What it does

Image Editing is an agent skill from ZJU-REAL/Easel. 通用图像处理加工：改尺寸/缩放、裁剪、补边适配平台尺寸、格式转换（png/jpg/webp）、压缩到目标大小、加文字或图片水印、圆角、多图拼接、生成缩略图、读图片信息。基于 imageops.py 确定性处理。使用时机：用户说"改尺寸"、"缩放图片"、"裁剪"、"压缩图片"、"加水印"、"转格式"、 "圆角"、"拼图/多图联排"、"缩略图"、"适配小红书/朋友圈尺寸"、"把图 pad 成 1:1"。和 card-（卡片类）的区别：card- 是"HTML 设计→渲染出图"， image-editing 只加工已有图片，不负责视觉设计。

Its SKILL.md is about 980 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `EASEL-META.md` and `references/platform-sizes.md`).

It sits in Media & Creative, covering Image editing. The repository describes itself as: An open-source AI agent for social media — discover trends, create content, publish everywhere, and learn what works across Xiaohongshu, Douyin, Zhihu, Bilibili, and more.🎨一个开源的… The licence is Apache-2.0.

When your agent uses it

Tasks that involve Image editing

Example prompts

“拼图/多图联排”
“适配小红书/朋友圈尺寸”
“把图 pad 成 1:1”
“/image-editing”

Requirements

Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

确认输入图片存在、明确目标操作与参数
从项目根目录运行 image_ops.py 对应子命令（见下）
需要平台尺寸时，查 references/platform-sizes.md 取推荐比例/像素
回报输出路径与尺寸；多步操作可串联（如先 resize 再 compress）

What it can do on your machine

Read from SKILL.md and the folder at commit 278f420. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Image Editing loads about 983 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 73 tokens; SKILL.md has 104 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~73
When it runs · the whole SKILL.md, loaded when a task matches: ~983
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: image-editing
description: 通用图像处理加工：改尺寸/缩放、裁剪、补边适配平台尺寸、格式转换（png/jpg/webp）、压缩到目标大小、加文字或图片水印、圆角、多图拼接、生成缩略图、读图片信息。基于 image_ops.py 确定性处理。使用时机：用户说"改尺寸"、"缩放图片"、"裁剪"、"压缩图片"、"加水印"、"转格式"、 "圆角"、"拼图/多图联排"、"缩略图"、"适配小红书/朋友圈尺寸"、"把图 pad 成 1:1"。和 card-*（卡片类）的区别：card-* 是"HTML 设计→渲染出图"， image-editing 只加工已有图片，不负责视觉设计。
layer: produce

图像处理加工

对已有图片做确定性处理：缩放/裁剪/补边/转格式/压缩/水印/圆角/拼接/缩略图。所有操作走 skills/shared/scripts/image_ops.py（纯 Pillow），不即兴写脚本。

输入

一张或多张已存在的图片文件路径（png/jpg/webp 等 Pillow 支持格式）
目标操作与参数（尺寸、比例、质量、水印文字、拼接方式等）

输出

处理后的图片文件（路径由用户指定或默认写入 outputs/主题名/）
每条命令回显 ✅ 路径 (宽x高, 大小KB)；info 输出 json

边界（与 card-* 划清）

card-quote / card-xiaohongshu / poster-hero / comparison-card = 设计并渲染新图（HTML→截图）
image-editing = 加工已有图片，不做视觉设计，不生成内容，只做像素级处理
需要"从数据/文字生成图" → 用 chart/infographic/card-*；本 SKILL 只处理现成图片文件

执行步骤

确认输入图片存在、明确目标操作与参数
从项目根目录运行 image_ops.py 对应子命令（见下）
需要平台尺寸时，查 references/platform-sizes.md 取推荐比例/像素
回报输出路径与尺寸；多步操作可串联（如先 resize 再 compress）

python skills/shared/scripts/image_ops.py crop -i in.jpg -o out.jpg --width 1080 --height 1080

# 补边到目标比例（社媒适配核心）：把任意图 pad 成 1:1 / 9:16 / 16:9

领域知识：平台推荐尺寸

常用平台推荐见 references/platform-sizes.md。高频速记：

小红书竖版图文：1080×1440（3:4）；小红书视频/竖版海报：1080×1920（9:16）
朋友圈单图 / 通用方图：1:1（如 1080×1080）
横版金句/封面：16:9（如 1920×1080）；微信公众号头图 900×383
微博配图：1:1 或 4:3；抖音/视频号封面：9:16（1080×1920）

适配思路：优先 pad（补边不裁内容、不变形）保全画面；追求满版无边则 crop 居中裁到目标比例；仅需缩小体积用 resize/compress。

Profile 感知

有 Profile：水印文字默认用账号名/handle；输出比例默认贴合账号主平台（如小红书号默认 1080×1440）
无 Profile：按用户显式参数执行，比例默认保持原图，水印需用户给文字

依赖与错误处理

依赖：Pillow（已装，python -c "import PIL" 可用），纯标准库无其他第三方
脚本内建边界检查：文件不存在 / 裁剪框越界 / 非法比例或颜色 → 退出码 2 并打印 ERROR:
找不到系统中文字体时降级 PIL 默认字体并 WARN，可用 --font 指定
自检：python skills/shared/scripts/image_ops.py --selftest

Can I use Image Editing in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ZJU-REAL/Easel --skill image-editing -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/image-editing, .gemini/skills/image-editing, .github/skills/image-editing and .opencode/skills/image-editing in your project.

What does Image Editing need to run?

Going by SKILL.md and its folder, Image Editing needs the command-line tools its instructions call (python). Our summary lists: Python 3.
