@mrhandsome39.bsky.social/share-preview-builderOr open Registry in your EmDash admin and search for this name.
Permissions
Plugins get only the capabilities they declare and you approve. Your EmDash admin lists these again before anything installs.
FAQ
Does it fetch my page or check how a platform renders the card? No. It only checks the text you paste and sends nothing. Open Graph and card tags are not read.
What are the limits? You set them in display-width units, where CJK and fullwidth characters count as 2. The defaults (70 and 160) are neutral starting points, not any platform rule.
Is my text rewritten? Never. Line breaks, tabs and broken characters block the TSV so you fix the source. Spaces and invisible characters are reported, not removed.
What is in the TSV? URL, title, summary, widths, character counts and warning codes. Cells starting with = + - @ get a leading apostrophe so a spreadsheet does not run them.
Security
Requests no EmDash capabilities and no outbound hosts. It reads no content, users or settings, stores nothing and changes nothing. The pasted text is processed in the request and returned to the same editor. Access requires an editor who can edit drafts.
