UnverifiedPrompt engineering has evolved from simple instruction writing into a systematic methodology, and structured prompts (such as those using XML tags or Markdown hierarchies) yield more consistently stable output quality than free-text formats.67% similarUnverifiedStructured prompts that use XML tags or Markdown to clearly separate instructions, context, and output requirements are the best practices officially recommended by Anthropic.67% similarUnverifiedHigh-quality prompts should reference existing patterns and file paths in the codebase, provide additional context such as logs and error messages, and clearly express design intent and constraints.62% similarVerifiedEffective code-generation prompts typically need to contain three levels: a constraint layer (tech stack, framework version, code style specifications), a structural layer (page skeleton, component hierarchy), and a semantic layer (business meaning, data logic).59% similarUnverifiedCode embedding needs to capture information at three levels: lexical (variable names, keywords), syntactic (AST structure, control flow), and semantic (the actual functional intent of the code).57% similar
