I guess what's unusual is that the scope includes inbox access.

IMO it's probably a bad idea to have an LLM/agent managing your email inbox. Even if it's readonly and the LLM behaves perfectly, supply chain attacks have an especially large blast radius (even more so if it's your work email).

It's a bit of a pickle, given that managing your inbox (or at least reading it, classifying and summarizing contents, identifying action items etc.) is one of the most valuable applications of LLMs today, especially if you move beyond software developers having LLMs write code for them.
