# amazon-white-background Turns a product photo into an Amazon main image with a pure white background and the product filling at least 85% of the frame, then checks the file with a script. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · ★ 120 - Author: xianyu110 - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/xianyu110/ecommerce-image-skills/tree/HEAD/skills/amazon-white-background/SKILL.md - Updated: 2026-10-08 - HTML: https://affpapa.org/en/nevibecode/skills/amazon-white-background ## What it does The skill starts by writing an identity lock for the product: shape, colour, logo spelling, included parts. That block goes into every prompt unchanged, so a creative instruction cannot quietly redraw the item. Generation runs through GPT Image 2.5, either with the agent's own image tool or with `scripts/generate.py` and a `GPTIMAGE_API_KEY`. A check comes before delivery. `scripts/check_main_image.py` measures how much of the border band is pure white, how much of the background is exactly #FFFFFF, the product's share of the frame and the longest side in pixels. Grey or off-white background? Run the same script with `--fix` to snap near-white pixels to #FFFFFF and re-crop to 87%. The check needs `pillow` and `numpy` installed. Generation depends on an outside image API. Without a key or a built-in image tool you are left with the prompt text and a browser link. Amazon wants the longest side at 1000 px or more, 1600–2000 px recommended, and nothing printed over the product: no badges, borders or watermarks. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add xianyu110/ecommerce-image-skills --skill amazon-white-background -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/amazon-white-background/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/amazon-white-background/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add xianyu110/ecommerce-image-skills --skill amazon-white-background -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/amazon-white-background/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add xianyu110/ecommerce-image-skills --skill amazon-white-background -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/amazon-white-background/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install xianyu110/ecommerce-image-skills amazon-white-background ``` 2. **Manually: put the files in place** - File: `.github/skills/amazon-white-background/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add xianyu110/ecommerce-image-skills --skill amazon-white-background -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/xianyu110/ecommerce-image-skills --path skills/amazon-white-background ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/amazon-white-background/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add xianyu110/ecommerce-image-skills --skill amazon-white-background -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/xianyu110/ecommerce-image-skills/tree/HEAD/skills/amazon-white-background/SKILL.md ## When to use it - strip the background from a supplier photo down to #FFFFFF - fit the product into 85% of the frame without clipping - keep the logo and label text intact through generation - verify a finished image against Amazon main-image rules - produce a hero image for a Walmart or eBay listing ## Example prompts - Make an Amazon white-background main image from `product.jpg`, the item is a mug with a logo - Run the check script on `out/amazon-white-background.png` and fix the background if it is not pure white - Generate a version with packaging: box behind and to the right, both fully visible ## Source text · SKILL.md · MIT Below is the content of a third-party file.

Works with Claude Code, Codex, Cursor and any agent that loads `SKILL.md`. Default model: GPT Image 2.5 **Sunburst**. ## Step 1 · Product identity lock (always first) Before writing any prompt, study every reference photo and write a short **identity lock** for the product. Paste it verbatim into **every** prompt this skill produces, and never let a creative instruction override it. ```text PRODUCT IDENTITY LOCK (do not change): - Shape & proportions: - Colour & finish: - Logo & printed text: - Parts & details: - Must NOT appear: ``` Rules: - Only use facts visible in the photos or confirmed by the user. If something is unknown (size, capacity, material), ask or leave it out — never invent specs or certifications. - If the user gave no photo, ask for one (front view at minimum). Text-only generation is allowed but say the result is a concept, not the real product. ## Step 2 · Pick the model | Use **Flare** (`gpt-image-2.5-flare`, default) | Switch to **Sunburst** (`gpt-image-2.5-sunburst`) | |---|---| | New scenes, backgrounds, layouts, many quick variations | The product's logo / label / small text must survive exactly | | Text-to-image concepts | Local edits: swap background, recolour, remove objects, keep everything else | ```` END THIRD-PARTY FILE cc36eb41ca6b1d2b The third-party file has ended.
