What you supply

{prompt}optional

Text to place in the composer.

{folder}optional

Absolute path to a folder to attach.

Repeatable — pass folder more than once to attach several.

{file}optional

Absolute path to a file to attach.

Repeatable, like folder. Unlike the Claude Code link, file actually works here.

The only link in this registry that attaches more than one thing: both folder and file repeat, so a single URL can hand a session a whole working set.

Every attached folder raises its own confirmation dialog, every time. Attach four folders and you will be asked four times — which is tedious by design.
