What it does

Gif Splitter is an agent skill from isjiamu/jiamu-skills. GIF动图切分工具，将超过指定帧数的GIF文件自动拆分成多个小文件。适用于微信公众号等平台上传GIF时遇到"帧数超限"的问题。

Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/split_gif.py`).

The repository describes itself as: 甲木常用的 Agent Skills 集合，包含日常工作流中积累的高效技能扩展。 / A curated collection of Agent Skills for daily productivity workflows. The licence is MIT.

Example prompts

“/gif-splitter”

Requirements

Python 3

Workflow steps

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

读取GIF：使用Pillow库读取GIF的所有帧和每帧的持续时间
计算分片：根据总帧数和最大帧数限制，计算需要切分的文件数量
均匀分配：将帧数均匀分配到各个输出文件，避免最后一个文件帧数过少
保存输出：保留原始帧率和循环设置，生成优化后的GIF文件

What it can do on your machine

Read from SKILL.md and the folder at commit 3c21371. 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
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- python3
- pip3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip3, which can reach the network depending on how they are called.
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

Gif Splitter loads about 610 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 100 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~19
When it runs · the whole SKILL.md, loaded when a task matches: ~610

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); the scripts in this folder are not scanned.

GIF 动图切分工具

概述

这个技能用于解决上传GIF到微信公众号等平台时遇到的"图片帧数超过300帧"限制问题。它会自动检测GIF帧数，并将超限的GIF智能切分成多个符合要求的小文件。

使用场景

当用户遇到以下情况时触发此技能：

上传GIF到微信公众号提示"帧数超过300帧"
需要将大GIF拆分成多个小GIF
需要检查GIF文件的帧数信息
需要将GIF拆分后确保每个文件不超过指定大小

快速开始

当用户需要切分GIF时，运行以下脚本：

bash

# 切分单个GIF文件（默认最大280帧）
python3 ~/.claude/skills/jiamu-skills/gif-splitter/scripts/split_gif.py "GIF文件路径"

# 切分文件夹中所有GIF
python3 ~/.claude/skills/jiamu-skills/gif-splitter/scripts/split_gif.py "文件夹路径"

输出目录：原文件所在目录下的 split_output/ 文件夹

依赖环境

安装 Pillow

bash

pip3 install Pillow

验证安装

bash

python3 -c "from PIL import Image; print('Pillow 安装成功')"

使用命令

基础用法

bash

# 切分单个文件
python3 scripts/split_gif.py "动图.gif"

# 切分整个文件夹
python3 scripts/split_gif.py ~/Desktop/gif文件夹/

自定义参数

bash

# 指定最大帧数（默认280帧，微信限制300帧）
python3 scripts/split_gif.py "动图.gif" --max-frames 200

# 指定输出目录
python3 scripts/split_gif.py "动图.gif" -o ~/Desktop/output

# 仅查看GIF信息，不切分
python3 scripts/split_gif.py "动图.gif" --info

# 组合使用
python3 scripts/split_gif.py ~/gifs/ --max-frames 250 -o ~/output --info

参数说明

参数	说明	默认值
`path`	GIF文件或文件夹路径	必填
`--max-frames`, `-m`	每个输出文件的最大帧数	280
`-o`, `--output`	输出目录	原目录下的 `split_output/`
`--info`	仅显示GIF信息，不执行切分	False

工作原理

切分算法

读取GIF：使用Pillow库读取GIF的所有帧和每帧的持续时间
计算分片：根据总帧数和最大帧数限制，计算需要切分的文件数量
均匀分配：将帧数均匀分配到各个输出文件，避免最后一个文件帧数过少
保存输出：保留原始帧率和循环设置，生成优化后的GIF文件

示例

原文件：演示动画.gif（740帧，5.7MB）

切分结果：

演示动画_第1部分.gif  (247帧, 约2MB)
演示动画_第2部分.gif  (247帧, 约2MB)
演示动画_第3部分.gif  (246帧, 约2MB)

平台限制参考

平台	帧数限制	文件大小限制	建议 `--max-frames`
微信公众号	300帧	10MB	280（默认）
微信聊天	无明确限制	25MB	根据需要
微博	无明确限制	20MB	根据需要

常见问题

切分后文件比原文件大？

这是正常现象。原因：

原GIF可能使用了全局调色板优化
切分后每个文件需要独立的调色板
帧间压缩效果降低

解决方案：适当增加 --max-frames 减少切分数量

切分后动画速度变了？

脚本会保留原始帧率。如果发现速度异常，可能是原GIF的帧时间信息不完整。

如何只查看GIF信息不切分？

bash

python3 scripts/split_gif.py "动图.gif" --info

输出示例：

文件: 演示动画.gif
帧数: 740 帧
大小: 5.70 MB
尺寸: 800x600
状态: 需要切分（超过 280 帧）

输出格式

输出文件命名规则：{原文件名}_第{序号}部分.gif

例如：

演示.gif → 演示_第1部分.gif, 演示_第2部分.gif

技术细节

库依赖：Pillow (PIL)
Python版本：3.6+
支持格式：GIF（动态/静态）
输出优化：启用GIF优化压缩

How do I install Gif Splitter in Claude Code?

Run `npx skills add isjiamu/jiamu-skills --skill gif-splitter -a claude-code`. Or copy the skill folder (gif-splitter in isjiamu/jiamu-skills) into .claude/skills/gif-splitter in your project. Claude Code loads it when a task matches its description.

How do I install Gif Splitter in Codex?

Can I use Gif Splitter 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 isjiamu/jiamu-skills --skill gif-splitter -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/gif-splitter, .gemini/skills/gif-splitter, .github/skills/gif-splitter and .opencode/skills/gif-splitter in your project.

What does Gif Splitter need to run?

Going by SKILL.md and its folder, Gif Splitter needs Python for the scripts in its folder and the command-line tools its instructions call (python3 and pip3). Our summary lists: Python 3.

Does Gif Splitter access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Gif Splitter safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Gif Splitter use?

Gif Splitter is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Gif Splitter use?

About 610 tokens (SKILL.md is roughly 2.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
