Declarative Prompt-Programming Framework

A Declarative Prompt-Programming Framework is a prompt-programming framework that uses a declarative syntax to express the structure, inputs, outputs, and constraints of LLM interactions while hiding implementation details.

• Context:
  • It can typically represent Prompt Design as structured data rather than imperative code, allowing for more systematic and maintainable prompt management.
  • It can typically use Declarative Syntax (such as YAML, JSON, or custom DSLs) to express what the LLM interaction should accomplish without specifying how it is executed.
  • It can typically provide Prompt Specification documents that are parsed and executed by a runtime interpreter.
  • It can typically support Schema Validation for both input and output to reduce prompt failures and ensure data consistency.
  • It can typically enable Modular Reuse through import mechanisms and include directives for prompt components.
  • It can typically abstract Model-Specific Details, creating a model-agnostic representation of declarative prompt-programming intentions.
  • It can typically enforce Output Structure through schema definitions, constraints, or type systems.
  • ...
  • It can often include Templating Directives (using systems like Jinja2 or Liquid) for dynamic content generation.
  • It can often implement Control Flow Constructs such as declarative prompt-programming loops, declarative prompt-programming conditionals, and declarative prompt-programming function definitions.
  • It can often provide Type Checking for declarative prompt-programming variables to ensure data integrity.
  • It can often support Multi-Step Workflows by declarative prompt-programming chaining or declarative prompt-programming orchestration.
  • It can often enable Collaborative Prompt Development through its human-readable format and defined structure.
  • It can often facilitate Prompt Versioning to track declarative prompt-programming evolution.
  • It can often include Error Handling Mechanisms that manage LLM output failures through retry logic and fallback strategy.
  • It can often provide Validation Feedback Loops where invalid outputs trigger corrective reprompts.
  • ...
  • It can range from being a Simple Declarative Prompt-Programming Framework to being a Complex Declarative Prompt-Programming Framework, depending on its declarative prompt-programming feature complexity.
  • It can range from being a Domain-Specific Declarative Prompt-Programming Framework to being a General-Purpose Declarative Prompt-Programming Framework, depending on its declarative prompt-programming application scope.
  • It can range from being a Lightweight Declarative Prompt-Programming Framework to being a Comprehensive Declarative Prompt-Programming Framework, depending on its declarative prompt-programming integration capability.
  • It can range from being a Specialized Declarative Prompt-Programming Framework to being a Universal Declarative Prompt-Programming Framework, depending on its declarative prompt-programming model compatibility.
  • It can range from being a Single-Call Declarative Prompt-Programming Framework to being a Multi-Step Declarative Prompt-Programming Framework, depending on its declarative prompt-programming orchestration complexity.
  • It can range from being a Code-Embedded Declarative Prompt-Programming Framework to being a Standalone Declarative Prompt-Programming Framework, depending on its declarative prompt-programming host language relationship.
  • ...
  • It can integrate with Retrieval-Augmented Generation Pipelines for structured document processing.
  • It can connect to LLM API for standardized model interaction.
  • It can support Agent Orchestration Systems for multi-step workflow management.
  • It can interface with Version Control Systems for declarative prompt-programming history tracking.
  • It can incorporate External Knowledge Sources via declarative prompt-programming retrieval mechanisms.
  • It can work with Validation Tools for declarative prompt-programming quality assurance.
  • It can integrate with CI/CD Pipelines for automated prompt testing and prompt deployment.
  • It can connect to Output Validation Systems for LLM output reliability enhancement.
  • It can support Safe Guardrail Integration for LLM response filtering and harmful content prevention.

  • Ad-hoc Prompt Design Approaches, which lack formal structure, schema validation, and reusable components that characterize declarative prompt-programming frameworks.
  • Template-Only Systems, which provide basic text substitution without the full declarative prompt-programming capabilities like schema validation and control flow.
  • Model-Specific Frameworks that tightly couple prompt design to specific LLM implementations, lacking the model-agnostic abstraction of declarative prompt-programming frameworks.
  • Raw API Interactions where prompt text is directly passed to LLM API without intermediate representation or declarative structure.
  • Hardcoded Prompt Systems that embed prompt strings directly in application code, preventing separation of concerns and prompt versioning.
