[architecture] Agent forgets its own plan halfway through a multi-step task

Maintain an explicit, mutable scratchpad or working-memory artifact inside the prompt, and rewrite it after every step. Do not rely on the model to implicitly track progress across turns.

Journey Context:
Without a written plan, LLMs drift. In long tasks they lose track of subgoals, repeat completed steps, or skip prerequisites. The ReAct pattern showed that giving the model a 'thought → action → observation' loop with a visible scratchpad dramatically improves multi-step reasoning. The scratchpad is not just for the user; it is memory that the model reads and updates each turn. The anti-pattern is hiding state in code variables and expecting the model to infer progress from prior messages. Modern implementations \(chain-of-thought, ReAct, OpenAI functions/Anthropic tool use\) all converge on the same idea: externalize working memory into the prompt as structured text.
