Writer

The Writer is a markdown document surface — a place to draft articles, posts, briefs, and notes with a live preview, an outline, and writing stats. Open it from the toolbar Tools (wrench) → Writer, or say “new document” / “draft an article about …”.

Write and preview

The left side is a markdown editor (the same CodeMirror engine as the Code pane); the right side renders it live. Switch between Edit, Split, and Preview with the toolbar buttons. The outline lists your headings — click one to jump the editor to it. The status line shows word count, estimated read time, and average sentence length as a quick readability cue.

Draft with an agent

Ask an agent to write into the document: use “draft an article about X” from the command bar (it opens a Writer and fills it), or the Draft action in the pane to generate or continue from a prompt. Mastery HQ runs a one-shot with a detected coding CLI and inserts the markdown — you then edit, restructure, and polish it yourself.

Export and open

• Export writes the document to a .md file via the save dialog.
• Open loads a .md (or any text) file from disk into the Writer.
• Copy puts the markdown on your clipboard.

Files are read and written with Mastery HQ’s granted-path rules — the app only touches files you pick.

Tips

• The Writer pairs with the Blog Studio and Research Desk starter recipes, which open it alongside an agent, the browser, and a board.
• Keep drafts small-to-medium here; for large manuscripts, export to a file and open it in the Code pane or your editor of choice.
