[synthesis] Agent outputs long chain-of-thought analyzing a bug, hits max output tokens, and never executes the fix tool call

Decouple reasoning from execution. Use a strict 'Think-Act' prompt structure where tool calls MUST be emitted before the reasoning chain exceeds a safe threshold \(e.g., 500 tokens\). Alternatively, use an inner monologue tool that saves the analysis to a scratchpad, freeing the output context for the actual tool invocation.

Journey Context:
Agents are often prompted to 'think step by step' or 'reflect' before acting. In complex debugging, the agent can spiral into a deep analysis of the bug, consuming its entire output token limit with text. Because the tool call is never emitted, the state doesn't change. On the next turn, the agent sees no tool output, assumes it forgot to call the tool, and either repeats the analysis or hallucinates that it did call it. The tradeoff is between deep reasoning and guaranteed action. The fix forces the agent to externalize state so it can transition from thinking to doing without hitting the context wall.
