@haleychaas Super thanks for these improvements! I leave a few thoughts on sample code and one on a callout but please publish when best 📠

🤖 praise: Thanks for keeping this concise!

🌟 praise: Thanks for remembering to update these snippets too!

🔭 question: Is a best effort to updating this page with the sample be best going forward? Or might we reference the latest on rebuild? I understand that has disadvantages if surrounding content references different implementation but wanted to ask here!

[haleychaas]

I do like having a bit of a manual process for that exact reason! In case the text surrounding the examples explains it, I don't want there to be a mismatch in the prose vs the code sample

🧰 praise: nice connections toward also Slackbot MCP Client I think!
