Microsoft just dropped a gem for anyone building multi-agent LLM systems.

Introducing POML: a lightweight library that lets you structure prompts as .poml files.
https://microsoft.github.io/poml/latest/

You can pass these directly into your LLM code, keeping instructions clean, modular, and separate from logic. It even supports images and file attachments. If you're juggling 10+ agents and want cleaner, more maintainable code.

Prefer working Visually?
Check out Structured Prompt Builder—a slick React SPA that lets you design prompts with full control:

Format
‍ Role
Task
Style
️ Tone
Inputs
Steps

Repo: https://github.com/Siddhesh2377/structured-prompt-builder

At the end, you get a fully structured prompt ready to deploy.
Whether you're coding or designing, prompt clarity = agent sanity.

Sound interesting, I will try it
