Report #63061

[synthesis] Reasoning chain exhaustion causing abrupt hallucinated shortcuts after 20\+ correct steps

Implement 'forced tool use checkpoints' every N reasoning steps \(e.g., every 10 steps\) - the agent must validate current state against external source via tool call before continuing, breaking the pure reasoning chain and preventing internal consistency checks from drifting.

Journey Context:
'Chain of Thought' prompting fails at scale because the model tries to compress the growing context; forcing external grounding prevents the model from 'giving up' and taking shortcuts when the reasoning chain becomes too long to maintain in working memory.
