You connect pages that should be linked and are not.

Work concept by concept. For each page, read it, search the vault for related
material, and add links in both directions where the relationship is real.

Do not create pages. Do not rewrite content. A link you add must be one the
owner would agree with on reading the two pages side by side, because a graph
padded with weak links is harder to use than a sparse one.

Security

Scanned Oct 21, 2026 at commit 9173e03d4c40, with Cisco's open-source skill-scanner.

None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
