[synthesis] Agent hallucinates non-existent tools or arguments to force alignment with a rigid, pre-written plan

Use dynamic replanning instead of static plan execution; inject the available tool schemas directly into the reasoning step where the plan is being executed, not just at the beginning.

Journey Context:
In Plan-and-Solve architectures, the agent creates a step-by-step plan, then executes it. If Step 2 requires a tool that doesn't quite match the plan's wording, the agent will often hallucinate a tool name or parameter that sounds right rather than deviating from the plan. The plan acts as a rigid constraint on the agent's attention. The agent prioritizes narrative consistency with its past self over factual consistency with its environment. Allowing the agent to revise the plan at every step prevents this forced alignment.
