ABOUT THIS TOOL:

• This tool is part of a toolchain that generates and provides test cases for a prompt template.
• This tool helps an AI assistant to generate a prompt template based on one of the following:
  1. feature requirements defined by a user - in which case the tool will generate a new prompt template based on the feature requirements.
  2. a pre-existing prompt or prompt template that a user wants to test, evaluate, or modify - in which case the tool will convert it into a more structured and testable prompt template while leaving the original prompt language relatively unchanged.
• This tool will return a structured prompt template (e.g. template) along with a context schema (e.g. contextSchema) that defines the expected input parameters for the prompt template.
• In some cases, a user will want to add test coverage for ALL of the prompts in a given application. In these cases, the AI agent should use this tool to generate a prompt template for each prompt in the application, and should check the entire application for AI prompts that are not already covered by a prompt template in the ./prompts directory.

WHEN SHOULD THIS TOOL BE TRIGGERED?

• This tool should be triggered whenever the user provides requirements for a new AI-enabled application or a new AI-enabled feature of an existing application (i.e. one that requires a prompt request to an LLM or any AI model).
• This tool should also be triggered if the user provides a pre-existing prompt or prompt template from their codebase that they want to test, evaluate, or modify.
• This tool should be triggered even if there are pre-existing files in the ./prompts directory with the <relevant-name>.prompt.yml convention (e.g. bedtime-story-generator.prompt.yml, plant-care-assistant.prompt.yml, customer-support-chatbot.prompt.yml, etc.). Similar files should NEVER be generated directly by the AI agent. Instead, the AI agent should use this tool to first generate a new prompt template.

PARAMETERS:

• params: object
  • prompt: string (the feature requirements or pre-existing prompt/prompt template that will be used to generate a prompt template. Can be a multi-line string.)
  • promptOrigin: "codebase" | "requirements" (indicates whether the prompt comes from an existing codebase or from new requirements)
  • model: string (the model that the prompt template will be tested against. Explicitly specify the model if it can be inferred from the codebase. Otherwise, defaults to gpt-4.1-mini.)
  • temperature: number (the temperature of the prompt template. Explicitly specify the temperature if it can be inferred from the codebase. Otherwise, defaults to 1.)

EXAMPLE USAGE (from new requirements): { "params": { "prompt": "Create an app that takes any topic and an age (in years), then renders a 1-minute bedtime story for a person of that age.", "promptOrigin": "requirements" "model": "gpt-4.1-mini" "temperature": 1.0 } }

EXAMPLE USAGE (from pre-existing prompt/prompt template in codebase): { "params": { "prompt": "The user wants a bedtime story about {{topic}} for a person of age {{age}} years old. Please craft a captivating tale that captivates their imagination and provides a delightful bedtime experience.", "promptOrigin": "codebase" "model": "claude-3-5-sonnet-latest" "temperature": 0.7 } }

TOOL OUTPUT INSTRUCTIONS:

• The tool will return...
  • a template that reformulates the user's prompt into a more structured format.
  • a contextSchema that defines the expected input parameters for the template.
  • a promptOrigin that indicates whether the prompt comes from an existing prompt or prompt template in the user's codebase or from new requirements.
• The tool output -- the template, contextSchema, and promptOrigin -- will also be used as input to the recommend_prompt_template_tests tool to generate a list of recommended tests that can be used to test the prompt template.
