Know when your architecture diagram no longer matches the code
Link a shape on your canvas to the files or folders it describes. When a pull request that touches those files merges, the shape gets a badge, shapes downstream by arrow are outlined, and one click files a review note. Open pull requests that will touch the files show a heads-up before they merge.
What you get
Per-file, not per-repo
A shape is flagged only when a merged pull request touched the files it is linked to, so alerts stay rare and believable.
Heads-up before the merge
Open pull requests that will change a linked shape show a separate badge, so reviewers see the diagram impact first.
Blast radius
Shapes downstream by arrow get a dashed outline, so you can see what else the change may affect.
Fix it in one review
Suggest update adds a review note listing the pull requests and files, in the same tray as other suggestions.
How it works
- 1Connect GitHub to your Co-Space and add the repository card.
- 2Link a shape to the files or folders it describes.
- 3Watch for the badge, review the note, then mark the shape up to date.
Questions
Does it rewrite my diagram automatically?
No. It points to what changed and lets you decide. A wrong automatic edit is worse than a pointer.
What does it need from GitHub?
Pull request metadata and the list of changed file names. It does not keep file contents or diffs.
Which diagrams does it cover?
Any shape on the canvas can be linked to repository paths.

Use case
Living architecture documentation
Keep architecture on an editable canvas wired to GitHub, tasks and decisions, so the diagram is flagged when the code moves instead of silently going stale.
