105The slides skill is opinionated here: match the source aspect ratio before you rebuild layout, and default to 16:9 only when the source material does not already define the deck size. If the references are screenshots or a PDF, ask Codex to render or inspect them first so it can compare slide geometry visually instead of guessing.71The slides system skill is opinionated here: match the source aspect ratio before you rebuild layout, and default to 16:9 only when the source material does not already define the deck size.

115Image generation is most useful when the slides need a cover image, a concept illustration, or a lightweight diagram that would otherwise take manual design work.

117When several slides need related visuals, have Codex save the prompts or generation notes it used. That makes the deck easier to extend later without starting over stylistically.83When several slides need related visuals, have Codex save the prompts or generation notes it used.

121Deck automation works better when Codex treats each slide as its own decision. Some slides should preserve exact copy, some need a stronger headline and cleaner structure, and some should stay mostly untouched apart from asset cleanup or formatting fixes.87Deck automation works better when Codex treats each slide as its own decision.

123The slides skill also ships with bundled layout helpers. Ask Codex to copy those helpers into the working directory and reuse them instead of reimplementing spacing, text-sizing, and image-placement logic on every deck.89The slides system skill also ships with bundled layout helpers.

127Decks are easy to get almost right and still ship with clipped text, substituted fonts, or layout drift that only shows up after export. The slides skill includes scripts to render decks to per-slide PNGs, build a quick montage for review, detect overflow beyond the slide canvas, and report missing or substituted fonts.93Decks are easy to get almost right and still ship with clipped text, substituted fonts, or layout drift that only shows up after export.
