Each of these started as something that broke, surprised me, or contradicted the documentation. The numbers are mine and can be reproduced.

I put behaviour rules in the text my tools returned, because the proper channel never reached the model. Then a user watched the host warn them that this connector had tried to inject malicious instructions. About the shape of it, the detector was right.
A field guide to the channels between your server and the model: which ones arrive, which quietly do not, and what each one costs. Four findings, none of them from reading the specification.
