the tool boundary preserves the high-signal intent and prevents the loop from derailing without an explicit error.
