Prompt Template Development with Variables
Prompt Templates — parameterized prompt templates where variables are substituted at runtime. Allow reusing prompt structure for different inputs, managing versions centrally, testing variations.
Basic Templates
Python f-strings (simple), Jinja2 (powerful with conditionals), LangChain PromptTemplate (integrations).
Hierarchical Templates: base templates for classifier, extractor, summarizer, qa. Manager class to select and format templates.
Dynamic Prompt Builder: assembles prompts dynamically based on context. Includes: context docs, examples, constraints, output schema.
Template Versioning and Storage
Store templates in YAML (recommended for team work). Track version, description, variables, evaluation examples.
