| OP didn't think to include this very important fine print. Thanks
| OP!

| Based on the number of emojis, I doubt the author even knows.

| The design of this is pretty nice, it's based on a very simple
| to add instrumentation to your agent and the rest happens in
| parallel while your workload runs which is awesome.
|
| You can probably do also what DSPy does for optimizing prompts
| but without having to rewrite using the DSPy API which can be a
| big win.

| I'm not expected to write docs the way my father's generation
| did (thank god), so I don't expect them to write the docs the
| way I would. If this gets people engaged and excited, I lose
| nothing, they get something, we're fine.
|
| As to the LLM generation claim, I don't care if it is or it
| isn't. The project seems legit, they're making claims that 3rd
| parties have verified ("Community Projects"), it looks useful
| and interesting, so I might spend more time with it soon.

| purpose? Heck yeah Microsoft
