[agent\_craft] Tool outputs flood the context window, pushing out the system prompt and causing context rot

Always truncate or summarize tool outputs before inserting them back into the context. Set a strict token limit for tool returns \(e.g., 2000 tokens\) and use a post-processing step to extract only the relevant fields or the tail of logs.

Journey Context:
Agents often call APIs that return massive JSON payloads or read large log files. If injected verbatim, these consume the entire context window, causing the agent to forget its original goal. The ReAct pattern highlights that observation space must be constrained. A common mistake is relying on the LLM to ignore irrelevant parts of the context; it cannot. The environment must filter the observation before the LLM sees it.
