3	Generate studio-quality Nano Banana Pro prompts that turn casual product snapshots into professional e-commerce imagery.
4
5	## How It Works
6
7	This skill acts as a Creative Director: it analyzes the uploaded product image, identifies the subject, and crafts a detailed photography-grade prompt that Nano Banana Pro can execute with a reference image. The output is a ready-to-paste English text prompt — the user takes it to Gemini App, Google AI Studio, or any Nano Banana Pro endpoint.

9	## Workflow
10
11	### Step 1: Validate Input
12
13	1. Confirm the user has uploaded at least one image. If not, ask them to upload the product photo they want to transform.
14	2. Carefully examine the uploaded image(s). Pay attention to:
15	- What is the main product/subject? (e.g., a mechanical watch, a ceramic mug, a pair of sneakers)
16	- What is the product's material, color, texture, key visual features?
17	- What is the current context? (e.g., on a messy desk, held in hand, in packaging)
18	- Are there any brand markings, logos, or distinctive design details worth preserving?
19
20	### Step 2: Confirm Subject & Gather Preferences
21
22	Use `ask_user_input_v0` to collect the user's preferences in one go:
23
24	Question 1 — Subject Confirmation (single_select):
25	Present what you identified as the main subject and ask the user to confirm or correct.
26	- Options: your identified subject description, or "其他（我来描述）"
27
28	Question 2 — Scene Type (single_select):
29	- 纯白底主图（White Background Hero Shot）
30	- 生活场景图（Lifestyle Shot）
31	- 创意氛围图（Creative Atmosphere）
32	- 自定义场景（Let me describe）
33
34	Question 3 — Aspect Ratio (single_select):
35	- 1:1（默认，适合淘宝/Amazon）
36	- 4:3（横版展示）
37	- 3:4（竖版/小红书）
38	- 16:9（Banner/横幅）
39
40	### Step 3: Generate the Prompt
41
42	Read the reference file at `references/prompt-templates.md` for scene-specific templates and photography parameters, then compose the final prompt.
43
44	#### Prompt Composition Principles
45
46	Nano Banana Pro is a "Thinking" model built on Gemini 3 Pro. It understands intent, physics, and composition. The key principles:
47
48	1. Think like a Creative Director, not tag soup. Write in natural, descriptive English sentences — not comma-separated keyword lists. Nano Banana Pro's text encoder is an LLM that reasons about the prompt before generating.
49
50	2. 6-element structure — Every prompt should include:
51	- Subject: Precise description of the product with material, color, and distinguishing features
52	- Composition: Camera angle, framing, how the product fills the frame (~85-90%)
53	- Camera & Lens: Focal length (e.g., 85mm), aperture (e.g., f/8), ISO
54	- Lighting: Specific setup (softbox, key light angle, fill ratio, rim light)
55	- Style: The overall aesthetic (commercial product photography, editorial, etc.)
56	- Technical specs: Resolution and aspect ratio
57
58	3. Reference image directive — Always start with a clear instruction to use the uploaded image as reference: "Using the provided reference image as the product source, ..."
59
60	4. Negative instructions — Include what to exclude: no text, no watermarks, no hands, no distracting elements.
61
62	5. Resolution & Aspect Ratio — Specify the exact output: "Generate at 2K resolution (2048×2048 for 1:1)" or the appropriate dimensions for the chosen ratio.
63
64	#### Output Format
65
66	Present the prompt in a clean code block that the user can copy directly:
67
68	```
69	📸 Ecom Shot — {Product Name}
70	━━━━━━━━━━━━━━━━━━━━━━━━━━━━
71
72	Scene: {scene type}
73	Aspect Ratio: {ratio}
74	Resolution: 2K
75
76	--- Prompt (copy below) ---
77
78	{the generated prompt text}
79
80	--- End Prompt ---
81	```
82
83	After the prompt, add a brief "💡 Tips" section with 1-2 actionable suggestions:
84	- How to iterate if the result isn't perfect (e.g., "If the lighting feels flat, try adding: 'with dramatic side lighting creating deep shadows'")
85	- Whether multi-turn editing could help (e.g., "After generating, you can ask Gemini to 'make the background slightly warmer'")
86
87	### Step 4: Iterate if Needed
88
89	If the user wants to adjust the prompt:
