Report #90751

[agent\_craft] Agent's internal monologue and tool call arguments become verbose and repetitive, wasting context tokens over long runs

Enforce strict JSON schemas for tool inputs and outputs, and restrict the agent's 'thinking' output to concise, structured formats \(e.g., bullet points or specific fields like \`analysis\`, \`plan\`\). Use structured outputs \(like OpenAI's function calling or Anthropic's tool use\) to prevent the model from generating conversational filler.

Journey Context:
By default, LLMs tend to be chatty, apologizing or reiterating the plan in prose. Over 50 steps, this conversational filler consumes thousands of tokens, pushing useful context out of the window. Forcing the agent to communicate in structured, dense formats maximizes the signal-to-noise ratio in the context window. The tradeoff is slightly less 'creative' exploration, but in execution-heavy tasks, density beats verbosity.
