How to Manage a Prompt Library

Define purpose, sources, version, and evaluation criteria for recurring legal work.

In recurring legal work, the model is not the only factor that shapes the result. A prompt library makes task definitions visible and reviewable for the team.

What should a useful task definition contain?

  • The purpose and expected output
  • Files or information sources to use
  • Party perspective and limitations
  • Points the user must check

Do not treat a prompt as a magic command

The same prompt can produce different results across documents. The content, selected sources, and required output format need to be reconsidered for each matter.

Define version and ownership

Knowing who updated a prompt, for which task, and when makes a team standard easier to maintain. Changes can be compared on small example sets.

Add evaluation criteria

Consistency is more than similar wording. Grounding, completeness, appropriate tone, and the extent of user correction can be assessed separately.

Prompt use in Harmonity

The prompt library provides a starting point for reusing supported task definitions across a team. Every output still needs to be evaluated against its sources and purpose.
