[synthesis] Agent reasoning quality drops as external API payloads silently inflate

Implement strict payload size limits or summarization layers on tool responses before they enter the agent's context window, and monitor the ratio of input tokens to output reasoning tokens.

Journey Context:
If an external API \(e.g., a Jira ticket fetcher or log scanner\) starts returning larger payloads due to a schema change or data accumulation, the agent doesn't fail. Instead, it spends a disproportionate amount of its context window and reasoning capacity just parsing the bloated input. It then outputs shallow, poorly reasoned actions because it hit its compute limit processing the input. The agent's output is valid, but lacks depth. Monitoring API latency won't catch this; you must monitor input token ratios.
