markdown_plus

Write or revise Markdown+ documents — plain Markdown that stays valid in any markdown viewer while adding bullet-list blocks with `**#id**` headers, inline-code `key:value` metadata, and viewer-side projection cues. Use when the user asks to write or rewrite a dev note, decision record, research report, tech spec, status report, executive brief, runbook, ADR, status report, or any AI-readable structured document; or when the user asks to convert plain Markdown or existing HTML into Markdown+. Do not use for slide decks, email drafts, or one-off short replies. Successful output is a single CommonMark-valid Markdown file whose blocks can be queried by a parser and projected into human-friendly HTML, with no `:::` fences, no raw HTML wrappers, no base64, code fences and ASCII trees preserved verbatim, and a prose companion for every figure/table/chart.
