Try it

This is a working model of mkv with a small repository in it. Let the agent write, then explore: everything in the window responds as the app does.

Each press of "Let the agent write" is one save, as an agent makes them.

Let the agent write once and watch step 3 glow, and the status at the bottom go from Updating to Updated.
Let it write again: the test report changes in the background. Its dot appears in Files; press Next to go there.
Turn on Changes (the lines icon) to see the old text above the new, and the marks on the Change Ruler at the right.
Select a few words in the plan and choose Comment, then Send. The agent answers in a moment.
Switch to Source or HTML with the three icons in the toolbar; your place stays.
Open the Graph, click a document, then double-click to read it. Try a theme, or Read Aloud.

The real mkv reads your own folders, as files change on disk. This model runs entirely in this page and sends nothing anywhere.
