Write a brief comment block (facts with sources, slide plan, style) followed by a script using the kit helpers, then call office with action 'author' and the deck path. The runtime returns rendered pages, a composition receipt, and an audit that must pass before finalizing.

Open the deck, take a paged snapshot to see its slides, then apply batch slide and shape operations. Each batch call returns its own audit for the edited slides, so small text, shape, or data edits never require re-authoring the whole deck.

No. The office capability has a portable backend that works without PowerPoint installed, and it uses Office on Windows in the background when present. Previews are rendered through LibreOffice in the portable path.

The runtime refuses to save a deck showing any figure not covered by the brief's facts line. Add each number to the facts list with its source (page, cell, or URL), or declare the figures as illustrative samples, then re-author.

The charts reference provides native, editable helpers for column, bar, line, area, doughnut, radar, scatter, and bubble charts, plus waterfall, dumbbell, small multiples, and tables. Data remains editable in PowerPoint after generation.

The portable preview uses LibreOffice, which spaces Hangul and CJK chart category labels by character even though the stored string is correct. Verify the underlying string before treating spacing as a defect, and disclose preview limitations when fonts are substituted.
