Overview

Metaprompt is a template language for LLM prompt automation, reuse and structuring, with support for writing prompts with prompts.

It adds a number of syntactic constructs to plaintext prompts, that get expanded at run time, producing textual output:

  • variables
  • conditionals
  • LLM calls
  • function calls
  • etc.

Project status

!!! This is an early work-in-progress !!!

Not all of the described features have been implemented.

The repository README will give you more details.

Use cases

Templating

MetaPrompt's basic use case is substituting parameter values instead of variable names embedded in a prompt:

Write me a poem about [:subject] in the style of [:style]

Prompt rewriting

Prompt rewriting is a technique of asking an LLM to create/modify/expand an LLM prompt.

  • Dynamically crafting task-specific prompts based on a set of high level principles
  • Modifying prompts to increase accuracy
  • Securing inputs from prompt injection attacks and for content moderation
  • Selecting the most suitable model for a task

Quick example:

[$ You are an LLM prompt engineer.
  Improve this prompt by adding specific details:
  [:prompt]
]

Prompt structuring

A module system and a package system enable parameterized prompt reuse and publishing.

Knowledge base maintenance

Organize your knowledge base in the form of multiple documents loaded conditionally on demand.
