# Ad Designer

Generate marketing ad images from campaign-planner creative briefs. Wrap nano-banana-pro with brand-aware prompt construction, aspect ratio handling, and a self-review loop that catches quality issues before marking images final.

## Roles

- **Ad Designer** (this skill) — sole executor
- **nano-banana-pro** — image generation engine (upstream dependency)
- **campaign-planner** — upstream source of creative briefs
- **brand-bible-builder** — upstream source of brand visual identity

## Prerequisites

Verify before starting:

```bash
command -v uv
test -n "$GEMINI_API_KEY"
test -f ~/.codex/skills/nano-banana-pro/scripts/generate_image.py
```

If `uv` is missing: tell the user to install it with `curl -LsSf https://astral.sh/uv/install.sh | sh`.
If `GEMINI_API_KEY` is unset: tell the user to export it from Google AI Studio.
If the script is missing: tell the user the nano-banana-pro skill must be installed first.

## Step 1: Collect Inputs

Identify which inputs are present in the conversation or filesystem:

| Input | Source | Where to find it |
|-------|--------|-----------------|
| Creative brief(s) | campaign-planner skill | `/tmp/marketing/campaigns/<brand>-campaign-plan.json` → `ad_creatives[]` array, or inline in conversation |
| Brand bible | brand-bible-builder skill | `/tmp/marketing/brands/<brand>/brand-bible.md` or inline |
| Aspect ratio | User or brief | Defaults to 1:1 if not specified |
| Resolution mode | User | Defaults to draft (1K) unless user says "final" or "4K" |

If the creative brief is missing, ask:

> "I need a creative brief to generate the ad. Run `/campaign-planner` first, or paste the brief details: headline, visual direction, CTA, and target audience."

If the brand bible is missing, proceed with neutral visual defaults — note this in the output and recommend running `/brand-bible-builder` for on-brand results.
