OpenAI “Prompt Optimizer” Tool | Write Better Prompts Faster – Rajeev Pentyala – Technical Blog on Power Platform, Azure and AI

Writing good prompts can be tricky, but OpenAI just made it easier with their Prompt Optimizer tool.

This tool takes your draft prompts and suggests improvements to make them clearer, more effective, and tailored for better AI responses.

It’s a great way to save time and get more out of every interaction with GPT-5.

Prerequisites

You just need a free OpenAI account to access the Prompt Optimizer tool . No premium plan is required.

Trying Out the Prompt Optimizer with a Dynamics Plugin Example:

Let’s say you want code for a C# plugin on the Account table. You might start with a simple prompt like:

Write a plugin for Dynamics CRM to update account data.

This works, but it’s too vague—no mention of the pipeline stage, error handling, or coding best practices.

Now, let’s use the Prompt Optimizer to improve it:

Open the Prompt Optimizer tool
Provide your draft prompt

Click on Optimize
Prompt Optimizer generates a refined version, which might look like this:

Click on Copy to copy the generated prompt.

Developer: # Role and Objective
- Develop a Dynamics CRM plugin that updates account data based on specified triggers or conditions.

# Checklist
- Begin with a concise checklist (3-7 bullets) outlining: (1) plugin registration, (2) event handling logic, (3) account data retrieval, (4) business rule implementation, (5) error handling and logging, (6) validation via test data, (7) documentation within the C# code.

# Instructions
- The plugin must listen for particular events (such as create or update) on the Account entity.
- Upon trigger, retrieve relevant account information, apply necessary updates, and commit the changes back to Dynamics CRM.
- Ensure error handling and logging for maintainability.
- Follow Dynamics CRM plugin development best practices.

# Context
- Target system: Microsoft Dynamics CRM.
- Scope: Only the Account entity (other entities are out of scope).
- No UI changes are required; this is a back-end plugin.

# Planning and Verification
- For each substantive step (such as plugin registration, event handling, or business logic), after code changes or tool usage, validate in 1-2 lines that the step achieved the intended result. If validation fails, self-correct and retest before proceeding.
- Plan: Register the plugin, implement business logic, test with sample data, and validate correct updates to Account records.
- Verification: Updates should reflect accurately in Dynamics CRM and appear in the audit history of the account.

# Output Format
- Deliver as a C# class suitable for plugin registration in Dynamics CRM, with all required comments and regions.

# Verbosity
- Use clear, descriptive variable and method names; provide inline comments for clarity.

Notice how the optimizer enhances the prompt with all the right details. You can further tweak it—remove lines you don’t need or adjust for your specific scenario—before using it.

Try it yourself: Head over to the OpenAI Prompt Optimizer, paste one of your own prompts, and see how much better the results get. Don’t forget to tweak the refined prompt to match your exact scenario!
