Build a styled PDF from scratch using reportlab Platypus. Use when the user wants a PDF — brief, report, resume, writeup, doc, recipe, anything. You write the build script fresh every time so the design fits the request. NOT for reading existing PDFs (that's read_file).

Build a diagram — flowchart, architecture/system diagram, sequence, mind map, org chart, decision tree — as a self-contained HTML/SVG that opens in any browser, OR as an editable Excalidraw file. Use when the user wants a diagram, chart of boxes-and-arrows, system design picture, or flow. NOT for data charts (that's a chart inside make-pdf) or for reading an existing diagram.

Build a styled PowerPoint deck. Prefer the bundled pptxgenjs renderer (designed cards, real timelines, stat callouts, auto-opens); fall back to python-pptx only when Node is missing. Use when the user wants slides / a deck / a pitch / a presentation. NOT for reading existing decks.

Operate on an EXISTING PDF — split, merge, extract/delete pages, rotate, search for text across pages, or pull images. Use when the user wants to "split this PDF", "merge these PDFs", "grab pages 3-7", "find where it mentions X", "rotate", or OCR a scanned PDF. NOT for creating a styled PDF (that's make-pdf) or just reading one (that's read_file/summarize_file).

Make ASCII art — a big text banner/figlet, an image converted to ASCII, or a boxed/framed message. Use when the user wants a banner, ASCII logo, text-as-art, "turn this image into ASCII", or terminal eye-candy. Output prints in the terminal or saves to a .txt.

Build an Excel (.xlsx) spreadsheet from rows of data or a TSV/CSV outline. Use when the user asks for a "spreadsheet", "Excel", "xlsx", or to "organize this as a table I can sort in Excel".
