[synthesis] Agent fails mid-execution because initial plan was too abstract and lacked error handling

Enforce a plan-as-you-go paradigm where the agent only outlines the immediate next step and the high-level goal, rather than generating a deeply nested, multi-step plan upfront.

Journey Context:
A common pattern \(derived from CoT\) is to have the agent write a detailed step-by-step plan before acting. However, in dynamic environments \(like coding\), step 3 often depends on the output of step 1. If the plan is too detailed, the agent rigidly tries to follow it even when step 1 fails or reveals unexpected constraints. The agent gets lost trying to map reality to its flawed plan. Shifting to a plan-as-you-go \(or reactive\) approach trades upfront coherence for adaptability, significantly reducing catastrophic drift when early steps fail.
