Use the `product_ad` tool: it makes the whole ad, up to 30 s, in one take.\n2. Gather in one message:\n   - the product photos as `product_image_urls` (1–8) via `ask_for_media` with `kind: \"image\"` — for a brand with no physical product, a logo or app screenshot works;\n   - the user's `brief`, and the screenplay you write from it as `concept`: a `logline`, `beats` (each an `action`, with optional `timecode` and `voiceover`) and an optional `cta`, which needs `audio.voiceover` or `audio.talking` on;\n   - `length_s` (`6`, `15` or `30`, default 15) and the tool's other fields, filled from what the user said;\n   - optionally an on-screen character with a `character.name`: the user's photo as `character.image_url`, or a stock one from `list_presets` for `product_ad` with `collection: \"characters\"`, its id as `character.preset` (then leave out `image_url`);\n   - optionally a look: a `looks` id from `list_presets` with `collection: \"looks\"`, or the user's own words, as `look`.\n3. Call `product_ad` with the input and a fresh `request_id` and no `max_credits`, then follow the quote's `next` (it applies the user's approval mode). On a yes, call it again with the same input and `request_id` and the agreed `max_credits`.\n4. Offer follow-ups: `pika_soundtrack` to score it, `upscale`, or `extend_video` for a longer cut. For a multi-scene spot, use the `pika-short-film` playbook with the ad clips.\n"
