In short:
ak-creativitysearches a library of 55 styles, 18 platforms, 12 voiceover types, 17 music genres and 30 campaign types, then returns a brief: visual style, platform specs, voiceover, music and things to avoid. If you only need one pick, it searches that area directly. It does not make images or videos, and it gives no performance numbers without a source.

Summary
Use it when you need a creative direction for an ad, a video or a social content series, or when you only need to settle the voiceover, music or style. You do not need it when the direction is already clear and only production is left: that happens in other tools. If you already have an approved brief, paste it in and it reuses it instead of writing a new one.

D --> EFour things to know:
| Point | Question | Example |
|---|---|---|
| Four inputs | What kind of campaign, for whom, which industry, posted where? | Product launch, Gen Z audience, wellness app, short vertical video |
| Full brief or one area | Do you need a whole creative direction, or just one decision? | A new campaign with no direction gets a brief. If you only need a voiceover, it searches the voiceover area directly. |
| Suggestions, not rules | Do you have to follow the style the library suggests? | The library suggests a neon style for a young audience, but your brand is calm and upscale, so it drops it, with a reason taken from the brief. |
| Numbers need a source | When can it say "this style lifts engagement by X%"? | Only with original research that states its date and scope. Without that, the number goes, and it only says why the style fits plus a hypothesis to test. |
Sample prompt for a new campaign:
/ak-creativity Build a creative brief for the launch campaign of the meditation app <app name>.
Audience: Gen Z. Industry: wellness app. Channel: short vertical video 9:16.
Constraints: keep the current brand colors, no music that needs a separate paid license.
Done when: there is a style, voiceover, music, video specs and a list of things to avoid.This skill has no flags.
