[synthesis] Agent abandons its initial plan during execution leading to contradictory changes

Decouple planning from execution by storing the plan in a structured, immutable artifact \(e.g., a markdown file or JSON state machine\). Force the execution agent to read the plan file and explicitly update a 'current step' index before every tool call.

Journey Context:
In Plan-and-Solve architectures, the agent generates a brilliant step-by-step plan in step 1, but by step 5, the plan has scrolled out of the context window or been overshadowed by tool outputs. The agent starts improvising, leading to changes that contradict step 1. Simply prompting 'stick to the plan' fails. The synthesis of state machine theory and LLM context decay reveals the plan must be externalized and mechanically tracked, not just memorized in the prompt.
