Report #66640

[counterintuitive] Chaining 10 tiny, single-task prompts instead of one comprehensive prompt for complex coding tasks

Batch related instructions into a single, well-structured prompt \(using XML tags\) to maintain context and reduce latency/error accumulation.

Journey Context:
Early agents over-decomposed tasks due to context window limits. With modern 128k\+ context windows and stronger instruction-following, micro-chaining introduces state-management bugs, context loss, and latency. Macro-prompting with clear XML tags outperforms because the model can cross-reference instructions within the same context window, avoiding the error multiplication inherent in long sequential pipelines.
