Rich Markdown Reports

_For a report, reach for Rich Markdown that embeds existing cards — not a new card definition built just to present it._

When a user asks for a report, summary, or dashboard-style document, the tempting move is to design a new card type (a CardDef) to hold it. For most reports, don't. Compose the report as a Rich Markdown `.md` file that embeds the cards it's about — custom types the user already has, or off-the-shelf catalog cards. You get a live, rich document without inventing a one-off schema, and the embeds stay current as the underlying cards change.

The rule

When a task calls for a report, summary, meeting notes, briefing, or any write-up of one or more cards:

• Default to Rich Markdown, not a new card definition. Reach for a .md file that embeds existing cards before you consider authoring a bespoke CardDef to represent the report.
• Embed the cards the report is about with BFM directives instead of describing them in prose — custom or off-the-shelf cards both work.
• Reference live data rather than copying values into the text, so the report stays current as the cards change.
• Structure it with headings so it's navigable.

Write it as a `.md` file in a realm — do not paste it into the chat. The card and file embeds only render as live cards when the markdown lives as a file in a realm; the same BFM typed into a chat reply stays raw text and the embeds don't resolve. Save it to a realm the user can write to — see Pair with below for how to create the file. A report that never becomes a realm file hasn't used this skill.

Pair with

• `boxel-flavored-markdown` — the directive grammar your embeds use (:card / ::card / ::file, embed formats, fenced renderers). Pick the format that fits the report.
• `source-code-editing` — the run-realm-code tool used to write the file to the realm. It works the same for a .md file as for code, so use it here even though a report isn't source code.

Don't use for

• A reusable, structured, or interactive artifact. If the deliverable needs a typed schema, edit forms, or its own behavior — not just a document that presents other cards — a CardDef is the right tool, not Rich Markdown.
• Content that references no Boxel cards or files — plain markdown is fine there.
• BFM grammar edge cases or a card's rendering internals — that's the boxel-flavored-markdown skill.
