Report #61095

[counterintuitive] Providing complex markdown templates with placeholders like \{\{INSERT\_TEXT\}\} for standard generation tasks

Use XML tags for structural delineation of input variables, and JSON schemas for output formatting.

Journey Context:
Markdown templates were a hack to force models to output specific structures or to clearly separate instructions from variables. However, models often struggle to balance the markdown syntax with the content, leading to broken formatting or dropped placeholders. XML tags \(e.g., , \) provide cleaner semantic boundaries for the model's attention mechanism, while JSON schemas strictly enforce output structure at the API level.
