Working with a client
Share the deliverable, not everything else.
You need to get specific outputs in front of an outside party - a client, a contractor - and get their sign-off. Without handing them an account or a view of everything else you're working on.
The situation
Sharing work with someone outside the team is usually all-or-nothing. Either you email files around and lose the trail of what was approved, or you set them up with an account and now they can see far more than the one thing you meant to show them. Neither is comfortable when the other side is a client paying for a deliverable.
What Kythene does
You share a single tag by code. The other side opens it, views the outputs under that tag, comments on the specific block that needs changing and approves as a guest - no sign-up, and no access to the rest of your team's work. They see exactly what you shared and nothing more.
Their block-level comments and approvals land against the specific revision they were looking at - and come back to you and your AI over MCP - so you get a clean record of what the client actually signed off, down to the paragraph, not a "yes, looks good" buried in an email.
The win: outside collaboration with block-level review and a sign-off trail, and nothing over-shared.
Share the work, and only the work.
