Its what im doing to share notes and creds with my agent. Works great! I had my agent make a skill to use the keepassxc cli so whenever it makes a new account it’ll store the creds in there (so i can get into them if i have to) and its how i bootstrapped initial email and other creds). And then theres an obsidian skill, so we use that for pretty much all non-code data we need to share (code goes in git). So research reports, braindumps, work notes, project plans, etc. I like it way more than notion and its just software I run on my laptop.
